Sažetak
The purpose of this work is to present some guidelines in the sustainable machining processes, using cryogenic conditions and gaining higher performances, lower environmental and health influences, increased safety, etc. The study presents the details about cryogenic fluids and their use in machining processes as an alternative to oil-based emulsions. The details of liquid nitrogen and the ways of their application in the machining processes, known as cryogenic machining process, are given. The research is upgraded with experimental case study on high temperature alloy machining – tungsten, and so presenting an important scientific and sustainability contribution in production processes. Experimental and analytical results are proving that the cryogenic machining technology has a high potential to cut costs and improve competitiveness, by reducing resource consumption and creating less waste and have less of an environmental and social impact, fulfilling the sustainability pillars: economical, social and environmental one, over conventional machining processes.
