摘　　要：以玻璃纤维增强复合塑料(GFRP)为试材,按照试验设计的切削速度(251.2、301.44、351.68、401.92、452.16 m/min)和进给速度(0.1、0.2、0.3、0.4、0.5 m/min),选用硬质合金刀具对GFRP进行了铣削开料试验,研究了切削速度和进给速度对铣削力、铣削温度和表面粗糙度的影响,并借助扫面电镜研究了GFRP表面损伤机理。结果表明:当增加切削速度时,铣削力和表面粗糙度逐渐降低,而铣削温度逐渐升高;当增加进给速度时,铣削温度升高、铣削力和表面粗糙度逐渐增大。均值分析得出进给速度对铣削力、铣削温度、表面粗糙度的影响大于主轴转速。GFRP表面损伤主要有树脂破坏和纤维破坏两种形式。The glass fiber reinforced composite plastic(GFRP)was used as the test material,according to the experimental design of the cutting speed(251.2,301.44,351.68,401.92,452.16 m/min)and feed rate(0.1,0.2,0.3,0.4,0.5 m/min),a carbide tool was selected to carry out milling test on GFRP,and the effects of cutting speed and feed rate on milling force,milling temperature and surface roughness were studied,and the surface damage mechanism of GFRP was investigated by scanning electron microscopy.The results show that the milling force and surface roughness decrease when the cutting speed increases,while the milling temperature increases gradually;the milling force,milling temperature and surface roughness increase gradually when the feed rate increases.The mean value analysis concludes that the influence of feed rate on milling force,milling temperature and surface roughness is greater than the spindle speed.The surface damage of GFRP is mainly in the form of resin damage and fiber damage.
