An Experimental Investigation on Designed and Fabricated WECSM Setup during Micro Slicing of e-glass Fibre Epoxy Composite

The e-glass fibre epoxy composite is a nonconductive ceramic material hence it is difficult to machine by any well known non-conventional machining methods like electrical discharge machining, wire electrical discharge machining etc. This material can be machined with conventional machining but compromise with accuracy, surface texture even not possible to micro slicing etc. Keeping in view, a hybrid machining technique which is combination of both electro chemical machining (ECM) and wire electric discharge machining (WEDM) is used to machine such material. This paper presents the results during machining of e-glass fibre epoxy composite on a designed and fabricated wire electrochemical spark machining (WECSM) setup. The numbers of experiments have been carried out to investigate the effect of different parameters of fabricated WECSM setup on machining performance characteristics such as material removal and spark gap width. Test results revels that the width of micro slicing was very small e.g.127 μm. The practical research analysis and test results present in this paper will provide new guidelines to the manufacturing engineers and upcoming researchers.
