21. AXIS CONTROL FUNCTIONS
If the origin, presetting, or workpiece origin offset value (or External
workpiece origin offset value) is changed after retraction is specified with
G10.6 in absolute mode, the change is not reflected in the retraction
position. After such changes are made, the retraction position must be
respecified with G10.6.
When the tool is damaged, automatic operation can be interrupted with
a tool withdrawal and return operation in order to replace the tool. Note
that if the tool offset value is changed after tool replacement, the change
is ignored when automatic operation is resumed from the start point or
other point in the interrupted block.
When withdrawing the tool manually in the tool withdrawal mode, never
use the machine lock, mirror–image, or scaling function.
Tool withdrawal and return operation cannot be performed during thread
Tool withdrawal and return operation cannot be performed during a
drilling canned cycle.
Upon reset, the retraction data specified in G10.6 is cleared. Retraction
data needs to be specified again.
The tool withdrawal and return function is enabled even when the
retraction command is not specified. In this case, retraction and
repositioning are not performed.
The retraction axis and retraction distance specified in
G10.6 need to be changed in an appropriate block
according to the figure being machined. Be very careful
when specifying the retraction distance; an incorrect
retraction distance may damage the workpiece, machine, or
