Abstract

This paper presents new findings of a high speed filming investigation which reveals the actual mechanisms of chip flow, chip curl and chip breaking in metal machining. Variations in the modes of chip breaking (i.e. up-curling to side curling and vise versa) and the continuous change in chip curvature within a chip breaking cycle are shown as resulting from the effects of tool restricted contact, chip grove geometry and the cutting conditions, in orthogonal cutting. An approximate cutting force model presented in this paper calls for a need to extend the existing Conventional theories to include the effect of varying chip braking forces in machining of metals.
