Green manufacturing through sustainable machining process

Metal cutting industry is under increasing pressure as a result of competition, rigid environmental and health regulations and supply chain demand for improved environmental performance. In such a difficult time and circumstances for manufacturers, an advanced manufacturing mode called green manufacturing has become popular as sustainable development strategy in industrial processes. Green manufacturing from the perspective of modern manufacturing strategy has the purpose of reducing and minimizing environmental impact and resource consumption. The fulfillment of these objectives in case of metal cutting would represent a sustainable machining process. Cutting fluids used in machining for a variety of reasons, due to their environmental, social and economical influence has a great impact on sustainability of machining process. More attention focused to the negative effects of the cutting fluids has led to the necessity of finding new solutions. Alternative types of cooling in combination with new materials for making tools are presented as an area for appropriate replacement of the cutting fluids. This paper examines possibilities in metal cutting process improvements considering economic aspects, precisely the cost associated with cutting fluids. The benefits and capabilities of air cooling using vortex tube in milling process in terms of reaching a better surface quality with longer tool life were shown.
