摘　　要：在线电解修锐(electrolytic in-process dressing,ELID)磨削可以高效率地光整加工,而磁力研磨(magnetic abrasive finishing,MAF)具有柔性加工的特点。以三轴立式加工中心为平台,研发了一种结合ELID磨削与MAF的新型组合工艺。设计了ELID磨削工具和MAF工具头,提出了利用该组合工艺对复杂曲面进行加工的控制方法。分析了由于刀具磨损产生的工件形状误差,提出了误差补偿的措施,同时也讨论了避免加工干涉的方法。最后,开发出能同时适用于ELID磨削与MAF的复杂曲面光整加工控制与补偿软件。According to the high efficiency of ELID grinding and flexible machining characteristics of MAF, a new synergistic process integrated ELID grinding and MAF was developed based on a platform of three-axis vertical machining center. A grinding tool for ELID and a finishing tool for MAF were designed. Processing path control of synergistic process for complex surfaces were analyzed. The tool wear and the form error of work-piece were studied, and the methods for compensation and interference avoidance were also presented. Finally, A control and compensation software was developed and might be used to ELID grinding and MAF process for complex surface machining.
