Electro Discharge Machining Of Aluminium Alloy (LM6)-5 wt.% SiCp Composites Using Copper Electrodes
Metal matrix composites (MMCs) are now gaining their usage in aerospace, automotive and biomedical industries because of their inherent properties like high strength to weight ratio, low wear rate etc. To machine these types of materials conventional machining methods are unsuitable because of high tool wear and tooling cost. Electro discharge Machining (EDM) is one of the important nontraditio...
متن کاملSurface Studies of Electrodes Used in Spark
Protrusions on the surfaces of electrodes used in high voltage spark gaps lead to local field enhancements, which lower the self-breakdown voltage of the spark gap. Stainless steel, brass, and copper-tungsten electrodes have been tested in a 5-30 kV, 4-25 kA, .1.6 Caul/shot, unipolar, pulsed spark gap with N2 gas or air. The heights and bases of variously shaped protrusions on the surfaces of t...
متن کاملProcess capability improvement through DMAIC for aluminum alloy wheel machining
This paper first enlists the generic problems of alloy wheel machining and subsequently details on the process improvement of the identified critical-to-quality machining characteristic of A356 aluminum alloy wheel machining process. The causal factors are traced using the Ishikawa diagram and prioritization of corrective actions is done through process failure modes and effects analysis. Proce...
متن کاملParameters for Fabricating Nano-Au Colloids through the Electric Spark Discharge Method with Micro-Electrical Discharge Machining
In this study, the Electric Spark Discharge Method (ESDM) was employed with micro-electrical discharge machining (m-EDM) to create an electric arc that melted two electrodes in deionized water (DW) and fabricated nano-Au colloids through pulse discharges with a controlled on-off duration (TON-TOFF) and a total fabrication time of 1 min. A total of six on-off settings were tested under normal ex...
متن کاملElectro - discharge machining of mesoscopic parts with electroplated copper and hot - pressed silver tungsten electrodes ∗
Recent advances in the development of plasma etchers for silicon has brought machines to the market which are able to etch silicon with high etch rates (>5 μm min−1) at high anisotropy (taper of sidewalls <1.5◦). Micromachined silicon is therefore not only suitable for applications in micromechanics but it can also fill the gap which exists between conventional macromachining (milling, turning)...
