Apply Image Registration to the Wear Measurement and Analysis of Different PVD-Coating Drills
PVD (Physical Vapour Deposition) multilayer coatings were extensively used in cutting tools because of their relatively high wear and corrosion resistance, adhesion strength, hot hardness, and low coefficient of friction. The object of this study is to measure flank wear of dry cutting drills of different PVD coatings, including TiN, TiCN, and TiAlN by using drilling force experiments and machine vision technique incorporated with image registration technique. To obtain an optimal combination of cutting parameters quickly, we applied Taguchi method to plan the drilling experiment. The experimental results show that coating layer is the most important control factor for cutting and the TiAlN-coating drills generate least wear and thus has the longest tool life.
