Sažetak
The influence of hard coatings and machining parameters, in particular cutting speed, feed per tooth and depth of cut on specific cutting energy, productivity and surface quality in milling of hardened cold work tool steel, were investigated in this paper. Taguchi's design of experiments was employed for planning of experiments using L27 orthogonal array. Optimal setting of machining parameters for multi-objective characteristics was determined using grey relational analysis. The principal component analysis was used to define the corresponding weight factors of each quality characteristics under optimization. Analysis of variance was conducted and it was revealed that feed per tooth is the most significant parameter affecting quality characteristics. Finally, results of confirmation test with the optimal machining parameters settings have shown that the proposed model improves overall performance of hard milling process.
