摘　　要：为了探索汽轮机低压锁扣叶片钛合金的清洁切削加工规律,优化其切削参数,保证表面质量,提高切削效率,采用均匀设计方法设计了钛合金切削试验参数。分别在常温干式切削和低温冷风降温切削条件下,对切削力和表面粗糙度进行了试验研究,对试验数据进行多元线性回归分析,建立了适用于钛合金清洁加工的表面粗糙度和切削力多元线性回归模型,在此基础上建立了针对表面粗糙度、切削力和切削效率为目标的切削参数多目标优化模型,对切削参数进行了优化和验证,优化效果明显。相对过去生产实际的切削参数,在保证表面粗糙度要求的前提下,常温干式切削效率提高21.9%,低温冷风降温切削效率提高20.3%。In order to explore clean cutting rules,to optimize cutting parameters,and to improve cutting efficiency of turbine low-voltage lock blade material,cutting parameters are designed by means of uniform design method.The cutting forces and surface roughness are studied under the condition of dry cutting and cold blast machining.Multi-objective optimization model of cutting force and surface roughness applied to Titanium alloy clean cutting have been established by multiple regression analysis.Optimization results show that,through the optimization and validation of cutting parameters,cutting efficiency is improved by 21.9% and 20.3% for dry cutting and cold blast machining under the condition of required surface roughness,compared with the actual cutting parameters of past production.
