Machining performance of nodular iron with coated cutting tools

Published Online:pp 30-45

This paper overviews typical machining characteristics obtained in the turning of the GJS-500-7 nodular iron when using cutting tools coated with single TiAlN and multiple TiC/Ti(C,N) /Al2O3/TiN layers and P20 uncoated competitors. The experimental data presented include the cutting forces, the average interface temperature, friction and contact length, as well as extended analysis of surface finish. It is concluded based on many machinability factors that multilayer coated tools outperform the other tools applied.
