Influence of Workpiece Circumferential Speed in Wire Electrical Discharge Machining
(2013)Procedia CIRP ~ Proceedings of the Seventeenth CIRP Conference on Electro Physical and Chemical Machining (ISEM)In Wire Electrical Discharge Machining (WEDM) a specific wire run-off speed is applied to compensate wear and avoid wire breakage. Since the workpiece generally stays stationary and short discharge durations are applied, the relative displacement between wire and workpiece during one single discharge is very small. In Wire Electrical Discharge Dressing (WEDD), however, the workpiece rotates at very high circumferential speeds, since ...Conference Paper -
Applying Wire Electrical Discharge Dressing (WEDD) to Improve Grinding Performance of Metal Bounded Diamond Wheels
(2012)Procedia CIRP ~ Fifth CIRP Conference on High Performance Cutting 2012In order to improve grinding performance of metal-bonded diamond wheels, a proper conditioning method has to be used. In this work, wire electrical discharge dressing (WEDD) is evaluated. With a self-designed WEDD-device the dressing process can be carried out inside a grinding machine, reducing non-productive time. Moreover, the in-process WED-dressing was assessed, showing potential for future applications. Dressing experiments indicated ...Conference Paper -
Modeling and simulation of electrical discharge machining
(2012)Procedia CIRP ~ 1st CIRP Global Web Conference: Interdisciplinary Research in Production Engineering (CIRPE 2012)Electrical discharge machining involves complex physical processes occurring simultaneously, which lead to the removal of material from both electrodes. During the discharge, material melts, evaporates and is ejected when the plasma channel collapses. Modeling the erosion process can help to better interpret and predict results, which are otherwise difficult to understand. In this work, the material removal rate is predicted based on the ...Conference Paper
