Abstract :In the die-molding industry, milling steels in a hardened condition is common. Tool wear and cutting-forces occurring during this process must be considered for better surface quality. The cutting performance of nano-layered AlTiN/TiN coated carbide cutting-tools in AISI D2 face-milling was evaluated in this work. Single-layer hard-coated carbide cutting-tools and uncoated cutting-tools were used to compare cutting performance testing. All cutting-speeds nano-layer AlTiN/TiN coated carbide cutting tool presented longer cutting-length than TiAlN and TiN coated ones and uncoated tool. Notch wear is an overriding wear mechanism, followed by build-up edge formation for all cutting-tools. Using a nano-layer AlTiN / TiN hard-coating, cutting-force values were lowered in all experiments.Keywords : Tool wear, Cutting-force, Hardened steel, High-speed machining, nano-layer hard-coatings.
