中文摘要：

碳纤维复合材料具各向异性、导热系数低、磨削时热量易堆积,导致切削条件恶劣,严重影响工件表面质量.采用GC60J碳化硅砂轮平面磨削单向碳纤维复合材料,用热电偶在线测量磨削区域温度,分析不同工艺参数下磨削温度的变化规律以及磨削热对试件加工质量的影响.试验结果表明：切削速度、磨削深度和工件进给速度的增大都会引起磨削温度的升高;磨削热对磨削表面质量有不利的影响,导致磨削表面纤维脱粘、烧伤等现象,使得磨削表面质量恶化.

英文摘要：

The anisotropy,low thermal conductivity and grinding heat of carbon fiber reinforced plastics make machining and surface quality bad.Surface grinding experiments of uni-directional carbon fiber reinforced plastics were carried out using GC60J silicon-carbide abrasive wheel,and the surface temperature of the grinding area was detected online by use of the thermocouple.The rule of surface grinding temperature and the effect of the grinding heat on the surface quality in the condition of different technological parameters were discussed.The experimental results show that the surface grinding temperature increases with the rising of the grinding speed,the grinding depth and the feed speed of workpiece.The grinding heat has a bad influence on the surface quality,such as the fiber pull-out and burning which makes the surface quality worse.
