以涂层硬质合金刀具对铸钢轴箱体轴承孔精镗实验为基础,采用多因素正交试验对刀具寿命进行研究,反复调整切削参数并用有限元分析软件对切削过程进行模拟,得出了最小表面磨损率和所对应的最佳切削速度及温度,建立了刀具寿命的经验模型,为进一步研究刀具优化和切削参数、提高刀具寿命等方面提供了理论基础。
Based on the fine boring experiment of the bearing hole of the cast steel shaft with the coated cemented carbide tool, the multi-factor orthogonal test was used to study the tool life. The cutting parameters were adjusted repeatedly and the cutting process was simulated by the finite element analysis software. The minimum Surface wear rate and the corresponding optimum cutting speed and temperature, established an empirical model of tool life, which provides a theoretical basis for further research on tool optimization and cutting parameters and tool life.
