CIRCLE INTERPOLATION MILLING CALCULATOR

NOTE: During internal circle interpolations, the outside diameter of a milling cutter advances faster than the centerlin tool. This will produce a thicker chip than the calculated feed rate. (IPT) During external circle interpolations, the outs diameter of a milling cutter will advance slower than the centerline of the tool. This will produce a thinner chip than th calculated feed rate. (IPT) When less than 1/2 of the diameter of the tool is engaged (radial) with the workpiece, there be radial chip thinning effects. This calculator solves for both effects. Enter the cutter diameter, radial width of cut (W internal or external circle diameter (diameter being produced, not starting diameter) and the desired chip load per too The calculator will give you the "adjusted" feed rate (IPT) to maintain the desired chip thickness.

NOTE: If the operation is not a full circle interpolation, simply input into the "Circle Diameter" data cell what the theoretical circle size would be

EXAMPLE: A 1.00 inch diameter end mill cuts an internal 90 degree corner that has a .625 inch radius. The circle diameter is the radius X 2, or 1.2 For ID operations the radius of the cutting tool must always be equal to or smaller than the radius to be interpolated.

The circle diameter is the radius X 2, or 8.00 inches. practical , it is a good idea to have the tool diameter greater than about 1/2 of the radial width of cut on external interpolations.

NOTE: For use when less than 1/2 of the diameter of milling cutter is engaged in the width of cut (WOC) and for all slo type cutters. The chip thickness produced with less than 1/2 of the diameter in radial will be thinner than calc feed per tooth due to radial chip thinning. Enter the "desired chip load" (IPT) into the calculator.
