Wire Electrical Discharge Grinding SlideShare

02/04/2017 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.
