Siemens Sinumerik POCKET 1 cnc milling program ( Rectangular pocket )


                      Sinumerik POCKET 1 cycle is used to machine rectangular pocket with a starting angle(STA1) or without starting angle (any position). The cycle is a consolidated roughing-finishing cycle.

Without angle 

With angle (STA1)


POCKET 1 ( RTP , RFP , SIDS , DP, DPR , LENG , WID ,cRAD , CPA, CPO , STA1 , FFD ,                             FFP1 , MID , CDIR , FAL , VARI , MIDF , FFP2 , SSF )


Where , RTP = Retraction plane 
              RFP = Reference plane 
              SIDS = Safety clearance
              DP = Depth of pocket 
              DPR = Depth of pocket relative to reference plane 
              LENG = Length of pocket 
              WID = Width of pocket
              CRAD = Pocket corner radius 
              CPA = Pocket center point abscissa
              CPO = Pocket center point ordinate
              STA1 = Angle between Abscissa & longitudinal axis .
              FFD = Feed rate for depth infeed 
              FFP1 = Feed rate for surface machining 
              MID = Maximum infeed depth for one infeed 
              CDIR = Direction of machining 
                           Value : 2 (G02)
                                       3 (G03)
              FAL = Finishing allowance at the edge of pocket 
              VARI = Machining type 
                           Value : 0- complete machining 
                                       1- Roughing 
                                       2- Finishing
             MIDF = Maximum infeed depth for finishing 
             FFP2 = Feed rate for finishing 
             SSF = Speed when finishing

DESCRIPTION

HARSH.MPF- Name of the main program
N10 -  Absolute coordinate system, a metric input command, Tool change command select tool no  3 .
N20- Spindle On clockwise at the speed 1000 rpm & coolant is on 
N30-  Internal threading at XY- plane, rapid traverse command where tool takes a position at                     reference point where X50 , Y50 & Z50 .
N40- Call POCKET 1 ( RTP= 10 , RFP= 0 , SIDS = 5 , DP= _ , DPR = -10 , LENG = 50 , WID = 30 ,        CRAD = 8 , CPA= 50 , CPO =50 , STA1= 30 , FFD = 100 , FFP1= 300 , MID =10 , CDIR = 2          , FAL =0.5 , VARI = 2 , MIDF = 10 , FFP2 = 400 , SSF= 1200 )
N50 - Tool goes rapidly up position .
