        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 X0 and Z0 .(Position A)

N02 – External radius 15 mm where X30 and Z-15 ( Circular interpolation clockwise) (Position A to B )

N03 – Tool moves linearly  towards C , where X30 and Z-30 . (Position B to C)

N04 – Tool moves linearly  towards C , where X40 and Z-35 . (Position C to D)

N05- Internal radius 5 mm where X50 and Z-40 ( Circular interpolation counter  clockwise) (Position D to E )

N06- Tool moves linearly  towards F , where X70 and Z-55 . (taper)(Position E to F)

N07- Tool moves linearly  towards G , where X70 and Z-75 . (Position F to G)

N08- Tool moves linearly  towards H , where X80 and Z-75 . (Position G to H)

N09 – Sub program end .
