摘　　要：基于UG三维建模软件和AdvantEdge有限元仿真软件,对硬质合金立铣刀切削Ti-6Al-4V和Cr12进行切削仿真。通过改变刀具的螺旋角和前角,以切削力和切削温度作为评价标准来优化硬质合金立铣刀,进而改善切削难加工材料的性能。仿真结果表明:硬质合金立铣刀加工Ti-6Al-4V时螺旋角的合理范围为40°~45°,前角范围为8°~10°;硬质合金立铣刀加工Cr12时螺旋角的合理范围为35°~45°,其中以40°附近为最优,前角范围为15°~20°。Based on 3D modeling software UG and AdvantEdge finite element simulation software,cutting simulation of Ti-6Al-4V and Cr12 with carbide end mill was carried out.By changing the helix angle and rake angle of the cutting tool,the cutting force and cutting temperature were used as the evaluation criteria to optimize the cemented carbide end mill,so as to improve the performance of cutting difficult to cut materials.The simulation results show that the reasonable range of helix angle for Ti-6Al-4V with carbide end mill is 40°to 45°,the range of the front angle is 8°to 10°.The reasonable range of the helix angle for Cr12 with carbide end mill is 35°to 45°,the optimum range is around 40°,and the front angle range is 15°to 20°.
