Batch Mode Micromanufacturing Based on Micro Electro-discharge Machining and Micro Ultrasonic Machining for Micro Electro Mechanical Systems (mems)
Metal alloys have material properties that are very appealing for micro electro mechanical systems (MEMS), but present a challenge for process integration within a lithographic manufacturing sequence of the type used in the semiconductor industry. The batch-mode micro electrodischarge machining (μEDM) discussed here uses lithographically-fabricated electrode arrays with high density and high un...
متن کاملUltrasonic 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 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 کاملMachining as a mechanical property test revisited
Smith, David L. MSIE, Purdue University, May 2015. Machining as a Mechanical Property Test Revisited. Major Professor: Srinivasan Chandrasekar. There is much need for data on mechanical behavior of metals at high strains and strain rates. This need is dictated by modeling of processes like forming and machining, wherein the material in the deformation zone is subjected to severe deformation con...
