- Command canceling the offset vector temporarily
During offset mode, if G50 (workpiece coordinate system setting) or
G52 (local coordinate system setting) is commanded, the offset vector
is temporarily cancelled and thereafter offset mode is automatically
restored.
In this case, without movement of offset cancel, the tool moves
directly from the intersecting point to the commanded point where
offset vector is canceled.
Also when restored to offset mode, the tool moves directly to the
intersecting point.

Before specifying G28 (reference position return), G29 (return from
reference position), G30 (second, third, and fourth reference position
returns), G30.1 (floating reference position return), and G53 (machine
coordinate system selection) commands, cancel offset mode, using
G40. If an attempt is made to specify any of the commands in offset
mode, the offset vector temporarily disappears.
- Canned cycles (G90, G92, G94) and multiple repetitive cycles (G71 to G76)
See the cautions for the tool nose radius compensation related canned
cycles.
