摘　　要：针对Waspaloy镍基高温合金难加工、效率低以及切削过程中难以直接获得观测数据的问题,基于AdvantEdge仿真平台建立了三维铣削模拟模型,分析切削力、切削温度以及刀具磨损的最佳铣削参数。结果表明:采用大的主轴转速n和小的每齿进给量f_(z)以及小的铣削深度a_p可以获得更小的切削力;铣削温度与n、f_(z)、a_(p)成正比;铣削力的最佳参数为n=7 000 r/min,f_(z)=0.06 mm/z,a_(p)=0.8 mm;铣削温度的最佳参数为n=7 000 r/min,f_(z)=0.07 mm/z,a_(p)=1.2 mm;最小磨损铣削参数为n=7 000 r/min,f_(z)=0.07 mm/z,a_(p)=1.2 mm。切屑随着n的增大碎片化程度增大。Aiming at the problems of waspaloy nickel-based superalloys difficult to process,low efficiency,and difficulty in obtaining observation data directly during cutting,a three-dimensional milling simulation model was established based on the AdvantEdge simulation platform.Analyze the best milling parameters for cutting force,cutting temperature and tool wear.The results show that using a large spindle speed n,a small feed per tooth fzand a small milling depth apcan obtain a smaller cutting force;the milling temperature is proportional to n,fz,ap;the best parameter of the milling force is n =7 000 r/min,fz=0.06 mm/z,ap=0.8 mm;the best parameter of milling temperature is n=7 000 r/min,fz=0.07 mm/z,ap=1.2 mm;the minimum wear milling parameter is n= 7 000 r/min,fz=0.07 mm/z,ap=1.2 mm.The chip fragmentation degree increases with the increase of n.
