本文用硬质合金刀具对Cu/PTFE复合材料进行了正交切削试验和仿真分析。采用等效均质模型实现三维切削仿真过程。通过与实验结果的对比，预测的切削力与实验结果吻合较好，偏差不超过20%。详细讨论了不同切削条件下加工参数与表面粗糙度的关系。结果表明，进给速度对表面粗糙度有显著影响，加工过程中应控制进给速度，以获得高的表面质量。通过对车削表面的观察，发现加工后的表面形貌中存在颗粒脱落、切断、挤压等现象。
In this paper, the orthogonal cutting experiment and simulation analysis of Cu/PTFE composite materials are carried out with cemented carbide tools. The equivalent homogeneous model is adopted to realize the three-dimensional cutting simulation process. Compared with the experimental results, the predicted cutting force is in good agreement with that of the experimental results, and the deviation does not exceed 20%. The relationship between processing parameters and surface roughness under different cutting conditions is discussed in detail. The results show that the feed rate has a significant effect on the surface roughness, and the feed rate should be controlled during the machining process to obtain high surface quality. Through the observation of the turning surface, there are phenomena such as particle pulled off, cut off, and pressed in the processed surface morphology.
