1. Introduction

1.2 Turning Module Overview The SolidCAM Turning module enables you to prepare the tool path for the following operations: Face Turning SolidCAM enables you to perform turning of facial profiles. The principal working direction is the X-axis direction.

Turning SolidCAM enables you to prepare the tool path for all types of external and internal turning operations: long external, long internal, face front, and face back.

Drilling SolidCAM enables you to perform all drilling cycles to machine the holes coincident with the revolution axis of the part.

5

Threading SolidCAM enables you to prepare the tool path for all types of external and internal threading.

Grooving SolidCAM enables you to prepare the tool path for all types of external and internal grooving and parting.

Angled Grooving SolidCAM enables you to perform inclined grooves. The geometry defined for this operation must be inclined relative to the Z-axis of the CAM-Part Coordinate System..

Cutoff SolidCAM enables you to perform cutoff machining. This operation is used to cut the part or to perform a groove whose width is exactly the same as the tool width. The cutting can be performed using CNC-machine cycles; chamfers and fillets can also be generated.

1. Introduction

Trochoidal Turning SolidCAM enables you to turn complex profiles using the Trochoidal cutting strategy. The cutting es are rounded in the beginning and in the end to result in smooth optimized tool path that enables you to use high cutting speed and reduce tool wear. Balanced Rough SolidCAM enables you to work with two tools performing roughing cuts at the same time. The Master submachine and Slave submachine should have the same Table. Manual Turning SolidCAM enables you to perform turning according to your own geometry regardless of a stock model, target model, or envelope.

Sim. tilted turning SolidCAM enables you to perform machining of curveshaped tool paths using tilting capabilities of tools with round insert. The tool tilting is defined by specifying lines that indicate the tool vector change.

7

1.3 Mill-Turn Module Overview The Mill-Turn module is intended for programming of 3-, 4- and 5-axis multi-task machines that combine several capabilities into one machine and especially for programming of 5-axis milling CNC-machines with turning capabilities (e.g. DMU FD-series of DMG, Okuma, Mazak, Nakamura, Index, Chiron). This functionality provides you with a number of significant advantages: • The Mill-Turn module provides you with full functionality of the Coordinate System definition, identical to that of SolidCAM Milling. • You can use the same coordinate system for milling as well as for turning without additional definition. • You can define a Stock model to be used in SolidCAM Milling as well as in SolidCAM Turning operations. • The Mill-Turn module enables you to perform all types of Milling and Turning operations using the same post-processor. • The Mill-Turn module enables multi-turret and multispindle programming, with turret synchronization and full machine simulation. • Using the Mill-Turn module, you do not need to learn new rules; you just work in regular milling environment and can add turning operations as needed.

1. Introduction

1.4 Basic Concepts Every manufacturing project in SolidCAM contains the following data: CAM-Part

The CAM-Part defines the general data of the workpiece. This includes the model name, the coordinate system position, tool options, CNC-controller, etc. Geometry

By selecting Edges, Curves, Surfaces or Solids, define what and where you are going to machine. This geometry is associated with the native SolidWorks model. Operation

An Operation is a single machining step in SolidCAM. Technology, Tool parameters and Strategies are defined in the operation. In short, operation means how you want to machine.

1.5 Process Overview Three major stages of the SolidCAM Manufacturing Project creation process are: CAM-Part definition

This stage includes the definition of the global parameters of the Manufacturing Project (CAM-Part). You have to define Coordinate Systems that describe the positioning of the part on the CNC-machine. Optionally, you can define the Stock model that will be used for milling operations and the Target model that has to be obtained after the machining. Machine Setup definition

When the part is to contain Turning operations, the clamping fixture has to be defined in order to supply SolidCAM with the information about fixing the part on the CNC-machine and the part position relative to the machine. Operations definition

SolidCAM enables you to define turning and milling operations. During the operation definition, you have to select the Geometry, choose the tool from the Part Tool Table (or define a new one), define a machining strategy and a number of technological parameters.

The CAM-Part definition process consists of the following stages: CAM-Part creation

CNC-Machine definition

Coordinate System definition

Setup

Stock model definition

Target model definition

• CAM-Part creation. According to default settings, the CAM-Part name and location are defined automatically. However, you can define them manually, if you choose the manual option. At this stage, SolidCAM defines the necessary system files and a folder to allocate the place to store SolidCAM data. • CNC-Machine definition. It is necessary to choose the CNC-controller. The controller type influences the Coordinate System definition and the Geometry definition. • Coordinate System definition. You have to define the Coordinate System, which is the origin for all machining operations of the CAM-Part. You can create multiple CoordSys positions and in each machining step select which CoordSys you want to use for the operation. • Setup. You have to define the clamping fixture, the initial stock position on main or back spindle and the position of the part zero with reference to the main or back spindle. • Stock model definition. It is necessary to define a boundary of the stock that is used for the CAM-Part machining. • Target model definition. SolidCAM enables you to define the model of the part in its final stage after the machining. The following exercises describe the full process of the CAM-Part definition. It is recommended to complete the stages in order to understand how the CAM-Part features are built. For this purpose, you have to turn off the automatic CAM-Part definition.

Exercise #1: CAM-Part Definition in Turning This exercise illustrates the process of the CAM-Part definition in SolidCAM. In this exercise, you have to create the CAM-Part for the model displayed on the illustration and define the Coordinate System, the Machine Setup, the Stock and Target model, which are necessary for the part machining. The CAM-Part will be used in the exercises further on.

1.

Load the SolidWorks model

Load the Exercise1.sldprt model located in the Exercises folder. This model contains a number of features forming the solid body and several sketches used for the CAM-Part definition. 2.

Start SolidCAM

To activate SolidCAM, select SolidCAM in the Tools menu of SolidWorks and choose Turning from the New submenu or click the Turning button on the SolidCAM New toolbar.

The CAM-Part is saved in the default location defined in the CAM Settings. To learn more about saving projects, refer to the SolidCAM Turning Online Help. During this process, the structure of the CAM-Part is created.

14

2. CAM-Part Definition The structure of the CAM-Part

The CAM-Part includes Turning.prt a number of data files represented on the illustration Turning that displays the data included Turning.SLDASM in the CAM-Part named Turning. CAM.SLDPRT The Turning.prt file is DesignModel.SLDPRT located in the SolidCAM directory. The Turning subdirectory contains all the data generated for the CAM-Part. SolidCAM copies the original SolidWorks model to the Turning subdirectory and creates a SolidWorks assembly that has the same name as the CAM-Part ( Turning.sldasm). There are two components in this assembly: • DesignModel.sldprt – a copy of the SolidWorks model file. • CAM.sldprt – a file that contains SolidCAM Coordinate System data and geometry data. The SolidCAM CAM-Part uses the assembly environment of SolidWorks. This enables you to create auxiliary geometries (e.g. sketches) without making changes in the original design model. You can also insert some additional components into the assembly file such as stock model, CNC-machine table, clamping and other tooling elements. The New Turning Part dialog box is displayed. Click The Turning Part Data dialog box is displayed.

Choose CNC-Machine

Define the CNC-machine controller. Click the arrow in the CNC-Machine area to display the list of post-processors installed on your system. In this exercise, choose the T_4X_Haas_ST30_HaasCNC CNC-Machine from the list.

4.

Define the Coordinate System

Click Define in the CoordSys area of the Turning Part Data dialog box to define the Machine Coordinate System.

The Machine Coordinate System defines the origin for all machining operations on the CAM-Part. It corresponds with the built-in controller functions. It can be used for various clamping positions in various operations on the CAM-Part. Usually Turning CNC-machines have only one machine Coordinate System; its Z-axis is the rotation axis of the spindle. The Machine Coordinate System enables you to perform all turning operations.

Z-axis

The CoordSys dialog box enables you to define the location of the Coordinate System and the orientation of the axes.

16


You can define the position of the Coordinate System origin and the axes orientation by selecting model faces, vertices, edges or SolidWorks Coordinate Systems. The geometry for the machining can also be defined directly on the solid model. SolidCAM offers the following methods of CoordSys definition: • Select Face

This method enables you to define a new CoordSys by selecting a face. The face can be planar or cylindrical/conical. For planar faces, SolidCAM defines CoordSys with the Z-axis normal to the face. For cylindrical or conical faces, the Z-axis of the CoordSys is coincident with the axis of revolution of the specified cylindrical/conical surface. • Define

This method enables you to define the CoordSys by picking points. You have to define the origin and the directions of the X- and Y-axes. • Select Coordinate System

This method enables you to choose the SolidWorks Coordinate System defined in the design model file as the CoordSys. The CoordSys origin and the orientation of the axes is the same as in the original SolidWorks Coordinate System. • By 3 points (associative)

This method enables you to define the CoordSys Origin and axes by selecting any three points. Choose the High precision option. High precision

When the High precision check box is selected, the Coordinate System is defined using the faceted model, which results in more precise definition, but may take more time to generate. When this check box is not selected, the Coordinate System is defined using CAD tools without facetting

17

Choose the Center of revolution face option. With this option, the origin is placed automatically on the axis of revolution face. With the Select Face mode chosen, click on the model face as shown. The Z-axis of the CoordSys is coincident with the axis of revolution. Note that the CoordSys origin is automatically defined on the model back face and the Z-axis is directed backwards. Click Change to opposite.

This button enables you to change the Z-axis direction to the opposite along the revolution axis.

Now the CoordSys origin is located on the front face of the model, and the Z-axis is directed forward along the revolution axis. Confirm the selection by clicking Finish. The Coordinate System is defined. The Turning Part Data dialog box is displayed again.

Define the Stock model

For each Turning project, it is necessary to define the boundaries of the stock material (Stock) used for the CAM-Part. Click the Stock button. The Stock dialog box is displayed. This dialog box enables you to define the Stock model of the CAM-Part to be machined.

19

The following methods of Stock definition are available: • Cylinder

This option enables you to define the Stock boundary as a cylinder surrounding the selected solid model. You can define the cylindrical stock by specifying Offsets of the cylinder faces from the selected solid body or coordinates of its boundaries relative to the CAM-Part Coordinate System. The Add to CAD model button enables you to add a 3D sketch of the cylinder stock to the CAM component of the part assembly. • Box

This option enables you to define the Stock boundary as a box surrounding the selected solid model. When you click on the solid body, SolidCAM generates a 3D box around it. This box defines the geometry of the Stock. • Revolved boundary around Z

This option enables you to define the Stock boundary as a wireframe geometry chain using one of the model sketches. When the chain is selected, perpendiculars are dropped from its end points to the axis of rotation to define the material boundary. The Revolved boundary around Z option enables you to define only one chain, either opened or closed. When more than one chain is defined, the error message is displayed. Selected chain

20

2. CAM-Part Definition • 3D Model

This method enables you to define the Stock boundary by selecting the 3D Model of the stock. SolidCAM automatically generates a sketch that contains the envelope of the selected solid body. The Stock boundary is defined automatically on this sketch. Envelope

Consider the revolution body surrounding the specified solid bodies. The section of this revolution body by the ZX-plane of the Coordinate System is the envelope. The envelope line is the profile of the part that has to be turned in order to obtain the model geometry.

to confirm the Stock selection. Define the Target model

Now you have to define the Target model.

The Target model is the final shape of the CAM-Part after the machining. It is used for gouge checking in the Solid simulation. During the Target model definition, SolidCAM creates an Envelope sketch in the CAM component of the CAM-Part assembly. This sketch contains the geometry automatically generated by the Envelope function of SolidCAM. This function creates the envelope line of the specified solid bodies. Consider the revolution body surrounding the solid body. The section of this revolution body by the ZX-plane of the Turning Machine CoordSys is the envelope. This envelope is a profile of the part that has to be turned in order to create the model geometry.

Section

The Envelope function takes into all external model faces as well as the internal faces. The geometry created by the Envelope function can be used for the Geometry definition in SolidCAM operations. The Mirrored Envelope option generates the envelope sketch mirrored about the Z-axis in the ZX-plane. This option is applicable for machines with lower turret. In addition to the Envelope, SolidCAM enables you to generate a sketch containing a Section of the Target model by the ZX-plane. The Section sketch is created in the CAM component of the SolidCAM Part Assembly. In the Turning Part Data dialog box, click the Target button. The Target dialog box is displayed. This dialog box enables you to define a 3D Model for the Target. Click on the solid body. The wireframe model is displayed.

23

Set the Facet tolerance to 0.01. This parameter defines the accuracy of the triangulation of the stock model, target model and fixtures. The triangulated models are used later in the tool path simulation. The tighter is the tolerance, the better is the performance of the simulation. . Confirm the dialog box with In the process of the Target model definition, SolidCAM creates the Envelope sketch in the CAM component of the CAM-Part assembly. The Envelope sketch is used later for the machining geometry definition.

Define the Coordinate System

Definition of the Machine Coordinate System is a mandatory step in the process of CAM-Part definition. This step can be performed automatically if the corresponding option is chosen in SolidCAM settings. The Machine Coordinate System defines the origin for all machining operations on the CAM-Part. It corresponds with the built-in controller functions and can be used for various clamping positions in a variety of operations on the CAM-Part. The Machine Coordinate System #1 (Position #1) can be used for turning operations as well as for all types of milling operations. In the Turning mode, SolidCAM uses the Turning Coordinate System created by rotating of the Machine Coordinate System #1 (Position #1) around the Z-axis.

Geometry

Coordinate System

The axes orientation for the Turning Coordinate System are defined in the CoordSys item of the submachine in the Machine ID file of the chosen CNC-controller. At the stage of operation definition, you will need to make sure that you choose an appropriate submachine to generate the correct GCode. Click the Coordsys button in the Coordinate System area of the Mill-Turn Part Data dialog box to define the Machine Coordinate System.

The CoordSys dialog box enables you to define the Coordinate System location and the orientation of the axes. You can define the position of the Coordinate System origin and the axes orientation by selecting model faces, vertices, edges or SolidWorks Coordinate Systems.

30


SolidCAM enables you to define the CoordSys using the following methods: • Select face

This method enables you to define a new CoordSys by selecting a face. The face can be planar or cylindrical/conical. For planar faces, SolidCAM defines CoordSys with the Z-axis normal to the face. For cylindrical or conical faces, the Z-axis of the CoordSys is coincident with the axis of revolution of the specified cylindrical/conical surface. When the High precision check box is selected, the Coordinate System is defined using the faceted model, which results in more precise definition but may take more time to generate. When this check box is not selected, the Coordinate System is defined using CAD tools without facetting. • Define

This method enables you to define the CoordSys by picking points. You have to define the origin and the directions of the X- and Y-axes. • Select Coordinate System

This method enables you to choose the SolidWorks Coordinate System defined in the design model file as the CoordSys. The CoordSys origin and the orientation of the axes is the same as in the original SolidWorks Coordinate System. • Normal to current view

This option enables you to define the Coordinate System with the Z-axis normal to the model view you are facing on your screen. The CoordSys origin will lie in the origin of the SolidWorks Coordinate System, and the Z-axis will be directed normally to the chosen view of the model. • By 3 points (associative)

This option enables you to define the CoordSys Origin and axes by selecting any three points.

Define the CoordSys data

The CoordSys Data dialog box enables you to define the Coordinate System values and machining levels such as Tool start level, Clearance level, Part upper level, etc. CoordSys Data dialog box

The MAC Number defines the number of the CoordSys in the CNCmachine. The default value is 1. If you use another number, the GCode file contains the G-function that prompts the machine to use the specified number stored in the controller of your machine.

33

The Position field defines the sequential number of the Coordinate System. For each Machine Coordinate System, several Position values can be defined for different positions; each such Position value is related to the Machine Coordinate System. • X shows the X-value of the CoordSys. • Y shows the Y-value of the CoordSys. • Z shows the Z-value of the CoordSys. The Create planar surface at Part Lower level option enables you to generate a transparent planar surface at the minimal Z-level of the part so that its lower level plane is visible. This planar surface provides you the possibility to select points that do not lie on the model entities. It is suppressed by default and not visible until you unsuppress it in the FeatureManager Design tree. The Levels section is divided into three parts: Planar, Radial and Rear. The Levels: Planar section displays levels for milling from the positive Z-direction. The Levels: Radial section contains a set of machining levels describing the virtual cylinders situated around the Z-axis. Tool Z-level Tool Start Level Clearance level Part Upper Level CoordSys

These tabs contain the following parameters: • The Tool Z-level is the height to which the tool moves before the rotation of the 4/5 axes to avoid collision between the tool and the workpiece. This level is related to the CoordSys position and you have to check if it is not over the limit switch of the machine. It is highly recommended to send the tool to the reference point or to a point related to the reference point. • The Tool start level defines the Z-level at which the tool starts working. • The Clearance level is the Z-level to which the tool moves rapidly from one operation to another (in case the tool does not change). • The Part upper level defines the height of the upper surface of the part to be machined. • The Part lower level defines the lower surface level of the part to be machined.

The Translation Data option enables you to set the Shift and Rotation values. Shift is the distance from the Machine Coordinate System to the location of the Position in the coordinate system and the orientation of the Machine Coordinate System. Rotation is the angle of rotation around the main axes X, Y and Z. In the Mill-Turn module, facial and radial milling is performed using the same Coordinate System. But since the part levels used for facial milling are measured along the Z-axis, whereas those used for radial milling are measured around the Z-axis, the CoordSys data must be defined separately. The Plane box defines the default work plane for the operations using this CoordSys, as it is output to the GCode program. In the SolidCAM CAM module, you must always work on the XY-plane. Some CNC-machines, however, have different axes definitions and require a GCode output with rotated XY-planes. Confirm the CoordSys Data dialog box with

4.1 Basic Turning SolidCAM enables you to perform the following types of Turning operations.

Turning Operation types

Face Turning

Cutoff

Turning

Trochoidal Turning

Drilling

Balanced Rough

Threading

Manual Turning

Grooving

Sim. tilted turning

Angled Grooving

Face Turning Operation This operation enables you to perform turning of facial profiles. The principal working direction is the X-axis direction.

Turning Operation This operation enables you to turn a longitudinal or facial profile. The resulting tool path can either use the turning cycles of the CNC-machine, if they exist, or it can generate all the tool movements. If the tool movements are generated by the program, then minimum tool movements length is generated taking into the material boundary in the beginning of the particular operation. The profile geometry is adjusted automatically by the program, if needed because of the tool shape, to avoid gouging of the material.

48

4. Turning Operations

Drilling Operation This operation enables you to perform a drilling action along the rotation axis. There is no geometry definition for this type of operation since it is enough to define the drill start and end positions.

Threading Operation This operation enables you to perform threading. The threading can be either longitudinal (internal or external) or facial. This operation can be used only if the CNC-machine has a thread cycle. SolidCAM outputs the tool path for the threading exactly with the same length as the defined geometry without any checking for material collision.

Grooving Operation This operation enables you to perform a groove either on a longitudinal geometry (internal or external) or a facial geometry. The resulting tool path can either use a single machine cycle, generate all the tool movements (G0, G1) or generate several machine cycles.

Angled Grooving Operation This operation enables you to perform inclined grooves. The geometry defined for this operation must be inclined relative to the Z-axis of the CAM-Part Coordinate System. The Tool angle parameter enables you to adjust the angle of the tool cutting the material.

49

Cutoff Operation This operation enables you to perform cutoff machining. This operation is used to cut the part or to perform a groove whose width is exactly the same as the tool width. The cutting can be performed using CNC-machine cycles; chamfers and fillets can also be generated.

Balanced Rough Operation This operation enables you to work with two tools performing roughing cuts at the same time. The Master submachine and Slave submachine should include the same Table.

Manual Turning Operation This operation enables you to perform turning according to your own geometry regardless of a stock model, target model, or envelope. The Reverse cutting path option enables you to machine undercuts effectively.

Sim. tilted turning This operation enables you to perform machining of curveshaped tool paths using tilting capabilities of tools with round insert. The tool tilting is defined by specifying lines that indicate the tool vector change. This operation is useful for machining of undercut areas in a single machining step.

For more detailed explanation on the Turning operations, refer to the SolidCAM Turning Online Help.

Machine Setup

The Machine Setup definition is an optional step in definition of CAM-Parts that contain Turning operations. Using the Setup feature, you can define the fixtures and their location relative to the Coordinate Systems associated with certain submachines. This unified representation of all setup data allows you to get a more realistic picture during simulation and check possible collisions between the cutting tools and fixtures. At this stage, you have to define a fixture that helps to prevent a possible collision of tools during machining. The Fixture column enables you to choose or define a fixture to be used with the specified submachine. To define the fixture, double-click the cell, click the arrow and choose . The Model dialog box is displayed. This dialog box enables you to define the fixture geometry. Make sure that the Chuck (Standard) option is chosen in the Defined by section.

This section enables you to define how the clamping device will be attached to the workpiece. Selecting the Mirrored check box moves the fixture on the back spindle.

52

4. Turning Operations Chuck position

The chuck positioning is defined with the Clamping diameter (CD) and Axial position ( Z ) parameters relative to the stock end face: The Clamping diameter (CD) and Axial position ( Z ) parameters can be defined by picking on the model. When the model is picked, SolidCAM measures the X- and Z- distances from the CoordSys origin to the picked positions and displays the values in the corresponding edit boxes. The default Chuck position is defined on the edge of the stock envelope created during the Stock model definition. The Clamping diameter is 94, and the Axial position is -92. Now you need to define the dimensions of the chuck. Chuck sizes library

SolidCAM enables you to define and store fixtures as libraries for reuse in fixture definition. Click the Take from library button to open the Fixture library dialog box. This dialog box enables you to create and manage the fixture library. Jaws parameters

•

The Jaw width (JW) parameter defines the overall width of a single jaw.

Turning geometry can be defined by selecting wireframe elements or by picking solid model entities such as faces, edges and vertices. The following geometry definition options are available: • Wireframe

This option enables you to define the turning geometry by wireframe geometry selection. • Solid

This option enables you to define the turning geometry by selecting model entities such as faces, edges, vertices, origin and sketch points. When model entities are picked, SolidCAM automatically defines the geometry on the envelope/section segment corresponding to the selected model elements. You have to define the machining geometry for the external roughing operation using the Envelope sketch. The sketch was automatically generated in the Target model definition process described in Exercise #1. Click the New icon ( ). The Geometry Edit dialog box is displayed in the SolidWorks PropertyManager area. This dialog box enables you to define and edit geometry chains. SolidCAM enables you to choose the mode of the geometry selection in the Chain section of the Geometry Edit dialog box. Chain options

You can define the geometry by selecting edges, sketch segments and points on the contour. The following options are available: • Curve

You can create a chain of existing curves and edges by selecting them one after the other. Associativity:

SolidCAM keeps the associativity to any edge or sketch entity. Any change made to the model or sketch automatically updates the selected geometry.

56


The Curve option offers the following options: Up to Entity: The

chain is selected by specifying the start curve, the direction of the chain and the element up to which the chain is created. SolidCAM enables you to choose any model edge, vertex or sketch entity to determine the chain end.

When the end item is chosen, SolidCAM determines the chain according to the chosen selection mode (Tangent propagation, Constant Z Propogation). The chain selection is terminated when the selected end item is reached. If the chosen end item cannot be reached by the chain flow, the chain definition is terminated when the start chain segment is reached. The chain is automatically closed. Tangent propogation: A tangent entity following the current one and not located at the same Z-level is chosen.

You are required to enter a positive and negative Z-deviation into the Delta Z Tolerance edit box. Only entities within this range are identified as the next possible entity of the chain. Constant Z propogation:

• Point to point

This option enables you to connect specified points; the points are connected by a straight line. Associativity:

SolidCAM does not keep the associativity to any selected point. SolidCAM saves the X-, Y- and Z-coordinates of the selected points. Any change made to the model or sketch does not update the selected geometry. • Arc by points

This option enables you to create a chain segment on an arc up to a specific point on the arc. Associativity:

SolidCAM does not keep the associativity to any selected arcs by points. SolidCAM saves the X-, Y- and Z-coordinates of the selected points. Any change made to the model or sketch does not update the selected geometry. 57

Make sure that the default Curve mode is chosen. Unselect the check boxes of Up to Entity, Tangent propagation and Constant Z Propagation. Select the sketch segments as shown. The order of the geometry selection is important, since it defines the direction of machining. Operations in SolidCAM use the direction of the chain geometry to calculate the tool path. The arrow at the start point of the chain indicates the direction of the chain. In the Chain section of the Geometry Edit dialog box, choose the Point to point option. This option enables you to connect the specified points with a straight line. Click on the sketch point as shown. The linear geometry segment is defined.

The number of revolutions per minute is calculated automatically according to the actual diameter. Using this option, you can maintain the constant cutting speed along the tool path. In the areas of the smallest diameter, the number of revolutions is greater and vice versa.

Under Spin, choose the V(m/min) option in the Spin rate and Spin finish sections. Set the cutting speed value of 240 for the Spin rate and the Spin finish. Set the Reference diameter value to 100. Set the Min. Spin (rpm) value to 100. Set the Max. Spin (rpm) value to 3000. With this value, SolidCAM limits the number of revolutions per minute. The gear drop down list provides you the list of gear units as defined in the VMID file. When V(m/min) option is used in either Spin rate or Spin finish sections, the Auto Gear-switching section is enabled. This allows you to override the gear units and define the min. and max. rpm in order to maintain a constant surface speed. The Reference diameter parameter allows you to define the value used for calculating the minimum rpm. The Min. and Max. spin parameters allow you to define the min and max spin values of the current gear unit. Selecting the Stay in gear limits check box, uses the Min. and Max. spin values according to the defined machine gear unit. If you select the Auto Gear-switching check box, the gear drop down list is not available for use. 76

4.3 Advanced Turning: Partial machining This functionality s rough, semi-finish and finish machining of long turning parts. In long turning parts the machining of the whole geometry all at once might cause problems due to the deformation of the workpiece under the cutting tool. Partial machining provides the capability to machine the geometry by dividing it into several segments. Segment #5

Segment #2

Segment #1

123

Exercise #9: Long Shaft Machining The following exercise illustrates SolidCAM functionality of Partial machining in turning operations performed on the Long Shaft part.

1.

Load the part file

Load the Exercise9.prz file located in the Exercises folder. This file contains the pre-machined part with two Turning operations in which the machining of the front face and the first step is performed. 2.

Machine the first segment of the geometry

Add a new Turning operation in SolidCAM Manager. Define the full machining geometry as shown.

This geometry will be machined in several segments in a number of Turning operations. In the Part Tool Table, choose the Ext.rough tool (Tool #2) used in the previous operation. In the Geometry page, select the Partial machining check box. Click the Data button that becomes available. The Partial Machining dialog box is displayed, and the geometry chain is highlighted on the model.

124


This dialog box enables you to define the geometry segment that will be machined in the operation and related parameters such as its initial and final points, distance and approach/retreat data.

First point/Second point

The First point and Second point sections enable you to define the profile segment that will be machined in the operation and the parameters of the tool approach/retreat movements. The generated partial cutting is performed between the first and second points; the cutting direction is determined according to the Profile direction option state.

Second point

First point

SolidCAM automatically generates the approach and retreat es at the First point and Second point according to the machining direction. In the illustration above, the approach movement is performed at the First point and the retreat movement is performed at the Second point.

125

The approach/retreat consists of an arc tangential to the partial machining geometry at the First/Second point, and a line connected to the arc. The line direction is automatically chosen according to the Tool type, Tool tip angle and Safety angle parameters. By default, the Distance along axis parameter located in the First point and Second point sections displays the minimal/ maximal Z-coordinate of the geometry. Since the first segment to be machined starts at the beginning of the geometry, do not change the default value of this parameter for the First point. Pick the final point of the segment to be machined by clicking approximately in the middle of the edge as shown.

The Distance along axis value for this point is calculated automatically (-135.61) and displayed in the X,Y,Z dialog box. Round it down manually to -135. When the point has been picked, SolidCAM calculates the Distance along axis and Diameter values for the picked point and displays them in the X,Y,Z dialog box. The Distance along axis parameter displays the distance from the CoordSys to the First/Second point along the Z-axis. When the Pick option was used, the value is calculated automatically. It can also be used as an alternative to the Pick option to define the First/ Second point locations. Even if the Pick option was already used, you can edit the value received from the model and thus change the First/Second point locations.

126


The Diameter parameter displays the value of the part diameter at the specified location and is calculated automatically according to the geometry and the Distance along axis value. When there are several Diameter values for a single Distance along axis value, SolidCAM chooses the maximal Diameter value determined. Diameter

First point

X CoordSys Z Distance along axis Distance along axis

Now you need to define the approach and retreat parameters. Approach/Retreat parameters

The Radius parameter defines the radius of the approach/ retreat arc tangential to the profile at the First/second point. The Line length parameter defines the length of the straight line tangential to the arc. The direction of the approach/ retreat lines, connected to the approach and retreat arcs, is chosen according to the Tool type. Retreat line length

Retreat radius

Second point

Approach radius

Approach line length

When the approach/retreat lines are located inside the Material boundary of the pre-machined stock, SolidCAM automatically extends them till the Material boundary.

Approach line length

Second point

Make sure that the Radius value for both First point and Second point is 0.5. It must be equal to the tool nose radius (Ra). Select the Modify point to avoid collision check box for both First point and Second point.

128

4. Turning Operations Modify point to avoid collision

When this check box is selected, automatic modification of the defined First and Second points is performed according to the geometry. The point modification enables you to avoid possible collisions during the approach and retreat movements. When the First point is not modified, the approach is performed as follows:

Second point

First point

The possible collision during the approach movement can be avoided by the automatic point modification.

Second point

First point

Note the Modify contour to avoid collision check box at the bottom of the Partial Machining dialog box.

129

Modify contour to avoid collision

This check box enables Non-modified contour you to perform the modification of the partial machining geometry. When this check box is selected, the geometry modification is performed according to the tool shape. The modification Modified contour enables you to avoid possible collisions between the tool and the geometry during the machining. During the geometry modification, the machining geometry is changed in areas where the possible collisions are detected. The geometry is changed taking into the tool shape. The Modify contour to avoid collision check box affects only the finish and semi-finish tool path when the Profile option is chosen for the Work type. When the Rough option is chosen, the geometry modification is automatically performed, irrespective of the state of the Modify contour to avoid collision check box. Click the Show button to check the machining geometry and the updated partial geometry between the First point and the Second point with the tangential arcs and connected lines.

130


Confirm the Partial Machining check box by clicking the OK button. Click the Save & Calculate icon in the Turning Operation dialog box. Simulate the tool path in the Turning mode. 3.

Machine the second segment of the geometry

Click the Save & Copy icon in the Turning Operation dialog box. An additional Turning operation is added in SolidCAM Manager. This operation is a copy of the previous one and contains the same geometry and tool data. Define the Partial machining parameters to machine the next geometry segment. Switch to the Geometry page. Check the Partial Machining check box and click on the Data button. The Partial Machining dialog box is displayed. Define the first point of the segment in such way that there will be an overlap between the surface machined in the previous operation and the one to be machined. In the previous operation, the length of the machined segment was 135 mm, i.e. the Distance along axis value for the Second point was -135. Set the Distance along axis value for the First point to -134 to perform the 1 mm overlap in the machined surface. Click the Pick button in the Second point section. Pick the point as shown.

131

The Distance along axis value for the Second point is calculated: -250.

Confirm the Partial Machining dialog box. Click the Save & Calculate icon in the Turning Operation dialog box. Simulate the tool path in the Turning mode.

4.4 Turning on Mill-Turn CNC Machines SolidCAM s all types of Mill-Turn CNC-machines. The Mill-Turn CAM-Part is not strictly associated with the only type of machine on which it is intended to be manufactured. In the Mill-Turn module, the flexibility of CAM-Part definition in of CNC-machine usage enables you to easily change the type of machines for parts. The type of the chosen CNC-machine though applies certain restrictions on the technology: for example, if your programming is intended for a 3-axis CNC-machine that s the XZC coordinates, the tool path is not supposed to contain movements along the Y-axis (except for the movements that can be translated into the available axes of the machine). Such functionality enables you to create a required machining technology and then to adapt it for usage on a certain CNC-machine. All types of Mill-Turn CNC-machines enable you to perform turning operations.

Profile Operation You can mill on or along a contour. The profile geometry can be open or closed. In profile milling you can optionally use tool radius compensation to the right or to the left side of the geometry. SolidCAM offers two types of profiling: • Milling a single profile to the specified constant or variable depth in one step or in several defined down steps. • Concentric profiles to the specified constant or variable depth; this type of profiling generates several concentric profiles that start from the defined clear offset distance from the profile, and finish on the profile geometry, thus clearing the area around the profile to a constant depth.

Contour 3D Operation This operation enables you to utilize the power of the 3D Engraving technology for the 3D contour machining. In this operation, SolidCAM enables you to prevent the gouging between the tool and the 3D contour.

Pocket Operation In pocket milling, you remove material from the interior of a closed geometry. SolidCAM offers two types of pocketing: • Pocket without islands. When a profile geometry consists of one or more profiles and none of them are enclosed or intersect with one another, each is milled as a separate pocket without islands. • Pocket with islands. When a profile geometry consists of several profiles, any profile that is enclosed or intersects with another profile is treated as an island. You can define an unlimited number of islands within a single pocket.

Drilling Operation This operation enables you to perform 2D and 3D drills and other canned drill cycles. SolidCAM s the canned drill cycles provided by your particular CNC-machine such as threading, peck, ream, boring, etc. If your CNC-machine has no canned drill cycles of its own, they can be defined using the General Pre- and Postprocessor program (GPPTool). With 3D drills, SolidCAM takes into the solid model geometry. The program uses the holes prepared in this operation for the descent during 3D Model roughing.

161

Thread Milling Operation This operation enables you to generate a helical tool path for the machining of internal and external threads with thread mills.

Slot Operation This operation generates a tool path along the centerline to the right or to the left of one or more profiles. Two types of slots can be defined: the Slot with constant depth operation machines the slot in several steps until the final depth is reached. In Slot with variable depth, the depth profile is also defined by a 2D section. The slot can be pre-machined using rough and semi-finish cycles. The finish cut produces a tool path according to the specified scallop height on the floor of the slot. With available parameters for the right and left extension and the side step, you can mill a slot wider than the tool diameter. T-Slot Operation This operation enables you to machine slots in vertical walls with a slot mill tool.

Translated Surface Operation A translated surface is generated by moving a section along a profile geometry. Limit geometries can be projected on the translated surface. You can machine the resulting translated surface inside, outside or along the limit geometry.

162


ToolBox Cycles ToolBox sub-operations are a set of 2.5D Milling operations, and each one of these operations is intended for a specific machining case. For example, a number of operations cover different strategies of the counterbore machining. Each operation provides you with a specific machining strategy optimal for a particular machining case.

Engraving Operations You can mill text or any other profile on a 2D or 3D geometry. The profile is projected on the surface, engraving the contour at a specified depth.

Pocket Recognition Operation This operation enables you to recognize the pocket features on the solid model and perform the machining of these features.

Chamfer Recognition Operation This operation recognizes automatically chamfer features at the target model and creates the necessary machining.

163

Drill Recognition Operation This operation performs powerful drill feature recognition and automatic Drill geometry creation using the AFRM module functionality. This operation enables you to handle separate sets of Milling levels for each drill position. The initial values of the Milling levels sets are automatically recognized from the model; they can be edited by the . HSS Operation SolidCAM HSS module is a high speed surface machining module for smooth and powerful machining of localized surface areas in the part, including undercuts. It provides easy selection of the surfaces to be machined, with no need to define the boundaries. It s both standard and shaped tools. 3D HSR/ 3D HSM Operation SolidCAM HSR/HSM module smooths the paths of both cutting moves and retracts wherever possible to maintain a continuous machine tool motion – an essential requirement for maintaining higher feed rates and eliminating dwelling. The retracts to high Z-levels are kept to a minimum. Angled where possible, smoothed by arcs, retracts do not go any higher than necessary, thus minimizing air cutting and reducing machining time. The result of HSM is an efficient, smooth, and gouge-free tool path. Sim. 5 Axis Operation This operation enables you to perform simultaneous 5-axis machining. 5-axis machining strategies enable the use of SolidCAM for machining of complex geometry parts such as mold cores and cavities, aerospace parts, cutting tools, cylinder heads, turbine blades and impellers. SolidCAM enables collision checking between the tool and the machine components.

164


Multiaxis Roughing Operation This operation creates a multiaxis tool path used to rough out pocket shaped geometries. You can specify the inputs for floor, wall and ceiling surfaces which are used by SolidCAM to create the roughing tool path. SWARF Machining Operation SWARF (Side Wall Axial Relief Feed) machining is one of 5-Axis Simultaneous milling operations. The purpose of the operation is to produce the target surface with only one cut, while the whole flute length of the tool is used.

Multiaxis Drilling Operation This operation enables you to machine a series of drills that have different orientations.

Contour 5-Axis Machining Operation This machining strategy tilts the tool along a chained 3D profile drive curve, while aligning the tool axis according to defined tilt lines, making it ideal for generating 5-axis tool path for deburring and trimming.

3 to 5 axis Conversion In some machining cases, there is a need to perform machining of 3D parts using the 5-axis capabilities. For example, 3D machining of deep cavities requires the use of tools of great length, which can cause tool breakage; the same cavities can be machined using a tool of smaller length while tilting this tool to follow the same tool path.

165

Rotary Machining 4 axis This operation is designed to generate rotary tool path to mill parts on a 4-axis machine. It can be used to mill cylindrical parts like bottle molds and core, electrodes, and wood work. The tool paths are directly calculated on 3D geometry and not wrapped around. Port Machining Operation This operation is an easy-to-use method for machining ports with tapered lollipop tools, and has collision checks for the entire tool. It provides both roughing and finishing tool paths to make ports from castings or billet.

Multiblade Machining Operation This operation easily handles impellers and bladed disks, with multiple strategies to efficiently rough and finish each part of these complex shapes. Multibladed parts are used in many industries and this operation is specifically designed to generate the necessary tool paths for the different multiblade configurations.

2D iMachining / 3D iMachining SolidCAM iMachining is an advanced technology of high speed machining that generates optimized tool paths, efficient cutting and high material removal rates, while reducing machining time and tool wear. The iMachining Technology Wizard enables you to define the optimum cutting conditions for sustainable high speed machining. Using the cutting conditions produced by the Wizard, the iMachining Tool Path Generator calculates all the tool paths necessary to efficiently produce the target geometry from the given stock geometry.

5.1 Using MCO on Mill-Turn CNC-machines SolidCAM s the use of the back spindle in the Mill-Turn module. This functionality enables you to use the back spindle of your CNC-machine for Turning and Milling machining with the part clamped in the main or back spindle. The part is transferred between the spindles, thus enabling you to complete the part machining from both sides in a single setup. Each milling or turning operation can be performed with the part clamped in the main or back spindle. Operation sequence #1: General use There are two optional stages in this operation sequence: 1. SolidCAM Operations with Main spindle. At this stage, only the main spindle is used for milling and turning operations; this is the standard way of working in SolidCAM when the back spindle does not exist.

2. SolidCAM Operations with Back spindle. At this stage, the operations are performed with the back spindle only.

181

Operation sequence #2: Optimized tool use SolidCAM enables you to define a combined sequence of operations that uses intermittently the main and back spindles. Each operation in the sequence is related either to the main or to the back spindle. The Machine Control Operation enables you to define the transfer of the machined part between the main and back spindles. In this sequence, the combined operations with the main and back spindle use enable you to avoid unnecessary tool change (in cases when the same tool can work with the main and back spindles). In the beginning or end of all operations, the finished part is ejected from the back spindle and the partly machined part is transferred from the main spindle to the back spindle.

Channel Synchronization

7

SolidCAM’s Channel Synchronization operation enables you to synchronize operations in multi-channels machines and organize the order of operations. Using the operation of channel synchronization, you can finish machining a part in the following ways: • In lesser time by simultaneously machining two sides of a part. For example, front of a part on main spindle and back of the same part on back spindle utilizing either upper turret or lower turret or both. The advantage is you do not have to keep the spindle idle, waiting for the primary operation to finish and the secondary one to start. • Simultaneously performing machining processes on both the spindles. • In Milling operations, where there is only one spindle, the channel synchronization operation can be used to synchronize the tool in such a way that without going back to the home position, the tool can finish machining operation on one part and immediatelty start the other operation on the second part. 1.

Open the Channel synchronization dialog box

Right click Setup > Channel synchronization.

The Channel Synchronization window opens.

In the right pane, you can see the RGB values of the selected color displayed in the columns. Click in the column next to Up_TR. Click the ... icon. The Color window displays. Define the color in the same way as you defined it for Synchronization label. Click the Save button and close the MACHINE ID EDITOR window. The color you define here, will be applied when you select the Color operations by Turret button in the Channel Synchronization window. You can define the color for lower turret, main spindle, back spindle, and workpieces in the same manner. The color you define here, will be applied when you select the Color operations by Table or Color operations by Workpiece buttons in the Channel Synchronization window respectively.

326


7.3 General Rules of Channel Synchronization The following rules apply to the channel synchronization operation: •

•

When you right click Setup and select Channel Synchronization from the submenu, the synchronization order you see is according to the operations defined in the CAM Tree. The order of the operations defined in the CAM Tree cannot be changed in the synchronization window for the same turret. If you want to change the order, you must change the sequence in the CAM Tree. To start sequencing the operations on the back spindle, right click the first operation defined on the lower turret and click Add new Workpiece.

The Add new Workpiece operation can be defined on the operation of your choice to start the machining from there. However, it is a general practice to add it on the first operation defined on the lower turret. You can split the CAM Tree order to create separate Workpieces (Machining processes) for continuous machining process on CNC machine (loop machining). •

•

•

•

In the Channel Synchronization window, Setup should always be the first operation. Setup is loading new Stock, according to the Setup table. When you open the Channel Synchronization window, and if the Setup operation is not seen as the first operation, then you must drag and place is at the top of the operations as the defined stock must be visible in the first operation. The operation of stock release cannot be moved below the part transfer operation. However, it can be moved after the last operation on back spindle in the Channel Synchronization window. Stock release is a machine control operation with Release Stock command which deletes the stock from the active table. The operation of stock transfer is a machine control operation with two or more tables involved. As a result of this operation, the stock changes the holding Table. You can achieve this by Manual Part Transfer or Close on Stock command. The MCOs cannot be synchronized if same axis is used in both the channels. If you try to synchronize such an operation, an error message is displayed stating same axis is used in both the channels. 327

•

Each operation in the Channel Synchronization window is connected to one table in the following manner: • In non MCO operations it is connected to the Table used in operation Submchine. • In MCO operations without Stock Management it is connected to the current table. • In the setup and stock release operations, it is connected table that is used for these specific operations. • In the part transfer operation, it is related to the table that was connected to the stock before the part transfer operation.

•

To move the operation and change its place in the Channel Synchronization window, drag the operation and drop it on the lable where you want to place it. For example, in the below image, the highlighted operation in black color is dragged and placed on the lable to change its place.

7.4 Working with the operation of Channel Synchronization 6.

Labels and drive units

Label is a defined pause you can apply between two operations if a collision is detected. The labels give you information about all the channels are involved in the operation. The first label in the synchronization widow is always numbered 1. The last label is always the largest and takes into all the channels involved. For example, if you are working on a three channel machine, you can apply some labels to two channels, but the last label will be applied to all three channels. The labels above and below the Balanced Rough operation are automatically added and cannot be deleted. For example, when you right click on the label that is above or below the Balanced Rough operation, the option of deleting the lable is not available to select.

328


When two operation are synchronized using the same drive unit, you can define which channel has control over it. If you want to change the control from upper turret to lower turret, right click the Drive Unit icon and select Make Drive Unit control to ‘LW_TR’ Channel to transfer the control from upper turret to lower turret.

In the image below, the control is transferred to the lower turret and now selecting the drive unit icon gives you the option of transferring the control to the upper turret.

In the Balanced Rough operation, the drive unit control cannot be changed as while defining the operation, master and slave submachines are defined. You can change the controls by editing the balanced rough operation in the CAM-Tree. You can use the same Drive Unit by more than one channel at the same time only if it is a Shared Drive Unit. You need to keep in mind the following things while using a shared drive unit: • In Milling operations, the Drive Unit must have same RPM and rotation direction. • In Turning operations, the Turning Station, connected to Drive Unit must have same RPM, rotation direction, and same Spin Type.

329

7.

Removing the clash in operations

When two operations cannot be synchronized, or are arranged in such a manner that they clash with each other, they are highlighted in red color. Click on the red box to see with which operation the current operation is clashing. Select both the operations and add a label as per your requirement i.e. whether you want to synchronize the operations start to start, start to end or end to end. In the below image, two operations that are clashing (highlighted using dark blue color) are selected, and on the ribbon available on the Channel Synchronization window, the buttons of Synchronize selected operations start to start, Synchronize selected operations start to end, and Synchronize selected operations end to end are highlighted.

8.

Axes sharing and control

In the Channel Synchronization window, you can see a number of axes displayed in front of each operation. The axes represented with black color, are used in the current operation. The axes represented by grey color, and italics are not used in the current operation. However, you can see them in front of the operation because all these axes are available on that channel.

You can use the same axis on two channels at the same time, only if they are shared axis. The switching and moving of axis between channels can be done only at the label level.

330


Swap axis option is available on an axis which is not used in the operation and is synchronized end to end with another operation. Click on Swap Axis With option to swap the current axis with the axis available in the Swap Axis With list.

The exercises described above explain the general rules and features of the Channel Synchronization operation. You can synchronize the operations in the way you consider is best to utilize the machines for maximum output and minimum machining time. Channel Synchronization on Single Channel Machines On Milling machines, where there is only one spindle, SolidCAM’s Channel Synchronization operation can be used in the following ways: • •

Manage the prder of operations in the machine. Reduce cycle time by optimizing tool change. You can synchronize the tool in such a way that without going back to the home position, the tool can finish machining operation on one part and immediatelty start the other operation on the second part.

The example below is of a milling part, on which Channel Synchronization is defined.

331
