Ti-6Al-4V titanium alloy (TC4) has been extensively applied in advanced manufacturing fields owing to its outstanding combination of mechanical properties and corrosion resistance. However, its poor machinability remains a critical challenge that limits further application. In this study, the effects of three categories of heat treatment processes, including annealing, solution treatment, and aging treatment, comprising eight specific heat treatment schemes, on the precision cutting performance of TC4 alloy were systematically investigated using DEFORM-3D numerical simulations. The results demonstrate that stress-relief annealing and full annealing effectively reduce cutting forces by up to... More >
