The Taguchi method was employed to analyze and optimize titanium carbonitride films on cemented carbide (WC-6% Co-10% TiC-8% TaC) indexable milling cutters with regard to machining conditions. Six variables - the film construction, cutting speed, feed rate, depth of cut, workpiece hardness and milling type - were considered. The results showed that the film construction was the most dominant variable, with a percentage contribution as high as 48.85% to the overall variance of the milling system. Through calculations an optimal film construction was found to be 3 μm TiN + 2 μm TiCN (from the substrate to the top) rather than 5 μm TiCN alone under the conditions specified in this study. The resultant flank wear achieved around 480% and 320% improvement compared with the uncoated and 5 μm TiN coated cutters.
