Groove (CYCLE930)
Function
You can use the "Groove" cycle to machine symmetrical and asymmetrical grooves on any
straight contour elements.
You have the option of machining outer or inner grooves, longitudinally or transversely (face).
Use the "Groove width" and "Groove depth" parameters to determine the shape of the groove.
If a groove is wider than the active tool, it is machined in several cuts. The tool is moved by a
maximum of 80% of the tool width for each groove.
You can specify a finishing allowance for the groove base and the flanks; roughing is then
performed down to this point.
The dwell time between recessing and retraction is stored in a setting data element.
Machine manufacturer
Please also refer to the machine manufacturer's specifications.
Approach/retraction during roughing
Infeed depth D > 0
1. The tool first moves to the starting point calculated internally in the cycle at rapid traverse.
2. The tool cuts a groove in the center of infeed depth D.
3. The tool moves back by D + safety clearance with rapid traverse.
4. The tool cuts a groove next to the first groove with infeed depth 2 · D.
5. The tool moves back by D + safety clearance with rapid traverse.
