Influence of Electrical Resistivity and Machining Parameters on Electrical Discharge Machining Performance of Engineering Ceramics
Engineering ceramics have been widely used in modern industry for their excellent physical and mechanical properties, and they are difficult to machine owing to their high hardness and brittleness. Electrical discharge machining (EDM) is the appropriate process for machining engineering ceramics provided they are electrically conducting. However, the electrical resistivity of the popular engine...
متن کاملOptimization of Machining Parametric Study on Electrical Discharge Machining
Abstract—Productivity and quality are two important aspects that have become great concerns in today’s competitive global market. Every production/manufacturing unit mainly focuses on these areas in relation to the process, as well as the product developed. The electrical discharge machining (EDM) process, even now it is an experience process, wherein the selected parameters are still often far...
متن کاملReview on Micro Electrical Discharge Machining
Recent trend in reducing the size of products has given Micro Electrical Discharge Machining (MEDM) a significant amount of research attention. Due to the high precision, low tolerance and good surface quality that it can deliver, MEDM is potentially an important process for fabrication of micro-tools, micro-components and parts with micro-features. This paper briefs and highlights the various ...
متن کاملElectrical Discharge Machining of the Composites- a Literature Review
The use of unconventional machining techniques in shaping metal matrix composites (MMCs) has generated considerable interest as the manufacturing of complicated die contours. Metal matrix composites are advanced materials having high specific strength, good wear resistance, and high thermal expansion coefficient. Electrical discharge machining is a best process to make complicated shapes on the...
متن کاملCurrent Research Trends in Electrical Discharge Machining: A Review
EDM is an unconventional electro thermal machining process used for manufacturing geometrically complex or hard material parts that are extremely difficult-to-machine by conventional machining process. The process involves a controlled erosion of electrically conductive materials by the initiation of rapid and repetitive spark discharges between the tool and work piece separated by a small gap ...
