Reaming (CYCLE85)

Function
With the "Reaming" cycle, the tool is inserted in the workpiece with the programmed spindle
speed and the feedrate programmed at F.
If Z1 has been reached and the dwell time expired, the reamer is retracted at the
programmed retraction feedrate to the retraction plane.
Approach/retraction
1. The tool moves with G0 to safety clearance of the reference point.
2. The tool is inserted into the workpiece with the programmed feedrate F until it reaches
3. Dwell time DT at final drilling depth.
4. Retraction to retraction plane with programmed retraction feedrate FR.
