Abstract
The growing benefits of ceramic composites in their usages in automotive, Bio medical implants, nuclear, and aircraft industries make them the most sought-after significant material. However, cutting these composites with traditional machining is very challenging. The non-traditional machining process like electric discharge machining (EDM) are crucial to machine them. Wire EDM is equipped to machine any kind of material, regardless of how it naturally behaves. Using a coated copper electrode, the current work focusses on investigation of the effects of Wire EDM parameters on Si3N4-TiN ceramic composite. The major machining parameters are servo voltage, short pulse on time, and pulse on time, which were varied over five levels, whereas cutting rate and width of cut are considered as the machining performance characteristics. Using Response Surface Methodology (RSM) that is based on Design of Experiments (DOE) the distinctive characteristics of the WEDM process are investigated. Empirical models have been created for cutting rate and kerf width. According to the findings, the servo voltage is the second most important component, after the pulse-on time.
