铣削作为一种常用的加工方法,广泛应用于各种材料的粗加工和精加工。本文根据铣削过程中产生的铣削温度,建立了工件铣削时的热分布系数公式。利用DEFORM-3D有限元软件对零件进行了正交切削仿真,研究了不同加工参数对铣削热分布系数的影响,确定了最佳加工参数,并进行了铣削温度实验,验证了仿真温度。实验结果表明,模拟温度与实验温度非常接近,误差很小,验证了该方法的准确性。同时,还研究了不同的工件初始温度对磨削力和稳定性的影响。结果表明,适当的加热可以有效提高薄壁零件的铣削稳定性。
Milling, as a common machining method, is widely used in rough machining and final finishing of various materials. In this paper, according to the milling temperature produced in the milling process, the formula of heat distribution coefficient for workpiece milling is established. By means of Deform-3D finite element software to carry out orthogonal cutting simulation of workpiece, the influence of different machining parameters on milling heat distribution coefficient is studied, the optimal machining parameters are determined, and the milling temperature experiment is carried out to verify the simulation temperature. The experimental results show that the simulation temperature is very close to the experimental workpiece temperature, and the error is very small, which verifies the accuracy of the method. At the same time, the influence of different initial temperature of workpiece on the milling force and stability is also studied. The results show that proper heating of the workpiece can effectively improve the milling stability of the thin-walled parts.
