“…This kind of layer allows to prevent damages which could occur on the contact surface as proved by many investigations performed in respect of the effectiveness of anti-wear additives [21]. As a result, the reduction of friction causes reduction of temperature which plays a very important role and has great influence on the carbide cutting wedges' properties related to their wear [30].

“…Further, the workpiece subjected to machining can receive an effective lubrication of the contact zone and, consequently, which in extend prolong the tool life [28,29]. More important, the oil mist droplets enable a more effective lubrication for cutting wedge region subjected to machining when comparing with "lubrication" medium used in the MQCL + EP/AW method [30]. The lower cutting wear wedge achieved by applying the active medium containing EP/AW additive when comparing to dry machining can be due supplying water droplets that promote a better lubrication on the cutting zone region as result of the use of phosphate ester.…”

“…Cold air cooling is best during machining as it mitigates the environmental and health issues caused due to use of coolants. Energy consumption increased by 20%, but coolant cost was reduced by 80%, which is an economically good impact [ 174 ]. In the literature, different gases have been exploited as a coolant for sustainable machining of steel, i.e., carbon dioxide (CO 2 ), argon, water vapor, oxygen, and nitrogen, as depicted by Kim et al [ 175 ] and Yamazaki et al [ 176 ] in their investigations.…”

Machining operations are very common for the production of auto parts, i.e., connecting rods, crankshafts, etc. In machining, the use of cutting oil is very necessary, but it leads to higher machining costs and environmental problems. About 17% of the cost of any product is associated with cutting fluid, and about 80% of skin diseases are due to mist and fumes generated by cutting oils. Environmental legislation and operators’ safety demand the minimal use of cutting fluid and proper disposal of used cutting oil. The disposal cost is huge, about two times higher than the machining cost. To improve occupational health and safety and the reduction of product costs, companies are moving towards sustainable manufacturing. Therefore, this review article emphasizes the sustainable machining aspects of steel by employing techniques that require the minimal use of cutting oils, i.e., minimum quantity lubrication, and other efficient techniques like cryogenic cooling, dry cutting, solid lubricants, air/vapor/gas cooling, and cryogenic treatment. Cryogenic treatment on tools and the use of vegetable oils or biodegradable oils instead of mineral oils are used as primary techniques to enhance the overall part quality, which leads to longer tool life with no negative impacts on the environment. To further help the manufacturing community in progressing towards industry 4.0 and obtaining net-zero emissions, in this paper, we present a comprehensive review of the recent, state of the art sustainable techniques used for machining steel materials/components by which the industry can massively improve their product quality and production.

The development of ecological awareness followed by stringent laws on the protection of natural resources and workers direct the manufacturing industry at the development and implementation of alternative methods for cooling and/or lubrication in the machining of metals. The paper investigates the feasibility of using a vortex tube for cooling when turning martensitic stainless steel. Experimental research was conducted to understand the effects of vortex tube cooling on the corrosion resistance of the machined surface and on production costs. It has been determined that the vortex tube cooling has no significant influence on the corrosion resistance and that the tool costs have the most significant influence on the unit production cost. In conclusion, compared to the conventional emulsion cooling in metal cutting, the vortex tube cooling offers a cost-effective solution to the sustainable turning of martensitic stainless steel.
