Chip thickness ratio r is always

Webchip thickness after the cut (t 2) is always greater than the chip thickness before the cut (t 1), ∴ r is always < 1, i.e. the uncut chip thickness value is less than the chip thickness … WebThe minimum chip thickness depends on the cutting edge radius, workpiece material, and the micro-cutting of steel. For example, Vogler et al. [7] conducted finite element (FE) simulation of the micro-cutting of steel, finding that the minimum chip thickness is 20% and 30% of the cutting edge radius for the pearlite and ferrite, respectively. However, …
