Machining of Aluminium Metal Matrix Composite: A Review

Machining of metal matrix composite materials is not such easy as compare to monolithic materials like steel, aluminium etc. the reason is highly abrasive nature of reinforcement present in composite which results in damage of work piece and wear development in cutting tool. Cutting tool plays a major role as far as machining is concerned, the objective of machining is to produce a product of desired shape and size with required surface quality and finish. Aluminium based metal matrix composites (AMMC's) finds wide industrial applications such as automobile, aerospace and sports related industries due to their excellent mechanical and physical properties. The cost of machining of a manufactured component amounts 20 % more the value of manufactured product and eighty percent manufactured parts need machining before they are ready to use. In this paper elaborated review has been done regarding problem encountered while machining these materials and especially conventional machining processes like turning and milling has been focused.
