Wear of three-treads uncoated and coated integral hob milling tools

Tribological Processes in the gear cutting of cylindrical gears on cutting elements of hob milling tools develop under specific conditions. The particular requirements under which the contacts between the hob milling tools and the workpiece material are made, make it difficult to become familiar with the tribological processes on them so that today there is more knowledge about their consequences on the machined surface of the teeth and the cutting elements of the hob milling tool, and less about their nature. In this paper, based on the experimental investigations, the wear analysis of three-treads uncoated and coated integral hob milling tools in the gear cutting of cylindrical gears is given.
