Regarding the following images of orthogonal cutting operations, briefly explain the conditions of workpiece material, tool material, rake angle, cutting speed, feed rate and depth of cut at which each type of chips are produced. (10 marks) Secondary shear zones Tool Chic Chip Tool Primary shear Workpiece - Primary shear zone BUE zone (a) continuous chip (b) continuous chip (c) built-up edge Low shear strain High - shear strain (d) segmented or (e) discontinuous chip
