“…This is analogous to the material effect observed in abrasive wear studies in metal cutting. Hence, the relative hardness and size of abrasive particles (i.e., micro-size carbides and nitrides in steels and superalloys) with respect to the tool material should be considered as a key machinability [33,34] and grindability indicator [32,35]. The behaviour of non-metallic oxide inclusions is rather complex.…”

“…Among them, the smooth wear is characterized by a smooth worn surface without obvious scratches and grooves. This wear mode is prone to appear for the workpiece materials with low hardness and high activity, just like titanium alloys, which is generally related to the atomic dissolution/diffusion between the tool and workpiece material [22]. For carbide tools with coating, the wear always starts with coating flaking and smooth wear during the cutting of Ti alloys.…”

Machining, especially dry machining of titanium alloys, has been one of the most significant challenges for carbide cutting tools. In this study, aluminum-rich AlTiN coating, as well as TiAlSiN nanocomposite coating, were successfully employed for dry milling of Ti-6Al-4V alloy with high efficiency and long tool life. At the cutting speeds of 150 m/min and 200 m/ min, the tool life of the TiAlSiN-coated tool exceeds that of AlTiN-coated tool by 32 and 66%, respectively. The wear modes for both coated tools include the uniform flank wear, smooth wear, chipping, coating and substrate flaking, crater and notch wear, and the wear mechanisms include adhesion, diffusion, oxidation and crack. Among them, the wear mechanism is dominated by the adhesion and oxidation wear. As compared with AlTiN coating, TiAlSiN coating exhibits better mechanical properties and oxidation resistance, which contribute to a better cutting performance, fewer thermal cracks and smaller and uniform workpiece chips during the dry milling of Ti-6Al-4V alloy.

“…Further, the presence of hard/ abrasive carbides in the microstructure significantly impacts tool wear. 17 Hoier et al 18,19 investigated tool wear in Alloy 718 machining and identified that carbides like MC and M7C3 abrade the tool at elevated temperatures. Microscopic analysis revealed abrasive wear-induced flat-worn surfaces featuring grooves aligned with the sliding directions of both chips and workpieces.…”

This study investigated the wear prediction of BTA drills for laminated Inconel 625 deposited metal and FeCr alloy materials using 3D finite element modelling. High interface temperature owing to increased cutting speed enhances the abrasive wear mechanism of Inconel 625, while FeCr alloy exhibits a predominantly adhesive wear mechanism. The interface temperature and normal pressure required as inputs for tool-wear prediction were obtained using response surface methodology (RSM), which was developed by combining the central composite design (CCD) with finite element method simulation. This approach significantly improved the computational efficiency and provides accurate predictions with the calibrated friction model. A modified Usui wear model was established considering the sensitivity of temperature to wear rate for Inconel 625. A significant improvement in prediction accuracy was observed compared with the original Usui equation. The proposed tool-wear prediction model was validated through experimental tests. The maximum predicted flank wear width deviations for the outer and intermediate edges of BTA drill were 2% and 7%, respectively. The results demonstrate the effectiveness of the proposed BTA drill wear-prediction approach for laminated materials with different wear characteristics, providing theoretical guidance for cutting-parameter optimisation and tool-replacement strategies.
