Machinability of Al-SiC metal matrix composites using WC, PCD and MCD inserts

Abstract: SUMMARY:The aim of this work is the study of the machinability of aluminium-silicon carbide Metal Matrix Composites (MMC) in turning operations. The cutting tools used were hard metal (WC) with and without coating, different grades and geometries of Poly-Crystalline Diamond (PCD) and Mono-Crystalline Diamond (MCD). The work piece material was AMC225xe, composed of aluminium-copper alloy AA 2124 and 25% wt of SiC, being the size of the SiC particles around 3 μm. Experiments were conducted at various cutting spe… Show more

“…It is an ongoing debate in the scientific world whether sintered carbide cutting tools are suitable for machining MMCs. Many researchers have argued that carbide-coated cutting tools are not suitable for machining MMCs [52,53]. In the machining of MMCs, the use of carbide tools is beneficial after certain conditions are met [33,54].…”
