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 .

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 X0 and Z0 .(Position A)

N02 – Tool start cutting  linearly at X14 and Z-14 ( Position A to B)

N03 – Tool moves toward position C linearly at X14 and Z-24 .(Position B to C)

N04 – There isouter radius=3 mm , it means tool moves clockwise toward  D at X20 and Z-27 .(Position C to D)

N05 - Tool moves toward position E linearly at X20 and Z-37 .(Position D to E)

N06 - Tool moves toward position F linearly at X22 and Z-37 .(Position E to F)

N07- Tool moves toward position G linearly at X22 and Z-52.(Position F to G)

N08- Tool moves toward position H linearly at X25 and Z-52 .(Position Gto H)
N09- Sub program end .

(Note : there is no need to machining  to last diameter , because given diameter for billet is 25 )
