Programming the approach/retraction cycle
If you wish to shorten the approach/retraction for a machining cycle or solve a complex
geometrical situation when approaching/retracting, you can generate a special cycle. In this
case, the approach/retraction strategy normally used is not taken into account.
You can insert the approach/retraction cycle between any machining step program blocks,
but not within linked program blocks.
The starting point for the approach/retraction cycle is the safety clearance approached after
the last machining operation.
If you want to perform a tool change, you can move the tool through a total of 3 positions (P1
to P3) to the tool change point and through a maximum of 3 additional positions (P4 to P6) to
the next starting point. If the tool does not need to be changed, however, you have a total of
6 positions available for the approach to the next starting position.
If 3 or 6 positions are not sufficient for the approach/retraction, you can call the cycle several
times in succession to program further positions.
Note that the tool will move from the last position programmed in the approach/retraction
cycle directly to the starting point for the next machining operation.
