DESCRIPTION OF PROGRAM :- 

MAIN PROGRAM
HARSH .MPF – Main program name
N01-   Program in absolute co-ordinate system ,  all dimension in mm , feed in mm per min , feed rate 100 .
N02Referance point command where tool at X0 Z0 .
N03 Tool change command , 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 X20 and Z0 .(Position A)
N02 - Tool start cutting  linearly at X24 and Z-2 (chamfer) ; ( Position A to B)
N03 – Tool moves linearly toward position C at X24 and Z-10 .( Position B to C)
N04 – There is inner radius=2 mm , it means tool moves counter clockwise toward  D at X24 and Z-14 .(Position C to D)
N05 - Tool moves linearly toward position E at X50 and Z-32. (Position D to E)
N06 - There is inner radius=2 mm , it means tool moves counter clockwise toward  D at X60 and Z-37 .(Position E to F)
N07 - Tool moves linearly toward position G at X60 and Z-45. (Position F to G)
N08 - Tool moves linearly toward position H at X56 and Z-47.(Chamfer) (Position G to H)
N09-  Tool moves linearly toward position I at X56 and Z-52. (Position H to I)
N10-- Tool moves linearly toward position J at X60 and Z-54 .(Chamfer) (Position I to J)
