Siemens Sinumerik SLOT 1 cnc program (Slots on a circle )

                               
                                                  The cycle SLOT1 is a consolidated roughing-finishing cycle. Use this cycle to machine slots arranged on a circle. The longitudinal axis of the slots aligned radially. In contrast to the long hole, a value is defined for the slot width.


SLOT 1 (  RTP , RFP , SDIS , DP , DPR , NUM , LENG , WID , CAP , CPO ,RAD , STA1 , INDA , FFD , FFP1 , MID , CDIR , FAL , VARI , MIDF , FFP2 , SSF , FALD , STA2 )

Where RTP = Retraction plane 
            RFP = Reference plane 
            SIDS = Safety clearance
            DP =  Slots depth 
            DPR = Slots depth  relative to reference plane 
            NUM = Numbers of slot
            LENG = Length of slots
            WID = Width of slots
            CPA = Center point of circle , abscissa (x-axis)
            CPO = Center point of circle , ordinate (y-axis)
            RAD= Radius of circle 
            STA1= Starting angle
            INDA= Increamenting angle
            FFD = Feed rate for depth infeed
            FFP1 = Feed rate for surface machining
            MID = Maximum infeed depth for an infeed
            CDIR = Machining direction  value :
                             0- Down cut milling ( correspond to direction of spindle rotation )
                             1 - Down-cut milling
                             2 - with G02 ( Independent of direction of rotation of spindle )
                             3 - with G03
            FAL = Slot edge finishing allowance 
            VARI =  Machining type 
                                      UNIT DIGIT : 
                                      0- complete machining
                                      1- Roughing
                                      2- Finishing
                                      TENS DIGIT
                                      0- Perpendicular to G0
                                      1- Perpendicular to G1
                                      2- Oscillation with G1
            MIDF = Maximum infeed depth  for finishing
            FFP2 = Feedrate for finishing 
            SSF = Speed when finishing
            RALD = Slot base finishing allowance
            STA2 = Maximum insertion angle for oscillation movement
