This paper introduces the surface modi¯cation of Al-6351 alloy by green compact SiC-Cu electrode using electro-discharge coating (EDC) process. A Taguchi L-16 orthogonal array is employed to investigate the process by varying tool parameters like composition and compaction load and electro-discharge machining (EDM) parameters like pulse-on time and peak current. Material deposition rate (MDR), tool wear rate (TWR) and surface roughness (SR) are measured on the coated specimens. An optimum condition is achieved by formulating overall evaluation criteria (OEC), which combines multi-objective task into a single index. The signal-to-noise (S/N) ratio, and the analysis of variance (ANOVA) is employed to investigate the e®ect of relevant process parameters. A con¯rmation test is conducted based on optimal process parameters and experimental results are provided to illustrate the e®ectiveness of this approach. The modi¯ed surface is characterized by optical microscope and X-ray di®raction (XRD) analysis. XRD analysis of the deposited layer con¯rmed the transfer of tool materials to the work surface and formation of inter-metallic phases. The micro-hardness of the resulting composite layer is also measured which is 1.5-3 times more than work material's one and highest layer thickness (LT) of 83.644 m has been successfully achieved.

“…MRR, TWR, radial overcut and Ra. While selecting compact load, current and pulse-on time as the three process parameters, Rahang and Patowari [19] applied Taguchi method to optimize the performance measures, such as TWR, MRR, Ra and edge deviation of an EDM process.Dhuria et al [8] proposed the application of a hybrid Taguchi-entropy weight-based GRA method to optimize MRR and TWR in an ultrasonic machining (USM) process while considering slurry type, tool type, power rating, grit size, tool treatment and workpiece treatment as some of the significant input parameters. Antil et al [1] selected voltage, electrolyte concentration, inter-electrode gap and duty factor as the control parameters in electrochemical discharge drilling of SiC reinforced polymer matrix composite, and later applied Taguchi method along with GRA technique to derive the optimal parametric mix.…”

In order to achieve higher dimensional accuracy along with better surface quality, the conventional machining processes have now-a-days being replaced by nontraditional machining (NTM) processes, because of their ability to generate intricate shape geometries on various advanced engineering materials. In order to exploit their fullest machining potential, it is often recommended to operate those NTM processes at their optimal parametric settings. Several optimization tools and techniques are now available which can be effectively applied to obtain the optimal parametric conditions of those processes. In this paper, Taguchi method and super ranking concept are integrated together to present an efficient optimization technique for simultaneous optimization of three NTM processes, i.e. electro-discharge machining process, wire electro-discharge machining process and electro-chemical discharge drilling process. The derived results are validated with the help of developed regression equations, which show that the proposed approach outperforms the other popular multi-response optimization techniques. Analysis of variance is also performed to identify the most influencing control parameters for the considered NTM processes. The developed response surface plots further help the process engineers in identifying the effects of various NTM process parameters on the calculated sum of squared rank values.

Electrical discharge machining (EDM) is one of the oldest nontraditional machining processes, commonly used in automotive, aerospace and ship building industries for machining metals that have high hardness, strength and to make complicated shapes that cannot be produced by traditional machining techniques. The process is based on the thermoelectric energy between the work piece and an electrode. EDM is slow compared to conventional machining, low material removal rate, high surface roughness, high tool wear and formation of recast layer are the main disadvantages of the process. Tool wear rate, material removal rate and surface quality are important performance measures in electric discharge machining process. Numbers of ways are explored by researchers for improving and optimizing the output responses of EDM process. The paper summarizes the research on die-sinking EDM relating to the improvements in the output response.
