This section describes the tool length offset cancellation and restoration
performed when G53, G28, G30, or G31 is specified in tool length offset
mode. Also described is the timing of tool length offset.
(1)Tool length offset vector cancellation and restoration, performed when
G53, G28, G30, or G30.1 is specified in tool length offset mode
(2)Specification of the G43/G44 command for tool length offset A/B/C,
and independent specification of the H command
When G53, G28, G30, or G30.1 is specified in tool length offset mode,
tool length offset vectors are canceled as described below. However, the
previously specified modal G code remains displayed; modal code
display is not switched to G49.
(1) When G53 is specified
Command Specified axis Common to type A/B/C
G53P_;
Tool length offset
axis
Canceled upon movement being
performed according to a speci-
fied value
Other than tool
length offset axis
Not canceled
NOTE
When tool length offset is applied to multiple axes, all
specified axes are subject to cancellation.
When tool length offset cancellation is specified at the same time, tool
length offset vector cancellation is performed as indicated below.
