WebNov 2, 2015 · i know that when the stepover is less than 50% that the feed can increase to keep the same chip thickness (chip thinning). i was hoping someone would have the formula for the sfm increase if you can get any? the seco salesman in my area had a formula, but he has moved. i looked on seco's website but cant find anything. any help … WebThe ideal chip shape is small and breaks free early, carrying heat away from the tool and work. Threads per inch (TPI) for taps, die heads and threading tools. Cut Width. Any time the width of cut is less than half the diameter, a geometric phenomenon called Chip Thinning reduces the actual chipload.

The first part of cutting the slot is full diameter of the tool but on the way back the radial depth of cut is .25 so I use the chip thinning formula and my increased my feed.
WebWith 90 degree cutters the feed per tooth equals the maximum chip thickness ( fz = hex ). When decreasing the entering angle, increase feed per tooth to make sure to keep the same chip thickness. KAPR=90° KAPR=45° KAPR=10° Example: If maximum hex = 0.1 mm and KAPR = 45° Recommended feed, fz = 1.4 x 0.1 = 0.14 mm/tooth
