摘要
TC4钛合金在铣削加工过程中面临切削力大、切削温度高、工件残余应力大以及加工表面质量难控制等问题,属于典型的难加工材料。本研究基于ABAQUS软件对TC4钛合金切削过程进行仿真分析,采用Johnson-Cook模型作为工件材料的本构模型进行有限元模拟研究。在模拟切削过程中,通过改变切削速度v c,研究其对刀具切削力、工件残余应力、温度场、表面质量以及所产生的切屑形貌的影响规律。此外,通过ABAQUS软件模拟锯齿切屑的形成机理,并探讨切削深度对切削过程的作用机制等复杂问题。研究结果能准确预测切削过程,为优化切削参数提供理论依据,并在实际加工中建议合适的切削速度,以提高加工质量和效率。
The TC4 titanium alloy was a typical difficult-to-process material due to problems such as the large cutting force,the high cutting temperature,the large residual stress and difficult to control surface quality during milling.The cutting process of TC4 titanium alloy was simulated and analyzed based on ABAQUS software,and the Johnson-Cook model was used as the constitutive model to conduct the finite element simulation research.In the simulation cutting process,the effect of cutting speed v c on the cutting force,residual stress,temperature field,surface quality and chip morphology was studied by change the speed v c.In addition,the formation mechanism of sawtooth chips was simulated by ABAQUS software,and complex problems such as the effect of cutting depth on cutting process were discussed.The research result could accurately predict the cutting process,provide theoretical basis for optimizing the cutting parameters,and suggest the appropriate cutting speed in the actual processing to improve processing quality and efficiency.
