Ending Cutter Compensation
Cutter compensation is ended with G40. A positioning (G00) specification is followed by G40. Cutter compensation cannot be ended
by circular interpolation (G02 or G03).
As shown in the figure below (on the left-hand side), the tool is shifted to the left or the right by the amount of offset as it returns to the
end point. Operation takes place when a command for moving to a block is specified when cutter compensation finishes.
In the same way as when starting cutter compensation, outer-side travel includes Type A and Type B paths.
