Mechanics of Chip Formation

  • Jamal Y. Sheikh-Ahmad

The study of chip formation under controlled laboratory conditions gives an insight of how the work material is deformed and then removed ahead of a moving wedge-shaped tool. The simplified conditions of orthogonal machining used in studying chip formation makes it possible to gather information about chip shape and size, shear stress and strain in the chip, friction conditions, cutting forces, and cutting temperatures. Much work has been conducted over the past century to study the mechanics of chip formation in metal machining. As a result, metal machining is a well-established science and we generally have a very good idea how metal chips are formed and removed. Furthermore, the wealth of information and expertise in this field has allowed the advancement of metal machining theory to the level of astounding predictive capabilities. Naturally, similar techniques to those used in studying metal machining have been transferred to the study of composites machining but only limited...
