表面处理操作是制造周期中成本高昂且至关重要的一部分。超声波抛光是超声波加工的一种新形式，已成功应用于有限的应用领域，作为一种灵活、可控的精加工工艺显示出巨大的前景。然而，需要进行研究，以开发该过程的必要知识和技术基础，以充分发挥其潜力。本文介绍了一项与电火花加工（EDM）工件表面完整性改善相关的超声波抛光参数的研究结果。

SURFACE FINISHING OPERATIONS REPRESENT A COSTLY AND CRITICAL PORTION OF THE MANUFACTURING CYCLE. ULTRASONIC POLISHING, A NEW VARIANT OF ULTRASONIC MACHINING, HAS BEEN SUCCESSFULLY UTILIZED IN LIMITED APPLICATIONS AND SHOWS GREAT PROMISE AS A FLEXIBLE, CONTROLLABLE FINISHING PROCESS. HOWEVER, RESEARCH IS REQUIRED TO DEVELOP THE NECESSARY KNOWLEDGE AND TECHNOLOGY BASE OF THE PROCESS TO REALIZE ITS FULL POTENTIAL. THIS PAPER PRESENTS THE RESULTS OF AN INVESTIGATION OF THE ULTRASONIC POLISHING PARAMETERS RELATED TO SURFACE INTEGRITY IMPROVEMENT FOR ELECTRICAL DISCHARGE MACHINED (EDM) WORKPIECE.
