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.
Starting point
The starting point for the approach/retraction cycle is the safety clearance approached after the
last machining operation.
Tool change
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.
CAUTION
Risk of collision
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.
