- Specifying offset on two or more axes
Tool length compensation B enables offset on two or more axes by
specifying offset axes in multiple blocks.
To perform offset on X and Y axes
G19 G43 H_; Performs offset on the X axis.
G18 G43 H_; Performs offset on the Y axis.
Tool length compensation C suppresses the generation of an alarm
even if offset is performed on two or more axes at the same time, by
setting TAL (No. 5001#3) to 1.
- Tool length compensation cancel
To cancel offset, specify either G49 or H0. Canceling offset causes
the shifting of the coordinate system to be undone. If no move
command is specified at this time, the tool will not move along the
axis.
Caution
CAUTION
1 Specifying tool length compensation (a shift type)
first and then executing an incremental command
causes the tool length compensation value to be
reflected in the coordinates only, not in the travel
distance of the machine; executing an absolute
command causes the tool length compensation
value to be reflected in both the movement of the
machine and the coordinates.
2 If a programmable mirror image is effective, the tool
length offset is applied in the specified direction.
3 No scaling magnification is applied to the tool length
offset value.
4 No coordinate system rotation is applied to the tool
length offset value. Tool length offset is effective
in the direction in which the offset is applied.
5 The tool length offset operation is independent of
the cutter compensation offset operation.
6 Three-dimensional coordinate conversion is applied
to tool length offset. If tool length offset is made
effective to multiple axes, the tool length offset must
be canceled for one axis at a time.
7 With the WINDOW command, changing parameter
TOS during automatic operation does not cause the
tool length offset type to be changed.
