| Summary: | Silicon Carbide (SiC) is a type of ceramic that belongs to the class of hard and brittle
material. Machining of ceramic materials can result in surface alterations including rough surface,
cracks, subsurface damage and residual stresses. Efficient milling of high performance ceramic
involves the selection of appropriate operating parameters to maximize the material removal rate
(MRR) while maintaining the low surface finish and limiting surface damage. SiC being a ceramic
material, its machining poses a real problem due to its low fracture toughness, making it very
sensitive to crack. The paper discusses milling of silicon carbide using diamond coated end mill
under different machining conditions in order to determine the surface roughness parameter, Rt after
the machining processes and to establish a relationship between the machining parameters and
response variables. Based on the surface roughness carried out the lowest Rt obtained is 0.46 μm. |
