Working with a B axis (only 840D sl)
16.5 Approach/retraction
Turning
828 Operating Manual, 01/2015, 6FC5398-8CP40-5BA2
If you want to optimize approach/return for swiveling with the B axis, you can create a
special cycle that ignores the automatic approach/retraction strategy.
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 three positions
(P1 to P3) to the tool change point and through a maximum of three additional positions (P4
to P6) to the next starting point.
The 1st, 3rd, 4th and 6th positions move the linear axes, while the 2nd and 5th positions
move the rotary axes.
If no tool change is needed you can generate no more than six motion blocks.
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.
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.
