Özet

In this study, the machinability behaviour of Ti6Al4V alloy was investigated using carbide coated and uncoated inserts at varying cutting speeds, feed rates, and depths of cut. The cutting tool life was determined by analysing chip morphology, insert wear and surface roughness. The study focussed on understanding the physical phenomena during machining and optimising them with experimental and numerical approaches. The novelties of the study are that the performance characteristics of cutting parameters were evaluated using the response surface methodology and were realised in industry. The results show that properly selecting cutting parameters can improve surface quality. The feed rate impacts surface roughness the most, followed by the cutting speed. Helical and ribbon types of chips were obtained in Ti6Al4V alloy turning. The longest wear time was observed for the uncoated tool. The tool life of the uncoated insert improved by approximately 11.12, 11.76 and 18.18% compared to the coated carbide insert at 30, 40, and 50 m min−1 cutting speeds, respectively.
