Analysis of stresses during exit in interrupted cutting with champfered tools

This paper presents an analysis of the stresses in the workpiece and tool during exit in interrupted cutting with chamfered tools. An elastic-plastic finite element model is developed to examine the stress fields in the workpiece for various chamfer forms and exit angles. Eight different cases are considered. The workpiece material considered is low carbon steel (203.4 N/mm2 yield stress). The geometric conditions considered include cases where …
