“Improvement of surface finish of ceramics”- A review

Surface finish is one of the most critical quality measures in many ceramics industries. Global competition and enhanced customer awareness has increased the need for better surface characteristics like surface finish both for function and aesthetics. Nowadays grinding is one of the most popular methods of machining hard materials. The most frequent reason for grinding is that the part material is too hard to be machined economically by a non-abrasive process. Ceramics among the hardest of materials can be processed only by grinding. There are parameters such as feed rate, depth of cut that are known to have a large impact on the surface finish. The significance of the grinding parameters on the selected responses can be evaluated using analysis of variance. This paper provides valuable insights into the surface finish of ceramics.
