Abstract

This paper reports the research carried out to study the machinability of austenitic stainless steel SS316 using textured tungsten carbide cutting tool under dry environment. Experiments were planned with different combinations of cutting speed, feed rate and depth of cut to study the dynamics of tool-chip interactions i.e. chip morphology and tool wear. A detailed investigation was conducted where chip thickness ratio and shear angle corresponding to twenty-seven experiments were studied. It was found that at a medium cutting speed (120 m/min), plastically deformed metal chips adhered over the tool nose along with notch wear. However, at low cutting speed (70 m/min), sever damage of tool observed over cutting nose observed. Under higher magnifications on electron microscope, chip deformed with lamellar structure at different level of segmentations are notable based on shear angle. It is recommended to machine SS316 with textured tools at higher cutting speed and feed rate, and moderate depth of cut.
