Wear Mechanism of PVD Coated Carbide in High-Speed Turning of Titanium Alloy 
 TA15

The TiAlN and AlTiN coated carbide cutting tools were adopted for high-speed turning of α+β phase titanium alloy Ti-6Al-4V. Both the wear pattern and wear mechanism were investigated in this research. Results show that: MQL condition can greatly prolong the tool life of AlTiN coated carbide tool but has minor influence on improving the tool life of TiAlN carbide tool. AlTiN coated carbide tool was found to be qualified to obtain better cutting performance and longer tool life and is more suitable for processing titanium alloy TC4 compared with TiAlN coated tool under the same cutting parameters. In dry cutting condition, both adhesive and oxidation wear were observed to be the main wear types in these two coated carbide tools. However, in MQL condition, TiAlN coated tool may only suffer adhesive wear while the AlTiN coated carbide tool suffer adhesive, diffusion and oxidation wear.

The wear morphology of rake face and flank face of tool is investigated by turning titanium alloy TC4 with CBN solid tool. It has been observed that the main wear form of rake face and flank face of tool is groove wear. The relation between tool flank wear and cutting speeds, feed rate, and cutting depth obtained from experimental data is given.

Coated Carbide

Tool coatings can improve the machinability performance of difficult-to-cut materials such as titanium alloys. Therefore, in the current work, high-speed milling of Ti6Al4V titanium alloy was carried out to determine the performance of various coated cutting tools. Five types of coated carbide inserts – monolayer TiCN, AlTiN, TiAlN and two layers TiCN + TiN and AlTiN + TiN, which were deposited by physical vapour deposition – were employed in the experiments. Tool wear, cutting force, surface roughness and chip morphology were evaluated and compared for different coated tools. To understand the tool wear modes and mechanisms, detailed scanning electron microscope analysis combined with energy dispersive X-ray of the worn inserts were conducted. Abrasion, adhesion, chipping and mechanical crack on flank face and coating delamination, adhesion and crater wear on rake face were observed during high-speed milling of Ti6Al4V titanium alloy. In terms of tool wear, the lowest value was obtained with TiCN-coated insert. It was also found that at the beginning of the machining pass TiAlN-coated insert and at the end of machining TiCN-coated insert gave the lowest cutting force and surface roughness values. No change in chip morphology was observed with different coated inserts.
