Fanuc G84 tapping cycle program

                         Fanuc G84 cycle performs tapping. In this tapping cycle, when the bottom of the hole has been reached, the spindle is rotated in the reverse direction.
G84 X_ Y_ Z_ R_ P_ F_ K_
                    Where , XY- Position of hole
                                  Z-  Depth of operation performe from retraction plane
                                  R-  R plane position.(retraction plane)
                                  P-  Dwell time
                                  F- cutting feed rate 
                                  K- no of times operation repeats.

Operation:Tapping is performed by rotating the spindle clockwise. When the bottom of the hole has been reached, the spindle is rotated in the reverse direction for retraction. This operation creates threads.
