Micro-USM is used to fabricate complex micro-features in all brittle & hard materials. In micro-USM, both dimensional and form accuracy of machined component are depend on the shape of the tool & geometry. During machining, tool wear is an unavoidable phenomenon of micro-USM, which affect the accuracy of micro-feature. This article reports on a method named as rotary tool micro-USM to reduce tool wear. The rotary tool micro-USM involves abrasive slurry with providing simultaneous rotation and vibration to the tool. Rotation of the tool helped abrasives to replenish from the machining gap easily. Micro-channels were fabricated and characterized by using stereo microscope. From the results, it was found that rotary tool micro-USM resulted in very less tool wear and as a result of that micro-channels of better dimensional and form accuracy were developed.
