DISCRIPTION 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 on clockwise at speed 1000 rpm.

N05 – Coolant ON .

N06 – Rapid command  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 ( CYCLE 95 ) 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 -  INT=11 (Operation perform internally therefore we take  11, if externally we take 9)

             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:- In sub program there only used G01 ,G02 OR G03

RAM .SPF – Sub program name

N01 -  Tool take position linearly at X axis at X 30 and Z at 0 .(tool ready )

N02 -  There is radius cutting means circular interpolation counter clockwise ( means tool cutting path is anti clockwise) , where X40 ,  Z-20 AND radius 10 mm .

N03 – Tool cuts linearly X 30 and Y -40 .

N04 – There is chamfer 5 X 45⁰ ,                  

               Tan  angle  45 = 1  

              Tan  Ɵ = Opp / Adj

              Opposite side = 5

          Tool  moves  linearly at X 35 and  z-45

N05 -  Tool  moves  linearly at X 35 and  z-60 .

,

N06 - There is again  chamfer 5 X 45⁰ ,                 

               Tan  Ɵ = Opp / Adj

               Tan  angle  45 = 1

               Opposite side = 5

          Tool  moves  linearly at X 30 and  Z-65 .

N07 - Tool  moves  linearly at X 30 and  z-75

N08 – Similarly to block no N04 ,  30 – (5+5) = 20

           Last diameter is 20

          Tool  moves  linearly at X 20 and  Z-80 .
