摘要
为研究镁基碳纤维增强复合材料(C_f/Mg)的切削力与已加工表面质量,开展了硬质合金铣刀与硬质合金钻头超声辅助切削试验研究。通过正交试验得到,超声辅助铣削C_f/Mg复合材料时铣削力随每齿进给量及铣削深度的增加而明显增大,随主轴转速的增加而减小;试验中,在超声辅助铣削时每齿进给量0.025mm、铣削深度0.2mm、转速6000r/min加工参数下铣削力最小,每齿进给量0.025mm、铣削深度0.2mm、转速4000r/min加工参数下表面质量较好;采用硬质合金钻头进行单因素钻削试验时,轴向钻削力随主轴转速的升高而减小;与传统钻削相比,超声辅助钻削能减小轴向钻削力,在机床转速6000r/min、机床进给速度100mm/min加工参数下超声辅助钻削相比传统钻削可减小约36%的轴向钻削力;超声辅助钻削相比传统钻削能改善钻孔出口的毛刺、分层等缺陷。
This paper aims to study the machinability of carbon fiber reinforced Mg-matrix composite(C_f/Mg), the ultrasonic assisted cutting experiments of carbide milling cutters and carbide drill bits are carried out. Through orthogonal test, it is found that the milling force of ultrasound-assisted milling C_f/Mg composite increases with the increase of feed and milling depth of each tooth, and decreases with the increase of spindle speed. In the test, when ultrasonic assisted milling is carried out, the feed per tooth is 0.025 mm, the milling depth is 0.2 mm, and the milling force is the minimum under the processing parameters of 6000 r/min. The feed per tooth is 0.025 mm, the milling depth is 0.2 mm, and the surface quality under the processing parameters of 4000 r/min is relatively good. When single factor drilling test is carried out with carbide bit, the axial drilling force decreases with the increase of spindle speed. Compared with traditional drilling, ultrasonic assisted drilling can reduce the axial drilling force. Compared with traditional drilling, ultrasonic assisted drilling can reduce the axial drilling force by about 36% when the machine speed is 6000 r/min and the feed speed of the machine is 100 mm/min. Compared with traditional drilling, ultrasonic assisted drilling can decrease burr and stratification at the drilling exit.
