Description 445-458
The Metal Matrix Composites (MMCs) are being used in many applications, including aerospace, shipbuilding, and
defence industries owing to their high strength to weight ratio. However, the machining of these materials is still
challenging, necessitating advanced machining techniques. The current investigation aimed to analyze the performance of
the grinding-assisted rotary disc-electrochemical discharge machining (GA-RD-ECDM) process during cutting Al-6063
SiCp MMC. Detailed experimentation was performed to study the energy interaction behavior and effect of input process
variables viz. applied voltage, pulse on time, electrolyte concentration, and disc rotation speed on performance measures.
The responses selected were taper, overcut (WOC), and Materials Removal Rate (MRR). The experimentation work was
performed by adopting response surface methodology. Regression models were developed and statistically analyzed through
analysis of variance (ANOVA). Eventually, the GA-RD-ECDM process was optimized using the VIKOR methodology of
multi-criteria decision-making by considering accuracy and productivity simultaneously to obtain minimum taper and WOC
and maximum MRR. The results of ANOVA revealed that input variables were statistically significant. Applied voltage
most significantly affects the performance of the GA-RD-ECDM process performance. The optimal values of input process
variables obtained by VIKOR method were applied voltage = 100 V, pulse-on time = 3 ms, Electrolyte concentration = 18%
wt/vol. and disc rotation speed = 30 rpm. The present work can provide a productive solution for cutting of difficult-to-cut
materials. Thus, in future, the GA-RD-ECDM process can be investigated for other advanced materials (i.e., glass, polymer
composites and ceramics) for fabrication of microchannels for microfluidic applications.
