9 Tool Offsets 05.91
9.5 G40/G41/G42 Intersection cutter radius path compensation (CRC)
Remedy:
Program the functions G58/G59/G33 before selecting the cutter radius compensation, or
cancel the cutter radius compensation (select G58/G33) and then reselect CRC.
When CRC has been selected, including the G40 block, the effective zero offset must not be
changed.
