切削参数对TC11钛合金曲面铣削性能的影响OA

Using the single-factor control variable method,curved surface milling experiments on TC11 titanium alloy were conducted to investigate the effects of four independent factors—cutting speed,feed per tooth,cutting depth,and stepover—on cutting force,cutting temperature,and surface quality during curved surface milling.The experimental results indicate that feed per tooth is the main influencing factor on the resultant radial force,while cutting speed has the least influence.Feed per tooth has the greatest impact on cutting temperature,whereas cutting depth has the smallest influence.The main influencing factor on surface roughness is stepover;a smaller stepover combined with a larger feed per tooth can achieve lower surface roughness.Better surface quality is obtained under the cutting parameters of V=80 m/min,fz=0.04 mm/z,ap=0.25 mm,and ae=0.1 mm.
