21. AXIS CONTROL FUNCTIONS
To replace the tool damaged during machining or to check the status of
machining, the tool can be withdrawn from a workpiece. The tool can
then be advanced again to restart machining efficiently.
The tool withdrawal and return operation consists of the following four
The tool is retracted to a predefined position using the TOOL WITHDRAW
The tool is moved to the tool–change position manually.
The tool returns to the retract position.
The tool returns to the interrupted position.
For the tool withdrawal and return operations, see III–4.8.
: Position where the TOOL WITHDRAW switch was turned on
: Programmed position
: Position to which the tool is retracted by manual operation
: Retraction path
: Manual operation (withdraw path)
: Return path
Specify a retraction axis and distance in the following format:
G10.6 IP_ ;
_ : In incremental mode, retraction distance from the position
where the retract signal is turned on
In the absolute mode, retraction distance to an absolute position
The specified amount of retraction is effective until G10.6 is next
executed. To cancel the retraction, specify the following:
Specify the amount of retraction, using G10.6.
G10.6 ; (as a single block containing no other commands)
AND RETURN (G10.6)
