超声加工（USM）通常用于加工硬脆材料。由于钢模具的抛光一直是业界严重关注的问题，为此开发了一种创新的具有成本效益的超声波抛光系统。超声波工具沿着有图案的路径移动以覆盖整个待抛光表面。在抛光表面观察到微切削、犁削和磨料压痕。以典型模具钢为试验对象，重点研究了磨料粒度和静载荷对表面光洁度的影响。根据抛光前的表面粗糙度确定最佳磨料尺寸。大静载荷的优点是磨料更有效地活化抛光。
Ultrasonic Machining (USM) is conventionally used for machining hard and brittle materials. As polishing of steel mold has been a serious concern in the industry, an innovative cost-effective ultrasonic polishing system is developed for this purpose. The ultrasonic tool moves in a patterned path to cover the entire surface to be polished. Microcutting, plowing and indentation by abrasives are observed on the polished surface. The experiment was conducted on typical mold steel with the emphasis on the effects of the abrasive size and the static load on the surface finish. The optimal abrasive size depending on the surface roughness prior to polishing is identified. Large static loads possess an advantage in that the abrasives are more effectively activated for polishing.
