A Research Review On The Machining Of Metal Metrix Composite (Mmc) Materials Using Ultrasonic Assisted Electric Discharge Machining (Uaedm)

Abstract

Advanced materials known as metal matrix composites (MMCs) have excellent wear resistance, low thermal expansion coefficient, high specific strength, and increased hardness. They are also lightweight. Reinforcement is hard to manufacture with conventional methods, which has slowed down MMC progress. Since the reinforcement is abrasive, using conventional technology to process MMCs results in significant tool wear. The most dependable nonconventional machining method for MMCs is hybrid electric discharge machining, which has great potential. It demonstrates increased proficiency in precisely machining intricate forms. An improved EDM method that reduces the limitations of the EDM process is Ultrasonic Assisted Electric Discharge Machining (UAEDM), a hybrid EDM process combining EDM and ultrasonic machining techniques. A lot of materials, including ceramic, titanium alloy, and aluminium alloy, are machined using UAEDM for Metal Matrix Composites (MMC). The machining characteristics of the UAEDM process for MMC materials are represented in this review study. A review has been conducted on the effects of various MMC, such as Nickel base alloy, Titanium base alloy, Ceramics, Alumina base alloy, etc., and Tool Material, such as Alumina, Copper, Brass, etc., on Output Parameters, such as Material Removal Rate, Tool/Electrode Wear Rate, Surface Roughness, Aspect Ratio, Crack Propagation, etc. Future research has been identified to enhance productivity and machinability by strengthening the UAEDM process, based on a survey of several literature sources.
