DESCRIPTION OF PROGRAM :- 
MAIN PROGRAM
HARSH .MPF – Main program name
N01-   Program in absolute co-ordinate system ,  all dimension in mm , feed in mm permin , feed rate 100 .
N02Referance point command where tool at X0 Z0 .
N03 Tool changecommand , select tool no 6 and offset diameter 01 .
N04Spindle onclockwise at speed 1000 rpm.
N05 Coolant ON.
N06 – Rapid command to near to the job and ready for machining .
N07 – For understanding these  block we have to need knowledge about “stock removal  cycle data “
Refer this link – STOCK REMOVAL CYCLE DATA
The following data directly put value in computer
          NPP – RAJ
          MID – 0.2
          FALZ – 0.1
          FALX – 0.1
          FAL -    0.1
          FF1 -   200
          FF2 –  300
          FF3 -   200
          VARI -  EXT=9(Operation perform externally therefore we take  9, if internally we take 11)
          DT -   ___ (skip it)
          DAM -  ____(skip it)
          VRT -   ____(skip it)
N08 -  Referance point command where tool at X0 Z0 .
N09 Coolant  OFF .
N10 – Main program end .
 SUB PROGRAM
( NOTE -In sub program there is no use of G00 rapid command )
RAM .SPF – Sub program name
N01 – Tool moves linearly at X11 and Z0 .(Position A)
N02 – Tool start cutting  linearly at X14 and Z-1.5(chamfer) ; ( Position A to B)
               For chamfer calculation refer this link -
N03 – Tool moves toward position C linearly at X14 and Z-10 .(Position B to C)
N04 – There is inner radius=3 mm , it means tool moves counter clockwise toward  D at X20 and Z-13 .(Position C to D)
N05 - Tool moves toward position E linearly at X20 and Z-20 .(Position D to E)
N06 - – There is outer  radius=3 mm , it means tool moves clockwise toward  F at X26 and Z-23 .(Position E to F)
N07- Sub prog.  end
(Note : there is no need to machining  to last diameter , because given diameter for billet is 26 mm )
