DESCRIPTION OF PROGRAM 
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 ,first boring position is X20 and Y20 Depth of boring is 45 , R- plane distance is 5 , shift amountof tool at bottom of hole is 5, dwell time is 1 sec ,   feed rate per minute is 2.5 . [A]

N70- Second boring position where , X20 , Y50 and depth of operation is Z-45 .[B]

N80- Third boring position where , X60 , Y50 and depth of operation is Z-45 .[C]

N90- Fourth boring position where , X100 , Y50 and depth of operation is Z-45 [D]

N100- Fifth boring position where , X100 , Y80 and depth of operation is Z-45 .[E]

N110- Tool return initial position , cancel canned cycle , rapid command , where tool along Z axis is 100 .
N120- Spindle off , coolant off, Main program end .
