unction
This command assumes the correction of cylindrical tool radius orthogonal to a plane. The correction
offset adapts automatically to two axes vertical to the plane, and the corrected path shifts from the com-
manded path by the tool radius.
This command acts on G01, G02, and G03. The user can select XY, YZ, or ZX plane with Plane Selec-
tion (G17/G18/G19).
G40 is Cutter Compensation Cancel, G41 is Cutter Compensation Left, and G42 is Cutter Compensa-
tion Right.
The compensation cannot be started with Circular Interpolation (G02/G03).
The travel distance at startup must be greater than the cutter radius. However, when the tool moves
inside the arc, the cutter radius must be smaller than the circular command.
The extent of correction depends on the selected tool.
