Abstract: Advanced ceramics are increasingly utilised in various engineering applications such as aerospace, marine, automobile, etc. Grinding is commonly used for producing parts of high precision and high surface quality from advanced ceramics. But, there are only a few investigations on the effects of process parameters on surface roughness of advanced ceramics in surface grinding. The objective of this work is to model and optimise surface roughness of silicon carbide (SiC) advanced ceramic material during surface grinding. In the present work, a new for surface roughness in surface grinding of SiC advanced ceramic material is proposed. Effectiveness of this model is proved by comparison of the experimental results with the predicted results. Finally, optimisation of surface roughness is done considering machining parameters such as table feed rate, depth of cut and wheel speed using response surface methodology (RSM) in Design Expert software.
