Abstract: The widespread replacement of metals by the advanced ceramics has been limited by the high manufacturing costs of these materials and the difficulties involved. To meet the increasing demand of advanced ceramics, the current technological constraints should be overcome. One of the main targets in grinding of these materials is increasing the machining efficiency. Utilisation of a segmented grinding wheel can reduce the grinding forces and temperatures and increase the material removal rate. Hence, an especially designed segmented wheel (T-Tool) has been developed in this study. Both theoretical and experimental results illustrate the high performance of the developed grinding wheel. The obtained results show that the application of the T-Tool wheel can increase the G-ratio and decrease the grinding forces considerably. A decrease of up to 35% of grinding forces has been achieved.

Keywords: intermittent grinding; segmented grinding wheels; tool wear; surface roughness; grinding energy; silicon carbide; advanced ceramics; machining efficiency; grinding force; grinding temperature; MRR; material removal rate; surface quality.
