摘　　要：切削力是铣削机理研究的重要对象,与刀具磨损和已加工表面质量等指标关系密切。本文通过软件ThirdWave建立了球头铣刀高速铣削模具钢Cr12MoV的仿真模型。该模型采用了网格自适应技术和删除技术。成功实现了切削力的高精度仿真,并对仿真模型进行了实验验证。模型分析了切入切出过程切削力的变化特性,同时也揭示了切削条件对切削力变化的影响规律。本研究成果可对切削工艺条件的合理选择提供借鉴。Cutting force is an importance research object of milling mechanism, and it is closely related to the tool wear and quality of the machined surface. In this study, we use the software ThirdWave to build simulation model of ball - end mill high - speed milling die steel Crl2MoV. The model realizes high precision simulation of cutting force successfully with the mesh adaptive technology and delete technology. It analyses the cutting force variation characteristics of cut - into and cut - out process, and it draws the effect of cutting conditions on cutting force. The results have great significance in the reasonable selection of cutting process conditions.
