摘要
在总结国内外大量文献资料的基础上,利用自行研制的超声振动系统对碳纤维复合材料进行了磨削试验,研究不同加工参数对切削力和工件表面质量的影响,并对超声磨削机理进行了分析。结果表明:随着主轴转速的加快,切削力和表面粗糙度值减小;随着切削深度的增大或进给速度的加快,切削力和表面粗糙度值增大。与传统磨削加工相比,在加工参数相同的条件下,超声辅助加工时工件所受的切削力和表面粗糙度值更小。
On the basis of summarizing a lot of documents at home and abroad, a gnndmg test was carried out for the CFRP by use of the ultrasonic vibration system developed by ourselves in an attempt to find the impacts of different machining parameters to the cutting force and the surface quality of the work- piece. The results show that the cutting force and surface roughness value decrease with the increase of spindle speed, and the cutting force and surface roughness value increase with the increase of cutting depth or feed rate. If machining parameters are the same. the cutting force and surface roughness value of the work-piece under ultrasonic machining are smaller than those under conventional grinding.
