摘要：切削力和切削温度是评价刀具切削性能的重要指标,也是影响刀具耐用度的关键因素。通过切削试验和切削仿真,对比分析了自主研发的硬质合金微槽车刀和原车刀的切削力和切削温度。结果表明:与原车刀相比,微槽车刀的主切削力降低了约5. 1%;进给抗力和切深抗力都有所增加,增幅分别为37. 5%和2. 1%;微槽的置入可增大温度分布曲线的局部波动性,并提高其整体平稳性。本文研究结论可为该硬质合金微槽车刀的后期研究提供理论支撑。
The cutting force and temperature are important indexes to evaluate the performance of turning tools, and are also the key factors affecting the tool life. Through cutting test and simulation, the cutting force and temperature of selfdeveloped micro-grooved carbide turning tools and the original turning tools are compared and analyzed. The results show that, compared with the original turning tool,the main cutting force of the micro-grooved turning tool is reduced by about 5.1%, and the feed resistance and depth resistance are increased by 37.5% and 2.1% respectively,and the insertion of the microgroove can increase the local fluctuation of the temperature distribution curve and while improving its overall stability. The research conclusion could provide a theoretical support for the later research of the micro-grooved carbide turning tool.
