Experimental investigation on low speed wire electrical discharge turning and its application in fabricating micro parts

Abstract

This paper firstly proposed the method of the low speed wire electrical discharge turning (LS-WEDT) method to fabricate micro parts. Firstly, the rotating apparatus submerged in working fluid is designed and manufactured to enable the low speed wire electrical discharge machine to generate cylindrical geometries. Besides, material removal rate, surface roughness and machining precision of micro shafts manufactured by the LS-WEDT are respectively investigated. Experimental results display that the micro-rod of 70μm in diameter and 1000μm in length can be successfully fabricated with high machining precision and good surface quality of the micro shaft.
