TL;DR: In this article, the authors investigated the effect of chip thickness and grinding speed on the morphology of grinding traces and chips, and found that when the chip shape changes from serrated fracture to banded continuity, and the frequency of adiabatic shear slip goes up with the increase of grinding speed, which helps to reduce the grinding force, making the grinding process more stable.
