Danger of collision!
When the coupling is activated, the control positions the tool in
the Z axis to the value of the parameter Z. Danger of collision
during approach!
Pre-position the tool if required before activating the coupling
(before the cycle)
Programming notes:
Program a workpiece blank increased by the center
offset in the radius if you are using turning cycles
that are referenced to the workpiece-blank definition
Program the starting point increased by the center
offset in the radius if you are using turning cycles
that are not referenced to the workpiece-blank
definition
Reduce the spindle speed if you increase the center
offset
Reduce the maximum rapid traverse F if you increase
the center offset
Use identical values for the parameter Q when
activating and deactivating the coupling
Programming sequence:
Position the cursor in the MACHINING program section
Program function G726 with H1 (activate coupling)
Program turning cycles
Program function G726 with H0 (deactivate coupling)
Canceling the program run automatically deactivates the
coupling.
