基于高速切削理论建立了切削钛合金TC4的铣削力理论模型,进行了铣削力有限元仿真分析,并开展了正交铣削实验,获得了刀具尺寸一定时高速切削情况下主轴转速n、每齿进给量fz、轴向切深ap对铣削力的影响规律.结果表明,与普通切削情况相似,轴向切深ap对铣削力影响最大;以铣削力望小与材料去除率望大为目标,使用Pareto模拟退火算法对切削参数进行多目标优化,得到了使铣削力较小的同时材料去除率较大的解集,并通过铣削实验验证了最优解的可行性.
Analysis and Optimization of Titanium Alloy Cutting Parameters based on High-speed Milling
Based on the high speed cutting theory,a theoretical model of cutting titanium alloy TC4 was established. Also,the finite element simulation analysis as well as orthogonal milling experiments were carried out. The influence of the spindle speed n,feed en-gagement fz,and axial cutting depth ap on cutting force was obtained. The results showed that similar to the conventional cutting situa-tion,the axial cutting depth ap plays the biggest role in affecting the milling force. With the milling force and the material removal rate,the cutting parameters were optimized by the solution set with the material removal rate,and the feasibility of the optimal solution was verified through the milling experiment.
