文摘

The e-glass fibre epoxy composite is a nonconductive ceramic material, and 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, etc. However, conventional machining methods cannot be applied to the micro machining range for manufacturing of ultra-precision parts. Keeping in view, travel wire electrochemical spark machining (WECSM), a hybrid machining technique which is a combination of electrochemical machining (ECM) and wire electric discharge machining (WEDM) is used to machine e-glass fibre epoxy composite. This paper presents the results during machining of e-glass fibre epoxy composite on designed and fabricated WECSM. The numbers of experiments have been carried out to investigate the effect of different parameters of developed WECSM on machining performance characteristics such as material removal and spark gap width. Test results revel that the width of micro slice varied from 220 to 223 μm when slicing operation was performed with 200 μm diameter brass wire. The practical research analysis and test results present in this paper will provide new guidelines to the manufacturing engineers and upcoming researchers.KeywordsHybrid machiningWECSMe-glass fibre epoxy compositeMicro slicing
