ABSTRACT

In WEDM material of wire is of great importance because it affects material removal rate as well as surface finish of work piece. In this experimental work, two different wires i.e., cryogenically treated zinc coated diffused brass wire and plain brass wire has been used as cutting tool. In this study AISI D3 die steel has been taken work piece. AISI D3 tool steel is a high-carbon, high chromium, oil-hardening tool steel. Typical applications for D3 tool steel include blanking, stamping, and cold forming dies and punches for long runs; lamination dies, bending, forming, and seaming rolls, cold trimmer. The input process parameters considered in this research work are pulse width, time between two pulses, wire mechanical tension and wire feed rate. Taguchi’s L9 orthogonal array has been used for design of experiments. The process performance is measured in terms of surface roughness (SR). After performing the experiment result of both wires have been compared. It is found that the cryogenically treated zinc coated diffused brass wire gives good surface finish as compare to cryogenically treated plain brass wire.
