It is well established that titanium based hard coatings (e.g., TiN, TiAlN) can significantly improve the performance and life of cutting tools. More recently, AlCrN coating has been investigated for cutting tool applications in order to improve the tool performance over the titanium-based coatings. The current investigation has been carried out with an aim to compare the performance of TiAlN and AlCrN coatings on a high speed steel milling cutter. A multi-flute cylindrical cutter was coated half of its length with TiAlN coating and the other half with AlCrN coating using cathodic arc deposition technique. The machining test was carried out with the coated cutter in a production environment, where saw teeth were manufactured by milling process. On average, AlCrN coated teeth showed 16% higher flank wear compared to TiAlN coated teeth. Notch wear was also found to be slightly higher in AlCrN coated teeth. The investigation of the worn teeth revealed that abrasive and adhesive wear were predominant in presence of built-up edge (BUE) formation. However, BUE formation was more prominent in AlCrN coated teeth.
