Continuous electrical discharge machining (EDM) is characterized by random positions, uncertain energy, extremely short time, narrow tool-workpiece gaps, etc. Theoretical research into the mechanisms leading to thermal erosion of material and associated surface morphology has become urgent allow continued development application EDM technology. Firstly, multi-pulse theory geometric optimization...

Technological advances have facilitated many developments in the MEMS, electrical, medical and aerospace industries in recent years. As the devices commonly found in these industries have become smaller, so the requirements for high-precision machining techniques have become ever more pressing. Nowadays, micro-machining processes are playing an important role in satisfying these requirements. A...

in this work, the influence of different edm parameters (pulse current, pulse voltage, pulse on-time , pulse off-time) in finishing stage on  the surface roughness (r a )  as a result of application copper electrode to a workpiece( cold work steel  din1.2379)  has been investigated. design of the experiment was chosen as full factorial. statistical analysis has been done and artificial neural n...

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...

Micro-plate implants are jaw in the form of straight plates. The need for micro-plate Indonesia is quite high. Current fabricated using two machining processes, namely Wire Electrical Discharge Machining (wire-EDM) and micro-milling. These processes one reasons why price market expensive. One way to lower shorten implant manufacturing process. This research develops a process EDM die-sinking ma...
