Investigation of Cutting Performance of Nano/Layered Hard Coatings in Face Milling of AISI D2 Steel

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 AISI D2 face-milling was evaluated work. Single-layer hard-coated uncoated were used to compare testing. All cutting-speeds nano-layer tool presented longer cutting-length than TiAlN TiN ones tool. Notch an overriding mechanism, followed by build-up edge formation all cutting-tools. Using AlTiN / hard-coating, cutting-force values lowered experiments.
