DISCRIPTION 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 .
N03Tool change command , select tool no 2 and offset diameter 01 .
N04Spindle onclockwise at speed 600 rpm.
N05 – Coolant ON .
N06Rapidcommand to near to the job and ready for machining .
N07 – For better understanding refer this link – THREADING CYCLE 97
          This  parameter value directly put into computer .Fig shows 20M X2 , it means given is 20mm                 diameter and pitch 2 .

      PIT -    PIT means pitch of threads is 2 mm .
      MPIT -  It is also pitch of thread but it takes whenever if not given ,it is standards threads pitch                        from 3.5  to 60 . To produce metric cylindrical threads . But in these program we don’t                        need MPIT , we take zero                                                                                  
      SPL –  Starting point of thread along  Z – axis , we take zero .
      FPL -  End point of thread along Z – axis , we take 30 .(Length)
      DM1 – Diameter of thread at starting point is 10 .
      DM2 – Diameter of thread at end point is also 10 .
      APP – How much tool away from when start operation , in these program no clearance is provide
                 hence we take zero .                 
      ROP -  After threading  ideal run path for Z axis , we take zero .
      TDEP – Thread depth , there is calculation  0.6134 x pitch ,
                        0.6134 X 2 = 1.226
      FAL – Finishing allowance for finish cut , we take 0.05 .
      IANG – Thread angle , if angle is 60 we take always half of the angle 30.
      NSP – Used for offset at starting  10  , 2, but we naver take offset in these program hence we                       used 0 .    
      NRC – No. of rough cut , its deped on depth of cut . We take 12 .
      NID – Finishing cut at last . we take 2 .
      VARY – In computer panel there is four option for thread , generally we select for internal                                 threading  No. 4.      
                
     NUMTH – No of thread cut this is depend upon single start and multi-start . We take 1 .
     VRT   ___ (skip it )
                                         
N08Referance point command where tool at X0 Z0 .
N09 – Coolant  OFF .
N10 – Main program end .
