MACHINING PROCESSES OF SILICON CARBIDE : A REVIEW

Silicon Carbide (SiC) is an inorganic material having mechanical, thermal, electrical and chemical properties, due to which it is widely used in developed industries. However, the beneficial properties of SiC ceramic such as high hardness, high strength, wear resistance, extreme brittleness and chemical stability make SiC machining difficult and costly through conventional and non-conventional machining methods. Hence, in present study an overview of previous work on SiC ceramic is carried out. Many researchers attempted various methods for machining of SiC ceramic from which electro discharge machining process, laser machining process, grinding process and diamond turning machining process is the most applied methods. The theoretical, experimental and simulation studies are considered for obtaining significant results. The researchers mainly focused on Material removal rate, surface roughness, surface finish and tool wear rate.
