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 .

N02 -  Referance point command where tool at X0 Z0 .

N03 – Tool change command , select tool no 6 and offset diameter 01 .

N04 – Spindle 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)

N11-  Sub program end .
