超声辅助磨削碳纤维复合材料的工艺试验研究

Experimental study on ultrasonic assisted grinding of carbon fiber composites

对碳纤维复合材料的超声辅助磨削工艺特性进行试验研究,首先进行超声振幅与工件表面质量影响关系的单因素试验,然后对工具粒度、进给速度、磨削深度和主轴转速与工件表面质量的影响关系进行正交试验分析,最后对优化的加工参数进行试验验证。采用优化的工艺参数组合进行树脂基碳纤维复合材料加工,显著提高了工件的表面质量。

Experimental study on ultrasonic assisted grinding technology of carbon fiber composites was carried out. Firstly,the single factor experiment of the relationship between the ultrasonic amplitude and the surface quality of the workpiece was carried out. Then the orthogonal experiments were carried out to analyze the influence of tool size,feeding rate,grinding depth and spindle speed on the surface quality of workpiece. Finally,the optimized machining parameters were tested and verified. The resin matrix carbon fiber composite material processed by the optimized process parameters has remarkably improved surface quality.
