“…2 shows the results of the experiment. In comparison to Priarone et al [30], the wear progression curves display a similar course. The only difference is that experiments made by Priarone et al resulted in shorter tool life, caused by a higher cutting speed of vc = 50 m/min and feed rate of f = 0.1 mm, although the depth of cut with ap = 0.3 mm was significantly lower.…”

“…The only difference is that experiments made by Priarone et al resulted in shorter tool life, caused by a higher cutting speed of vc = 50 m/min and feed rate of f = 0.1 mm, although the depth of cut with ap = 0.3 mm was significantly lower. As explained in [30], the cutting speed plays an essential role during the wear progression of tools. In a short preliminary test for the experiments used for this paper, a cutting speed of vc = 60 m/min with CFL coolant was chosen.…”

Titanium and nickel based alloys are two types of industrially used materials. Especially in aerospace and automotive industry, the intermetallic titanium aluminides tend to replace these prevailing materials. Their density is only a half of nickel based alloys and a high strength at room temperature and hot condition is retained. But the high reaction affinity against tool materials, their low Youngs modulus and low heat conductivity cause difficulties in machining. During the machining process, low heat conductivity leads to high thermal loading of tools and therefore a well-directed cooling strategy is necessary. In this paper an overview about different cooling strategies, such as cryogenic carbon dioxide cooling and minimum quantity lubrication of the titanium aluminide Ti-48Al-2Cr-2Nb is shown. Based on a literature research and the experiments conducted in this investigation, cryogenic cooling is a reliable option for reducing toolwear.

“…In the reference [14], the research aim to evaluate the influence of the lubrication strategy on tool wear, surface quality and environmental impact when milling and turning Ti-48Al-2Cr-2Nb intermetallic alloys. The workpieces were obtained by means of two production processes: vacuum arc re-melting and electron beam melting (EBM).…”

“…It is reported that the costs related to cutting fluids are approximately 16.9% of the total manufacturing costs, compared to tooling costs which represent about 7.5% [3]. This cost can be increased to up to 30% for machining refractory materials such as titanium and nickel-based alloys [4]. It is also estimated that the annual consumption of cutting fluids is about 100 million gallons in the USA [5].…”

This paper presents the development of a new controlled cutting fluid impinging supply system (Cut-list) to deliver an accurate quantity of cutting fluid into machining zones through precisely oriented coherent round nozzles. The performance of the new system was evaluated against a conventional system during the step shoulder milling of Ti-6Al-4V using a water-miscible vegetable oil-based cutting fluid, which was phase 1 in this comprehensive study. The use of Cut-list resulted in a significant reduction up to 42% in cutting fluid consumption as well as reductions in cutting force, tool flank wear, average surface roughness (R a ) and burr height (Gariani et al. in Appl Sci 7(6):560, 2017). This paper details phase 2 of the study which was aimed to investigate the effects of working conditions, nozzle positions/angles and impinging distances on key process measures including cutting forces, workpiece temperature, tool wear, burr formation and average surface roughness of the machined surface. Feed rate showed a significant effect on mean values of cutting force, burr formation and surface roughness, whereas average workpiece temperature and flank wear values are very sensitive to cutting speed. Nozzle position at a 15°angle in the feed direction and 45°/60°against feed direction assisted in minimising workpiece temperature. An impinging distance of 55/75 mm is also necessary to control burr formation, workpiece temperature and average surface roughness. It can be concluded that Cut-list gave promising results compared to conventional flood cooling systems in terms of the evaluated machining outputs. Therefore, the new system can be considered as a feasible, efficient and ecologically beneficial solution, giving less fluid consumption in machining processes.
