Abstract

Wire electrical discharge machining (WEDM) is a precision machining method for cutting electrically conductive materials. It is an unconventional machining process that produces precision parts. The objective of the study is to investigate the impact of wire electrical discharge machining (WEDM) process parameters on the machining of stainless steel (SS304). These parameters are optimized to increase productivity by maximizing material removal rate (MRR). The factors that can affect the characteristics of machining or cutting in wire cut EDM process are wire tension (N), pulse time-off (μs), current (A), and voltage (V). The effect of these inputs parameters on the MRR response is analyzed and optimized using the response surface methodology (RSM) in the design of experiment (DOE) statistical method. The results from the RSM showed that the current (A) parameter had the most significant effect on the material removal rate.
