accuracy. Conventional diamond grinding is used to machine SiC, but the process requires high grinding force and for that cutting edges of diamond grinder is easily worn out which makes the process costly and inefficient . In addition, grinding of SiC is difficult because of its low fracture toughness and making it very sensitive for cracking .

Silicon carbide (SiC) is a hard covalently bonded material predominantly produced by the carbothermal reduction of silica (typically using the Acheson process). Depending on the exact reaction conditions the resulting silicon carbide is either a fine powder or a bonded mass that requires crushing and milling to produce a usable feedstock.
