Abstract
In the present study, the net shape manufacturing of alumina ceramics was carried out using computer numerically controlled (CNC) machining of differently processed alumina green bodies using different tool materials and geometries. In case of a carbide‐coated tool, severe wear was observed; on the contrary, a diamond‐coated tool was used successfully. The profile of the as‐machined surface was found to be smooth using diamond‐coated flat tool. Near net shape alumina was demonstrated using CNC green machining from optimized machining conditions. Optical micrograph and the surface roughness of the as‐machined samples showed good surface finish for the green bodies with higher binder content.
