钛合金铣削仿真分析及实验研究

摘要

由于良好的综合性能,钛合金被广泛应用,但钛合金加工性能差,刀具易磨损。为了提高钛合金铣削刀具寿命,设计正交实验,运用AdvantEdge FEM软件对TA15钛合金进行了三维铣削仿真,分析了切削温度与铣削参数之间的关系。基于铣削参数-温度图,并结合切屑云图,给出了优化后的铣削参数。铣削实验表明,仿真分析可以优化铣削参数,提高刀具寿命。%Titanium alloy is widely used for its good overall properties.But cutting performance of titanium alloy is low,and cutting tool is easily worn.In order to improve the life time of cutting tool,the orthogonal experiment is designed.The 3D milling simulation of titanium alloy TA15 is performed with AdvantEdge FEM software.The relationship between cutting temperature and milling parameters is analyzed.The optimized milling parameters are given based on the milling parameters-temperature graph and the chip breakage contour.Milling experiment shows that simulation analysis can optimize milling parameters and improve the life time of cutting tool.
