6 - Conventional and unconventional hole making in metal matrix composites

Abstract

Hole making in advanced materials such as metal matrix composites (MMCs) is an essential prerequisite to facilitate their assembly. The secondary processing of MMCs is thus unavoidable in the overall product development cycle. Here we address the issues and challenges in conventional and unconventional hole-making techniques in MMCs. There are a plethora of challenges associated with achieving good-quality cost-effective hole making in MMCs. The conventional (drilling) and unconventional (ultrasonic and electrical discharge machining) techniques of hole making in MMCs are discussed, and the results of previous research are outlined. The chapter provides insight into the fundamental aspects of hole making in MMCs.
