在研究超声磁粒复合研磨工作原理基础上,结合传统磁粒研磨材料去除数学模型,探讨了超声振动对提高磁粒研磨效率的积极作用,揭示出主轴转速、供磁电流、加工间隙、超声功率等是影响超声磁粒复合研磨质量和效率的关键因素。运用现有数控铣床和工件表面精加工数控代码,结合软件技术设计了一套超声磁粒复合研磨加工工艺参数控制系统。实验证明,该控制系统可以实现自由表面超声磁粒复合研磨工艺参数的自动控制。

Based on the mechanical study of the ultrasonic magnetic abrasive finishing （UMAF） and analyzing the mathematics cutting model of the traditional magnetic abrasive finishing （MAF）, the effects of the ultrasonic vibration on the finishing efficiency of the traditional MAF was discussed. It has been found that the process parameters, the spindle speed, the ultrasonic vibration power as well as the gap between the magnetic pole and the work piece surface, were the key factors in deciding the finishing quality and efficiency of the UMAF. Then, with a numerical control machine and its NC codes for machining a free surface of a work piece, by the software and database technologies, a new control system was designed which could control the process parameters in the UMAF polishing proceeding. Finally, the experiments have showed that the system could implement the UMAF control automatically.
