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.

DESCRIPTION OF PROGRAM
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 .
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 boring command ,Incremental co-ordinate 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 , operation reopeated 3 times. [Note:- how to know repeated operation? :- here we see the drilling perform on three place same diameter and same distance in X, Y and Z axis .so , we do only little more change in N60 is add G91 and K3 and N70 only add G90 command to cancel G91 command .]
N70-Absolute coordinate command ,tool return initial position , cancel canned cycle , rapid command , where tool along Z axis is 100 .
N80-Spindle off , coolant off, Main program end
Fanuc G82 counter boring / drilling cycle with number of operation repeated
