The workpiece position can be changed by setting the coordinate system
as shown below.
Workpiece
X axis
Z axis
G41 (the workpiece is
on the left side)
G42 (the workpiece is
on the right side)
Note
NOTE
If the tool nose radius compensation value is negative, the
workpiece position is changed.
G40, G41, and, G42 are modal.
Don’t specify G41 while in the G41 mode. If you do, compensation will
not work properly.
Don’t specify G42 while in the G42 mode for the same reason.
G41 or G42 mode blocks in which G41 or G42 are not specified are
expressed by (G41) or (G42) respectively.
When the tool is moving, the tool nose maintains contact with the
workpiece.
