Evolutionary Techniques in Optimization of Machining Parameters on Hybrid Metal Matrix Composites—A Review

Metal Matrix Composites (MMC) are finding wide application across a range of manufacturing areas such as automotive, defense, and aerospace sectors due to their improved strength-to-weight ratio, superior quality, light weight, high strength, and an appreciable amount of hardness when combined with suitable reinforcement material. Non-Conventional machining has gained popularity in recent years to be the first choice for machining Hybrid MMCs. Faster tool wear, poor machinability, and inefficient production process in traditional machining have led to this shift towards unconventional machining methods. Today in this rapidly growing and aggressive industrial environment, manufacturer objectives are to bring out superior products with minimum cost and in a limited frame of time. Optimization of non-conventional machining process parameters such as pulse off time, peak current, pulse on time, and servo voltage will help us to achieve this ultimate goal. This current paper reviews the research on various hybrid MMCs that took the advantage of evolutionary optimization techniques to optimize non-conventional machining process variables and their impact on machining performance.
