EMCO WINNC SINUMERIK 810/820 TPROGRAMMINGL97Thread Cutting CycleLongitudinal, face, inside and outside threads can beprogrammed.The infeed of the tool occurs automatically and isdegressively quadratic. This keeps the cross sectionof the chip constant.Programming the parameter:R27XR31R32R22R25R20Thread cutting cycleR24R21R26R29ZR20R21R22R23R24R25R26R27R28R29R31R32Thread pitch (always the value parallel to axis)Start point of the thread in XStart point of the thread in ZR21 and R22 describe the real start point at thecontour.Number of idle cutsThread depth (positive value = inside thread,negative value = outside thread)Finishing offsetAfter automatic cut dividing with roughing occursa finishing cut with the programmed cuttingdepth.Thread let-in, incremental without signThread let-out, incremental without signThe values R26 and R27 always will be enteredparallel to axis without sign. With taperthreads the correct starting and end points willbe calculated automatically.Number of roughing cutsInfeed angle (half flank angle)Flank infeed is only possible with longitudinalor face threads (no taper threads)End point of the thread in X (absolute)End point of the thread in Z (absolute)R31 and R32 describe the real end point at thecontour.L971 Longitudinal ThreadThis cycle was created for longitudinal and lesstapered threads and is time optimized.Programming occurs like with L97.Differences to L97:R28pos. sign: degressive infeedneg. sign: constant infeedR34This parameter was inserted additionally. With thisparameter a retraction height of the tool over thethread can be programmed.Inside threads: 0,01 - 1 mmOutside threads: 0,01 - 3 mmD 26
