摘　　要：采用激光增材制造TC4钛合金零件在不能满足加工精度和表面粗糙度要求时,还需应用铣削等切削方法进行加工,从而满足其使用要求。以切削速度、每齿进给量、铣削深度为优化设计变量,切削力为响应性能指标,运用Box-Behnken方法设计出曲面响应法的试验方案,建立出铣削激光增材制造TC4钛合金的响应模型。通过对切削力两个回归模型进行显著性分析,P值<0.0001、校正系数R^(2)=0.9908≈1,表明该模型的可靠性较高。参数优化发现铣削参数对切削力的影响顺序为:铣削深度>切削速度>每齿进给量。通过运用曲面响应法的多目标优化,得到以切削力最小为优化目标最优铣削参数组合为切削速度v_(c)=55 m/min,每齿进给量f_(z)=0.04 mm/z和铣削深度a_(p)=0.3 mm。When the laser additive manufacturing of TC4 titanium alloy parts can not meet the processing accuracy and surface roughness requirements,it is also necessary to apply milling and other cutting methods for processing,so as to meet its use requirements.With cutting speed,feed per tooth and milling depth as the optimal design variables and cutting force as the response performance index,the experimental scheme of surface response method was designed by Box-Behnken method,and the response model of milling laser additive manufacturing TC4 titanium alloy was established.Through the significance analysis of the two regression models of cutting force,the P-value<0.0001、correction coefficient R^(2)=0.9908≈1.Through parameter optimization,it was found that the order of influence of milling parameters on cutting force is:milling depth>cutting speed>feed per tooth.Through the use of surface response method of multi-objective optimization.The optimal combination of milling parameters with minimum cutting force was obtained as cutting speed v_(c)=55 m/min,feed rate per tooth f_(z)=0.04 mm/z and milling depth a_(p)=0.3 mm.
