WebFeb 12, 2012 · The geometry of the transition surface bounded between S α and S γ changes significantly when the disparity of S α and S γ is considerable. In this case larger value of one parameter relative to the other leads to the formation of a relative plane transition surface whereas equal values of the two parameters results in curved transition ... WebJan 1, 2016 · Chip formation in gear shaping is very complex, despite the fact that the cutting speed and feedrates are typically kept constant. This is due to varying cutter–workpiece engagement (CWE) conditions arising from the gear generative motion, and prior cutting history. The toothed profile of the cutter can also result in multi-flank …
