摘要
Among the nontraditional machining process, electrical discharge machining (EDM) is one of the significant processes for machining complicated and complex shapes. An experimental investigation was made with the help of electrical discharge machine on Inconel 718 using brass electrode tool to study the vibration behavior in the titanium carbide nanoparticles mixed dielectric fluid environment. Titanium carbide nanoparticles mixed with dielectric fluid possess a high strength, have good electrical and thermal properties and require lesser machining time than pure dielectric fluid. In this experiment, the central composite second order rotatable design and response surface methodology were used to develop an experimental model. Based on the developed models, analyses on machining characteristics of titanium carbide nanoparticles mixed EDM have been carried out. The current, pulse on time and pulse off time were considered as input process parameters and the output process parameters such as material removal rate and surface roughness were evaluated. Analysis of variance has been conducted to check the ability of the developed regression models. The investigations revealed that best surface finish could be obtained by setting the EDM machine parameters at low current and short pulse on time.
