Fanuc G82 counter boring cycle II Drilling cycle II

                                     G82 cycle is used for normal drilling . Cutting feed is performed to the bottom of the hole .At the bottom , a dwell is performed , the tool is retracted. This cycle is used to drill hole more accurately with respect to depth.

G82 X_ Y_ Z_ R_  P_ F_ K_;
                    Where , XY- Position of hole
                                  Z-  Depth of operation performe
                                  R-  R plane position
                                  P- Dwell time when tool reach at bottom
                                  F- cutting feed rate 
                                  K- no of times operation repeats.
Operation :- First tool positioning at XY axis , after the tool rapidly traverse up to R-plane level , after that tool is start drilling operation . When the bottom of the tool has been reached, a dwell is performed. Then tool is retracted rapidly.
