Abstract

Material microstructures have significant effects on the mechanical property of the titanium alloy, so the material removal behaviour highly depends on its microstructures. In this paper, effects of equiaxial and martensitic microstructures on material removal behaviour were investigated in the ultraprecision machining of Ti6Al4V alloys from the viewpoint of energy consumption. The material removal rate (MRR), material removal energy and specific cutting energy (SCE) were theoretically and experimentally analyzed in the machining. Results show that the MRR of the equiaxial and martensitic alloys is almost same, but the material removal energy and SCE of the martensitic alloy are smaller in comparison to the equiaxial alloy. Besides, effects of MRR on the material removal energy are discussed in machining of the martensitic alloy.
