Taper turning with g90 cycle II fixed/ box/axial/id-od cutting cycle II

                                              Friends this cycle has many names like ; turning cycle , fixed cycle , ID/OD cutting cycle , Box cycle. G90 IS mostly used but sometime machine model can not adopt G90 , that time we can insert G77 or G20 which is accept by machine model . G90/G77/G20  these g code meaning is same .

DESCRIPTION OF MAIN PROGRAM :-

O1453 - Name of main program
N10 - Referance point command X0 and Z0
N20- Tool change command , select tool no 2
N30- Maximum spindle speed command , speed is 1500 rpm
N40- Spindle ON clockwise , constant spindle speed , speed is 200 rpm
N50- Coolant ON
N60- Rapid action command , where X80 and Z2
N70- Turning /ID/OD/Fixed/axial cutting cycle command , starting position in X- axis is 60 , cutting upto 40 in z- axis(for first step ) , feed rate is 0.25
           First cut start from x- axis is 55

                                     second cut 50

                                         third cut 45

                                       fourth cut 40 ( first step is complete)

          1. Taper turning is start cutting upto 30 mm in  z axis and taper value is 2 mm for one side (it means in one cut reduce 4 mm dia)[in these case dia is 40 mm due to taper value it reduce 4mm ; dia is 36 mm]

2. Taper value is 3 , it means dia is reduce 6 mm , final dia is 30 mm .

N80- Referance point command X0 and Z0

N90- Spindle OFF , coolant OFF , main prog. end
