The thread advance can be used if you wish to begin theindividual cuts slightly earlier in order to produce a precise start of thread as well.Thread run-in (inc)The thread run-in can be used if you cannot approach the thread from the side andinstead have to insert the tool into the material (e.g. lubrication groove on a shaft).Thread run-in = thread run-out (inc)mmmmmmLR Thread run-out (inc)The thread run-out can be used if you wish to retract the tool obliquely at the endof the thread (e.g. lubrication groove on a shaft).mmH1 Thread depth (inc) mmInfeed slope as flank (inc) – (alternative to infeed slope as angle)DP > 0: Infeed along the rear flankDP < 0: Infeed along the front flankDPorαP Infeed slope as angle – (alternative to infeed slope as flank)α > 0: Infeed along the rear flankα < 0: Infeed along the front flankα = 0: Infeed at right angle to cutting directionIf you wish to infeed along the flanks, the maximum absolute value of thisparameter may be half the flank angle of the tool.DegreesInfeed along the flankInfeed with alternate flanks (alternative)Instead of infeed along one flank, you can infeed along alternate flanks to avoidloading the same tool cutting edge at all times, and thus increase the tool life.α > 0: Start at rear flankα < 0: Start at front flankD1 or ND(only for ∇ and∇ + ∇∇∇)First infeed depth or number of roughing cutsThe respective value is displayed when you switch between the number ofroughing cuts and the first infeed.mm
