Tool Diameter Compensation
Tool diameter compensation allows the
machined edges shown directly on the
workpiece to be programmed instead of
the center of the tool. The ProtoTRAK
KMX then automatically compensates for
the programmed geometry so that the
desired results are obtained.
If the cutter in the sketch above is moving from left to right from point X1, Y1 to X2, Y2 and
on to X3, Y3, these actual points can be programmed instead of the center of the cutter.
Or, the actual desired circle with radius R can be programmed
instead of the radius of the center of the cutter Rc.
Tool cutter compensation is always specified as the tool either right or left of the workpiece
while looking in the direction of the tool motion.
Examples of tool right are: Examples of tool left are:
Tool center means no compensation either right or left. That is, the centerline of the
tool will be moved to the programmed points.

Tool Diameter Compensation when Contouring in Z with
Part Geometry
Left and right tool diameter offsets are always those projected into the XY plane. Tool
offsets in the Z direction are always up and assume the use of a ball end mill. When
contouring in the Z-axis, this up tool offset is always activated regardless of left, right,
center if the Part Geometry option is selected. There is no Z-axis up tool offset applied
when the Tool Path option is selected.
