摘　　要：为探索高硅氧玻璃纤维/酚醛树脂复合材料的切削加工性能,对该类材料进行大直径薄壁回转类零件的车削加工。采用四种不同刀具进行实验研究,获得了不同切削参数及不同刀具材料对切削力的影响规律。试验结果表明:切削用量三要素中,切削深度对切削力的影响最大,其次是进给量,而切削速度的影响很小。当切削速度为119.32 mm/min、进给量为0.1 mm/r、背吃刀量为0.5 mm时,为最优切削参数。Ti-Al-Si-N纳米涂层硬质合金和超硬材料F2HX无涂层硬质合金刀具适合于低速加工,而PCD刀具则适合于高速加工。In order to investigate the machinability of high silica glass fiber/phenolic resin composites,the turning process of the large diameter thin-wall rotary parts is carried out.The experiment was done with four kinds of cutting tools,the effects of different cutting parameters and cutting tool materials on cutting force are obtained. The results demonstrate that in three cutting parameters,cutting depth has the greatest influence on cutting force,followed by cutting feed,and the cutting speed is very small. The optimal cutting parameters can be obtained when v =119. 32 mm/min,f = 0.1 mm/r and ap= 0.5 mm. Ti-Al-Si-N nano coated carbide and super-hard material F2HX uncoated carbide tools are suitable for cutting the material at the low cutting speed,the PCD tool is suitable for high speed machining.
