8. Method of cancellation of compensation
G40 is the command for canceling tool radius
compensation C and for positioning or feed-
ing the tool to just programmed end point.
In this case, the tool moves to a point
the
normal line at the end point of the block im-
mediately before the block containing G40.

N o t e : The movement identical to what is
above is also obtained when block
split into two blocks as follows. shown
N21 is
Therefore, no portion will be left unmachined
even when a cancellation with sharp angle is
programmed.
Because G40 accompanies
movement, program it in the GOO or
GO1 mode like G41, G42. An input error “027”
occurs if group A other than GOO, G02 is used.
