Abstract

Cutting force variation in machining has been associated with machine tool chatter, mode of chip formation and variable undeformed chip thickness. In ultra-precision machining, the variation in microcutting force has its origin in the changing crystallography of the material being cut. A physical model is presented to predict the pattern of micro-force variation when crystals of different crystallographic orientations are being machined. Methods for minimizing the cutting force fluctuation in polycrystalline materials are discussed.
