Ultrasonic Vibration Assisted Electro-Discharge Machining
An ultrasonic vibration has been superposed on the normal electrode movement to increase the flushing effect during a micro electro-discharge machining (EDM) process. A systematic study on the effects of ultrasonic vibration on the EDM performance for fabricating microholes in Nitinol has been completed. The introduction of ultrasonic vibration to the microEDM process has more than 60 times inc...
متن کاملUltrasonic Machining at the Nanometer Scale
Experiments on Highly Oriented Pyrolytic Graphite (HOPG) demonstrate that ultrasonic-assisted actuation with the tip of an Atomic Force Microscope (AFM) cantilever can induce stacking modifications and folding of triangular-shaped HOPG surface flakes. We have generated permanent displacements of buried dislocations that require stacking changes of extended graphene layers by repeatedly scanning...
متن کاملAn Experimental Investigation on Surface Roughness and Edge Chipping in Micro Ultrasonic Machining
Surface quality including surface roughness and edge chipping is a key process measure in micro ultrasonic machining (Micro-USM) as an efficient process for micromachining of hard and brittle materials. Process parameters such as ultrasonic vibration amplitude, static load, type of tool material, type and size of abrasive particles and slurry concentration can influence the surface quality. How...
متن کاملAn investigation into the machining characteristics of titanium using ultrasonic machining
This paper presents a review on the problems encountered in machining titanium and application of USM in machining titanium and its alloys. Experiments have been conducted to assess the effect of three factors-tool material, grit size of the abrasive slurry and power rating of ultrasonic machine on machining characteristics of titanium (ASTM Grade I) using full factorial approach for design and...
متن کاملRotary ultrasonic machining of ceramics: design of experiments
Rotary ultrasonic machining is one of the nontraditional machining processes for advanced ceramics. Currently available in literature are publications on theoretical and experimental studies on material removal rates in rotary ultrasonic machining. However, there is no report on the systematic study of the cutting force in rotary ultrasonic machining. Furthermore, the effects of some process pa...
