Programming technology functions (cycles)8.1 DrillingTurning292 Operating Manual, 03/2013, 6FC5398-8CP40-3BA1Parameter Description UnitDF Infeed:• Amount for each additional infeed• Percentage for each additional infeedDF = 100%: Infeed increment remains constantDF < 100%: Infeed increment is reduced in direction of final drilling depth.Example: last infeed was 4 mm; DF is 80%next infeed = 4 x 80% = 3.2 mmnext infeed = 3.2 x 80% = 2.56 mm etc.mm%V1 Minimum infeed - (only for DF in %)Parameter V1 is only available if DF< 100 has been programmed.If the infeed increment becomes very small, a minimum infeed can be programmed inparameter "V1".V1 < Infeed increment: The tool is inserted by the infeed incrementV1 > Infeed increment: The tool is inserted by the infeed value programmed under V1.mmV2 Retraction distance after each machining step – (for chipbreaking only)Distance by which the drill is retracted for chipbreaking.V2 = 0: The tool is not retracted but is left in place for one revolution.mmLimit distance (forswarf removalonly)• ManualThe limit distance must be entered manually.• AutomaticThe limit distance is calculated by the cycle.V3 Limit distance – (for swarf removal only and manual limit distance)Distance to the last infeed depth that the drill approaches in rapid traverse after swarfremoval.mmDTB (only for Gcode)• Dwell time at drilling depth in seconds• Dwell time at drilling depth in revolutionssrevDT • Dwell time at final drilling depth in seconds• Dwell time at final drilling depth in revolutionssrevDTS (only for Gcode)• Dwell time for swarf removal in seconds• Dwell time for swarf removal in revolutionssrev
