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.

N10- Tool change command , select tool no. 4
N20- Absolute co-ordinate command , cancel canned cycle command , selection of  XY plane, rapid command, work coordinate for tool positioning at  X0 and Y0.
N30- Tool height offset compensation command , where tool is 100 along Z axis , tool hight code H4.
N40- Spindle on clockwise , speed is 1500 rpm .
N50- Coolant ON .
N60- Return to R-plane in canned cycle , counter drilling command ,first drilling position is X20 and Y20 Depth of drilling is 10 , R- plane distance is 5 ,dwell time is 1 sec ,   feed rate is 120. 
N70- Second drill position where X 50 and Y20 and drilling depth is 10.
N80-Tool return initial position , cancel canned cycle , rapid command , where tool along Z axis is 100 .
N90-Spindle off , coolant off, Main program end .
