摘　　要：针对工程陶瓷传统磨削制孔存在表面质量较差等问题,对超声振动辅助加工及螺旋加工的工艺优势进行了归纳分析,提出了纵扭复合超声振动螺旋磨削制孔的加工方法。利用超声加工机床和白光干涉仪及马尔表面轮廓仪,对纵扭复合超声加工、纵向超声加工和普通磨削加工对孔表面质量的影响情况进行了研究;并进一步探究了施加纵扭复合超声振动后超声振幅、螺距、主轴转速、螺旋进给速度对加工孔表面质量的影响规律。研究结果表明:相比纵向超声加工和普通加工,纵扭复合超声加工有利于提高制孔表面质量;纵扭超声螺旋磨削加工超声振幅、螺距对孔底和孔壁表面粗糙度的影响趋势相似,主轴转速及螺旋进给速度对两者表面粗糙度的影响趋势总体上相反。Aiming at the problem of poor surface quality in the traditional grinding of engineering ceramics,the advantages of ultrasonic vibration assisted machining and helical machining were summarized and analyzed,and the machining method of longitudinal-torsional composite ultrasonic vibration assisted helical grinding was proposed.The experimental study on longitudinal-torsional composite ultrasonic,longitudinal ultrasonic machining and ordinary grinding effect on surface quality of hole condition was carried out by using ultrasonic machine and white light interferometer and Mahr surface roughness measuring instrument,and further explore longitudinal-torsional composite ultrasonic vibration assisted helical grinding of amplitude,thread pitch,feed rate,spindle speed for machining surface quality of hole.The results indicate that longitudinal-torsional composite ultrasonic vibration machining is beneficial to improve the surface quality of hole making compared with longitudinal ultrasonic machining and ordinary machining.The influences of ultrasonic amplitude and thread pitch on the surface roughness of hole bottom and hole wall are similar,while the influences of spindle speed and feed rate on the surface roughness of hole bottom and hole wall are generally opposite.
