The only difference between this cycle and the Standard Drilling G81 is that the tool return to RAL quote is done at working feed, between ENT and RAP, and at rapid (G00) from RAP to RAL.
The cycle Data Entry is activated, in MDI and Edit modes, through this keys sequence:
G85 <ENT=..> <RAP=..> <RAL=..>
| Parameter | Description |
|---|---|
| ENT | Depth quote reached at working feed |
| RAP | Quote reached in rapid at the beginning of cycle |
| RAL | Return Quote reached at rapid |
