Study of the machining quality of CMC ceramic composite during high-speed grinding

Abstract

Ceramic matrix composites (CMC) are now an increasingly popular choice of materials used to manufacture critical parts for a variety of engineering applications. Due to the complex heterogeneous structure of CMC and the high hardness of at least one of the components (fiber or matrix)-processing such materials becomes an extremely difficult task. In addition, the heterogeneous structure and brittleness of CMC leads to different material removal mechanisms during machining, resulting in unique surface defects that reduce the quality of the machined surface. This article deals with the issues of ensuring the quality of the machined surface of samples made of SiC/SiC ceramic composite with ceramic matrix, by selecting the characteristics of the grinding tool and cutting modes during high-speed grinding.
