摘要
为提高钛合金材料的精密加工性能,采用模拟与试验验证相结合的方法,深入研究钛合金材料Ti6Al4V的精密切削过程,并建立钛合金切削的正交有限元模型,获得切屑形成过程、切削力曲线、温度及应变分布等结果。结果表明:数值模拟与试验相吻合;切削参数对切屑形态有重要影响,切屑形状均为锯齿状。为钛合金的精密切削机理研究提供一定基础。
To improve the machinability in the precision turning process of the titanium alloy Ti6 Al4 V,the precision turning process was studied by combining simulation with experiment validation,and an orthogonal cutting finite element model was established.The chip formation,cutting force and cutting temperature were obtained.The results show that the result of simulation agrees well with the result of experiment,the cutting parameters have important influence on the serrated shape,and the chip shape is serrated.This paper provides a basis for the study of precision cutting mechanism of titanium alloy.
