Wear data for trials machining brass, titanium grade 2 and Hastelloy in order to characterize wear of micro-tools.

This data article presents data on machining trials that were carried out using 0.5 mm micro-end-mills with different coatings to characterize their wear. The data take the following forms: Tabulated wear measurements, cutting force measurements and graphs of wear against sliding distance. Three materials were machined: titanium grade 2, Hastelloy and Brass (CuZn37). Wear is measured on the flank, rake face and outside edge of the tools. Two coatings were used for each material, with wear data plotted for each material. For further information on experimental methods please refer to "Protocol for Tool Wear Measurement in Micro-milling" (Alhadeff et al., 2018).
