Command

G41

Cancellation

G40

The function G41 switches on the miller/cutter radius compensation. The tool is located to the left of the workpiece in the direction of movement.

As has already been seen for the length compensation, the cutter radius compensation can only be activated when G0 or G1 is in effect. The axes of the plane must be driven when the cutter radius compensation is selected.

Cutter radius compensation does not apply to full circles

The cutter radius compensation does not support full circles. Full circles have to be split into semicircles, for example.
