3.5 BORING (Cycle 202, DIN/ISO:
G202)
Cycle run
1 The TNC positions the tool in the spindle axis at rapid traverse FMAX
to the setup clearance above the workpiece surface.
2 The tool drills to the programmed depth at the feed rate for
plunging.
3 If programmed, the tool remains at the hole bottom for the entered
dwell time with active spindle rotation for cutting free.
4 The TNC then orients the spindle to the position that is defined in
parameter Q336.
5 If retraction is selected, the tool retracts in the programmed
direction by 0.2 mm (fixed value).
6 The TNC moves the tool at the retraction feed rate to the setup
clearance and then, if entered, to the 2nd setup clearance at FMAX.
If Q214=0, the tool point remains on the wall of the hole.
