This work presents an extension of a previous investigation [1] conducted on gaining an understanding of the critical tribological issues encountered in the machining of compacted graphite iron (CGI) using different cutting tool materials. As part of this study, wear tests were conducted on flat-faced coated and uncoated carbide tools and coated and uncoated cermet tools. The machining tests were conducted under dry condition. Performance assessment of the cutting tools was made using a comparative analysis of the measured cutting forces and post machining scanning electron microscopy (SEM) of used tools. The results reveal the interaction of selected cutting conditions and tool substrate material and coatings on the tribological performance and wear behavior of tools during CGI machining.
