| Abstract | ||
| This work summarizes the effect of edge round preparation for three types of ceramic cutting tool materials (Al2O3/ZrO2, Al2O3/ TiC, Si3N4/Y2O3) upon cutting forces and stress distribution on the cutting tool in orthogonal cutting as determined with Finite Element Method simulations. The results obtained from this study provide a fundamental understanding of the process mechanics for cutting with realistic cutting tool edges and may assist in the optimization of tool edge design. These results compare with other previously published papers and showed a good agreement. It is also proved, that for every cutting condition and tool material, there is an optimum geometry. The material of ceramic cutting tools proved, that it has been good in performance comparing with other previously published papers. | ||
