18.5.5 Deselecting the TRC (G40)
G40 instruction
TRC is deselected with the G40 instruction.
Special points to be noted
• TRC can only be deselected in a program block with G0 (rapid traverse) or G1 (linear interpolation).
•If D0 is programmed when tool radius compensation is active, compensation is not deselected and error
message 10750 is output.
• If a geometry axis is programmed in the block with the tool radius compensation deselection, then the
compensation is deselected even if it is not on the current plane.
18.5.6 Compensation at outside corners
G450/G451
The G functions G450/G451 can be used to control the response with discontinuous block transitions at outside
corners:
