Experimental Investigation on the Ultrasonic Mill-grinding of Engineering Ceramic Material

对陶瓷材料的超声铣磨加工系统的结构与工作原理进行分析,并采用超声振动实验系统对陶瓷材料进行超声磨削加工正交实验,研究不同工艺参数对超声加工陶瓷材料表面粗糙度的影响。实验表明:与传统机械加工相比,超声加工能够使工件的表面粗糙度值降低;当振幅最大、主轴转速最大、进给速度最小、切深最小时,得到的加工表面粗糙度值最小;加工参数对粗糙度值影响大小依次为:进给速度、主轴转速、振幅和切削深度。

In this paper,the ultrasonic mill-grinding system for ceramic materials is analyzed on its structure and working principle. An orthogonal experiment on the ultrasonic mill-grinding of the ceramic material was carried out by ultrasonic vibration system. The effects of processing parameters on the surface roughness of ground ceramic materials were investi-gated by experiments. The results show that,compared with traditional machining,ultrasonic mill-grinding can reduce the surface roughness of the workpiece;the smallest surface rough-ness value can be obtained with the maximum amplitude,maximum spindle speed,minimum feed rate,minimum depth of cutting;The influence order of machining parameters on the roughness value is：feed speed,spindle speed,amplitude and cutting depth.
