外文摘要：This study systematically investigates and compares the effects of three cutting techniques-ordinary cutting (OC), two-step cutting (TSP), and cryogenic laser-assisted cutting (CLAC)-on the cutting force, cutting temperature, chip morphol-ogy, and residual stress behavior in TC4 titanium alloy machining. Numerical simulation and experimental validation reveal that CLAC significantly optimizes the machining performance. Compared with OC, the cutting force and cutting temperature are reduced by 31% and 26%, respectively, and the surface roughness Sa value is reduced by 23.4% (from 0.432 to 0.331). TSP can reduce the cutting force and temperature by 25.5% and 11.6%, respectively, and improve the residual stress distribution and surface quality. CLAC performs best in chip shape control, surface compressive stress lift-ing and thermo-mechanical coupling management. Further analysis shows that laser power, cutting speed, cutting depth and other parameters have significant differences on cutting performance under different processes.
