On above fig. we have to bore 30 mm bore for this we used 30 mm boring bar .

N10- Tool change command , select tool no. 5
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 , fine boring command ,incremental command ,first boring position is X30 and Y20 Depth of boring is 45 , R- plane distance is 5 , shift amount of tool at bottom of hole is 5, dwell time is 1 sec ,no of  times operation repeated , feed rate per minute is 2.5 .[ note:- here is provide incremental command , it  means next operation perform from incremental distance from first operation position )
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 .
