Cumulative reduction of friction and size effects in micro milling through proper selection of coating thickness of TiAlN coated tool: Experimental and analytical assessments

It has been shown earlier that abrasion-resistant coatings on cutting tool can reduce tool wear and friction in micro milling and other machining processes. However, due to coating, the edge radius of micro end mill increases, and the influences of size effects become significant. Therefore, proper selection of the coating thickness is crucial to reduce friction and size effects together. In this article, thin-film coating of TiAlN of different...
