Previous Cutter Offset

Adjust the diameter of the previous cutter. For instance, if you insert a value of 0.020, the system will increase the diameter of the previous tool definition by 0.020 per side, before using it to calculate the areas that will be cut with the current tool. A larger tool will create larger areas to be cut, thus giving you an overlap between the previous procedure and your Cleanup procedure.

This enables over or under-machining between the current cutter and the previous cutter without the need to define an oversized dummy previous cutter.

This parameter is very useful in cases where the Previous Cutter radius is very close to the surface radius of curvature. In these cases, the detected unmachined areas might be scattered and irregular. Using a Negative Previous Cutter Offset will eliminate all these suspected areas, and a Positive Cutter Offset will make sure that all of them are detected and machined by the current cutter.
