If the origin, presetting, or workpiece offset 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 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
threading.
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.
WARNING
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 tool.
