Nowadays, the environmental concern in machining industry is a fact. Because of that, in this article a new cooling-lubrication\ud system which combines CO2 cryogenic and MQL technologies is presented. The aim of this new cooling-lubrication system is to\ud offer an ecological and economic efficient alternative. Two nozzle adapters are proposed with different CO2 outlets. The\ud developed nozzles are Plug & Play and directly applicable to commercial MQL systems. The behaviors of nozzle adapters were\ud simulated by CFD (Computational Fluid Dynamics) and the optimal nozzle adapter was tested by milling Inconel 718 ®. In these\ud milling tests, the tool life was measured and using different main cooling-lubrication techniques: dry, wet, CO2 stand alone, MQL\ud stand alone and CO2+MQL (proposed alternative).Postprint (published version

The continuously growing presence of cyber-physical systems in the industry, especially in the field of processes automation and control, represents the paradigm of the so called fourth industrial revolution, in which the systems are smarter, faster and more optimized by means of artificial intelligence, control systems and sensors networks. The presence of ICT and automation systems guarantees energy and other resources efficiency along the whole value chain of industrial processes. Especially important is the case of the smart sensors, in which a conventional sensor is equipped with interfacing methodologies for signal processing and decision making. In this article the capabilities of using a single board computer as a smart sensor are explored.Postprint (published version
