摘　　要：以铣削玻璃纤维-碳纤维芳纶纸蜂窝板单因素试验条件为基础,研究切削参数对刀具磨损及加工质量的影响,分析菱齿化学气相沉淀(Chemical Vapor Deposition,CVD)金刚石薄膜涂层刀具(简称涂层刀具)的磨损机理,求出其后刀面磨损量的数学模型。结果表明:在其他切削参数不变的条件下,随着主轴转速n、铣削宽度ae的增大,或工件进给速度vf的减小,刀具后刀面磨损量VB均相应增大,且对玻璃纤维的加工质量影响显著;相比于硬质合金刀具,涂层刀具后刀面磨损量小,加工质量好,其磨损形式以磨粒磨损和涂层脱落为主。最后,对试验数据进行回归分析,得到涂层刀具后刀面磨损量的数学模型。Based on milling glass fiber-carbon fiber aramid paper honeycomb panel single-factor experiment, studied the influence of cutting parameters on tool wear and machining quality, analyzed wear mechanism of rhombohedral teeth Chemical Vapor Depo- sition（CVD） diamond film coated tools. And mathematical model of flank wear can be determined. The results show that：tool wear increased with the raising of spindle speed and milling width or the decreasing of feed speed. Meanwhile, the machining quality of glass fiber was influenced greatly by cutting parameters ; compared with cemented carbide tool, wear mass loss of coated tool is less, and its machining quality is better. The flank wear mainly consists of abrasive wear and coating peeling. Eventually, the mathematical model of coated tools＇ flank wear can be determined by regression analysis.
