Siemens Sinumerik SLOT 2 cnc program ( Circumferential slot )


                                                       Sinumerik SLOT 2 is a consolidated roughing-finishing cycle. This cycle used for machine circular slot arranged on a circle.



SLOT 2 ( RTP ,RFP , SIDS , DP , DPR , NUM , AFSL , WID , CPA , CPO , RAD , STA1 , INDA                 , FFD , FFP1 , MID , CDIR , RAL , VARI , MIDF , FFP2 , SSF , FFCP )


Where RTP = Retraction plane 
            RFP = Reference plane 
            SIDS = Safety clearance
            DP =  Slot depth 
            DPR = Slot depth  relative to reference plane 
            NUM = Numbers of slots
            LENG = Length of slot
            WID = Width of circumferential slots
            CPA = Center point of circle , abscissa (x-axis)
            CPO = Center point of circle , ordinate (y-axis)
            RAD= Radius of a circle 
            STA1= Starting angle
            INDA= Increamenting angle
            FFD = Feed rate for depth infeed
            FFP1 = Feed rate for surface machining
            MID = Maximum infeed depth for one infeed
            CDIR = Machining direction  value :
                             2( for G02 )
                             3(for G03 )
            FAL = Slot edge finishing allowance 
            VARI =  Machining type 
                                      UNIT DIGIT : 
                                      0- complete machining
                                      1- Roughing
                                      2- Finishing
                                      TENS DIGIT
                                      0- Positioning from a slot to slot on the straight line with G0
                                      1- Positioning from a slot to slot on a circular path with a feed rate
            MIDF = Maximum infeed depth for finishing 
            FFP2 = Feedrate for finishing 
            SSF = Speed when finishing
            FFCP = Feed rate for intermediate positioning on a circular path in mm/min


Example :- Depth of slots is 30 mm & radius of a circle (RAD) is 30 mm

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 X60 , Y50 & Z50 .
N40 - call SLOT 2 ( RTP= 10 , RFP= 0 , SIDS= 5 , DP=-30 , DPR =_ , NUM = 3 , AFSL= 60 , WID=15 ,CPA = 60 , CPO= 50 , RAD= 30 , STA1=60 , INDA= 120 ,FFD = 100 , FFP1= 300 , MID= 10 , CDIR = 2 , FAL =0.5 , VARI= 2 , MIDF= 10 , FFP2 =400 , SSF= 1200 , FFCP =10 )
N50 - Tool goes rapidly up position .
