Electrochemical grinding - WikipediaDeze pagina vertalen

Electrochemical grinding is a process that removes electrically conductive material by grinding with a negatively charged abrasive grinding wheel, an electrolyte fluid, and a positively charged workpiece. Materials removed from the workpiece stay in the electrolyte fluid. Electrochemical grinding is similar to electrochemical machining but uses a wheel instead of a tool shaped like the contour ...

INTRODUCTION WEDG (wire electro discharge grinding) technique is a special version of the micro WEDM method that was introduced firstly by Masuzawa et al. (1985) The WEDG process is considered as a finishing process where the purpose is to obtain good surface quality In WEDG no mechanical contact nor cutting is necessary for surface finish.

PDF Abstract. The objective of this work is to develop a finite element method (FEM) based mathematical model to simulate the hybrid machining process of grinding and electric discharge machining (EDM), named as Electro-discharge abrasive grinding (EDAG), for temperature distribution in the workpiece. Two different finite element codes have been developed to calculate the temperature ...
