Analysis the effect of cutting speed on wear and crystal structure on CVD and PVD layer carbide insert materials

Abstract

Abstract It has been done analysis effect of cutting speed on wear and crystal structure on CVD and PVD layer carbide inserts has been performed. The purpose of the study was to determine the effect of cutting speed on wear, crystal size, dislocation density and micro lattice strain on CVD and PVD layer carbide insert materials to cut the AMS5643 stainless steel material. CVD and PVD layer carbide insert cutting process with cutting speed variation 113; 126; 140; 175 m/min with cutting motion of 0.38 mm/round and depth of cut 1.5 mm fixed. Wear test results showed that CVD layer carbide insert wear was 15% higher than PVD layer carbide inserts. The results showed that the size of CVD layer carbide insert crystals was smaller than PVD layer carbide inserts by 42% and the dislocation density of CVD layer carbide inserts made no significant difference to PVD layer carbide inserts, as well as micro lattice strains for CVD layer carbide inserts greater than PVD layer carbide inserts.
