Abstract

Wire electrical discharge machining (WEDM) is a non-traditional machining process that is widely used in the machining of conductive materials. This paper presents the investigation on surface roughness and metal removal rate of stainless steel using the wire-cut EDM process. Process input parameters wire feed (WF), wire tension (WT), servo voltage (SV), pulse on time (TON) and pulse off time (Tuff), and the output parameters surface roughness and metal removal rate. The work piece material was used stainless steel 310 L, zinc-coated brass wire of 0.25mm diameter used as a tool and distilled water is used as dielectric fluid. ANOVA used to measure and evaluate the relative importance of different factors. Experiments are designed and analyzed using the factorial design approach. The experimental results revealed that the most important machining parameter of the pulse of time has the most influence on the metal removal rate and the surface roughness. The maximum best metal removal rate is (0.052277 g/min). When the values are somewhat medium range, they are the best and the wire does not break at this range. Wire feed (7m/min), wire tension (7 kef), servo voltage (30 V), TON (30 sic), Tuff (30 sic). The expected values and measured values are well-matched as observed by additional confirmation experiments.
