Investigation of the machining performance of ferritic ductile cast iron in WEDM using response surface methodology

Wire electrical discharge machining (WEDM) technology is a special electrothermal processing method that can precisely production of parts with variable stiffness sharp edges or complex geometric which are difficult to produce by traditional manufacturing methods. It has an important place in sector terms low energy consumption. In this study, the relationship between parameters on surface quality ferritic ductile cast iron (GGG-40) material WEDM process molybdenum wire was investigated Response Surface Methodology (RSM). The aim study determine optimum for low-cost GGG-40 sharp-edged and geometry using method. experimental works, roughness, time were table feedrate, pulse time, space as cutting parameters. surfaces obtained result experiments evaluated Scanning Electron Microscopy (SEM), roughness device. According findings, it been observed increased increasing decreased increasing. Also, understood most factor effecting quality. found depends only federate where they inversely proportional. As RSM analysis, lowest best time/performance condition both process.
