“…Further, Looney et al[51] had examined the effects of cutting speed on tool wear, cutting forces and surface finish while machining of SiC reinforced Al matrix MMC. They concluded that CBN tool exhibited the best performance over silicon nitride tool whereas carbide tools worn out significantly at a rapid rate.Drilling:In the experimental work carried out by Coelho et al[52,53], they presented results of machinability tests performed in conventional speed drilling and high-speed drilling. These tests were carried out with the PCD tool on Al-based MMC with 15% SiC reinforcement.…”

Intrinsically smart, metal matrix composites (MMCs) are lightweight and highperformance materials having ever expanding industrial applications. The structural and the functional properties of these materials can be altered as per the industrial demands.The process technologies indulged in fabrication and machining of these materials attract the researchers and industrial community. Hybrid Electric discharge machining is a promising and the most reliable non-conventional machining process for MMCs. It exhibits higher competence for machining complex shapes with greater accuracy. This paper presents an up-to-date review of progress and benefits of different routes for fabrication and machining of composites. It reports certain practical analysis and research findings including various issues on fabrication and machining of MMCs. It is concluded that polycrystalline tools and diamond coated tools are best suitable for various conventional machining operations. High speed, small depth of cut and low feed rate are a key to better finish. In addition, hybrid EDM has proved to be an active research area in critical as well as non-conventional machining since last few years. This paper incorporates year wise research work done in fabrication, conventional machining, nonconventional machining and hybrid machining of MMCs. Conclusions and future scope are addressed in the last section of the paper.

“…Thermal degradation occurs due to the presence of cobalt in the interstitial regions and the adherence of cobalt to the diamond crystals. Specifically, cobalt is known to cause an undesired catalyzed phase transformation in diamond (converting it to carbon monoxide, carbon dioxide, or graphite) with increasing temperature [37][38][39][40]. As temperature increases, graphitization of the diamond in the presence of cobalt becomes a dominant effect.…”

This chapter first discusses the challenges with the tool material selection for machining of high-silicon aluminum-matrix composites. It is shown that the combination of a soft easy-to-adhere Al-matrix and highly abrasive particles limits the use of cemented carbide tools due to high rate of adhesion and abrasion wear. The issue becomes intolerable in high-speed machining applications. As a result, polycrystalline diamond (PCD) is slowly becoming a material of choice for such applications. The chapter presents the major research advances in PCD as a tool material. The wear mechanism of PCD is discussed at macro-and micro levels. A discussion on the need and a report on the progress in the development of thermal stable grades of PCD conclude the chapter.

“…Industriediamanten sind meist klein und werden meist in große Sägeblätter, Bohrköpfe oder als Pulver in Poliermassen eingearbeitet (Coelho et al 1995), Spezialanwendungen sind Versuche unter hohem Druck oder sehr stabile Beschichtungen (Harris 1999;Nusinovich 2004). (Sirtl und Reuschel 1964), auf die das beim Zerfall gebildete Silicium aufwächst.…”
