Ceramic Cutting Tool

This paper deals with the study of the experimental observations of the performance of the two types of advanced ceramic cutting tools (Zirconia toughened alumina ceramic cutting tool and Ti[C,N] mixed alumina ceramic cutting tool) by machining them on hardened steel having different hardness numbers. The generalized relationship for the surface roughness, tool life and wear produced on the work piece for particular ranges of cutting speeds are found out by conducting the desired test.

The performance of advanced ceramic cutting tools is also compared with other cutting tools (Carbide, Cermets, etc) and the tool life vs cutting speeds as well as hardness to temperature relations are plotted. The effect of different cutting edge profiles on the performance of the ceramic cutting tools is also seen. The cost analysis of ceramic cutting tools and their advantages and drawbacks are also mentioned.
