摘　　要：针对某一典型吸波蜂窝材料,采用粉碎齿刀具在不同切削参数下进行高速铣削试验,从切削力、加工表面质量、切削功率、切削温度等角度分析铣削参数对加工过程参量的影响规律,进而确定吸波蜂窝高速铣削的优化工艺参数。研究表明,提高切削速度有利于降低切削力和改善表面加工质量,当进给速度、切削深度或切削宽度增大时,因单位时间内材料切除体积增大,导致切削力和切削温度升高,造成表面缺陷加剧。以抑制毛刺缺陷形成为主要目标时,综合考虑工艺参数对切削力、切削功率和切削温度的影响,推荐优化工艺参数为主轴转速16000 r·min^(-1)、进给速度4000 mm·min^(-1)、切削深度10 mm和切削宽度15 mm。研究结果可为粉碎齿刀具高速铣削吸波蜂窝材料的工艺优化提供数据参考。This paper performs high-speed milling experiments on a typical wave-absorption honeycomb with crushed-tooth cutter under varied cutting parameters.The effects of cutting process on such parameters as cutting force,machined surface quality,cutting power,and cutting temperature are investigated.Then the optimized cutting parameters for high-speed milling of wave-absorption honeycomb are determined.The results indicate that the increase in cutting speed can help to decrease the cutting force and promote the machined surface quality.Meanwhile,the increase in feed speed,cutting depth,or cutting width causes the increase in specific material removal volume,which leads to higher cutting force and cutting temperature as well as severer machined surface defects.Taking the burr defects suppression as the main machining target and giving an overall consideration for the above other parameters,the optimized cutting parameters are recommended as the spindle speed of 16000 r·min^(-1),feed speed of 4000 mm·min^(-1),cutting depth of 10 mm,and cutting width of 15 mm.The research can provide guidances for selection of cutting parameters during high-speed milling of waveabsorption honeycombs.
