摘要：钛合金环槽铆钉因其高的铆接强度及良好的防松性能被广泛应用于航空航天行业。钛合金切削性能差,切槽刀具工作环境恶劣,使得切槽车刀的磨损更加严重。以钛合金环槽车削加工为研究对象,运用数值方法,得到不同的切削速度、进给量参数下,钛合金车削加工环槽时硬质合金刀具后刀面的磨损速率。通过数据分析,建立刀具后刀面磨损速率预测模型,利用最小二乘法进行参数辨识。应用遗传算法对考虑刀具后刀面磨损速率和切削加工效率的双目标进行优化,得到最优工艺参数组合。结果表明,经过优化的工艺参数,使整体目标值提高了2.9%。
Titanium （Ti） alloy ring groove rivet has been widely used in the aerospace industry due to its excellent riveting inten- sity and anti-looseness. The grooving tool wear is more serious owing to the bad performance of Ti alloy machining and too! working environment is poor. Research is carried out on the machining process of Ti alloy ring groove as an object. The wear rate of rear face of grooving carbide tool was obtained in different cutting speed and feed rate parameters by using numerical method during cutting of Ti alloy ring groove. The tool rear face wear rate prediction model was established based on the data analysis, and the parameters identifi- cation was carried out by the least square method. Genetic algorithm was applied to consider double objective optimization for tool rear face wear rate and machining efficiency, and the optimal combination process parameters was obtained. The results show the overall tar- get value is increased by 2.9% after optimization of the process parameters.
