15.5 Approach/retraction
The numbers (1 - 6) represent the processing sequence.
Note
Programming additional positions
If three or six positions are not sufficient for the approach/retraction, you can call the cycle
several times in succession to program further positions.
NOTICE
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.
