Research on durability of AlCrN coated tungsten carbide (WC-Co) cutters during oakwood milling

Abstract

The article presents research results on resistance to wear of tungsten carbide(WC-Co)cutterscoated and not coated with AlCrN coating and intended to mill oak-wood. The specimens of oakwood milled in three different climbmilling modes were tested. The cutters' resistance to wear was assessed using the optical method, when radius of the cutting edge was measured. The edge radius and roughness of processed surface were measured in the cutting length up to 9050 m. The received results disclosed that AlCrN-coated cutters are more resistant to wear.
