“…For environmental protection and resource efficiency, minimum quantity lubrication (MQL) and biolubricants offer a high potential [8][9][10]. In the case of biolubricants under MQL conditions, Safie et al investigated rice bran oil, neem oil, and castor oil and showed some benefits with castor oil [11]. Compared with mineral cutting fluid, vegetable-oil-based emulsion can feature better properties for the turning of AISI 1050 steel by improving machinability as shown by Carvalho et al [12].…”

An understanding of the proper application of metalworking fluids (MWFs) is necessary for their implementation in efficient production processes. In addition, the knowledge of the process-related aspect of chip transport and the macroscopic cooling effect, the characteristics and properties of lubricant film formation, and the cooling conditions in the secondary shear zone on the chip surface, i.e., in the direct vicinity of the material separation, represent a combined fundamental scientific issue within production engineering. The aim is to transfer methods from the field of tribology of machine elements, which have already led to a considerable gain in knowledge in this discipline, to machining and to couple them with already established approaches to machining. In the case of roller bearings, the contact pressure is in the range as the pressure in the contact zone between the cutting insert and chip. Due to this, established methods might be transferred to the cutting process. In addition to classical pin-on-plate and pin-on-ring friction investigations, film thickness measurements were carried out and compared to machining tests. The coefficient of friction determined in the planing test rig is 0.48 for dry cutting, while it is 0.47 for wet cutting. These two values are much larger than the CoF with MWFs measured on the two tribometers. It is shown that the boundary friction of MWF especially influences the machining process. Thus, additives in MWF might have a high significance in machining.

The term “sustainable manufacturing” refers to both the production of sustainable products as well as the production of all products in a way that is environmentally friendly, energy efficient, and safe for workers, communities, and customers. In the context of sustainable machining, the application of non-polluting cutting fluids plays an important role in improving the machining properties. However, the machining of gun metal is difficult because of generation of friction and cutting temperature at main cutting zone. Hence, it’s very difficult to obtain the product made from gun metal at specific size and desired tolerances. A primary goal of this paper is to establish an accurate method for measuring the machining responses of gun metal with the aid of sustainable cooling strategies. The machining has been carried out using the TiAlN coated tungsten carbide inserts and the machining performance in terms of temperature, surface quality, tool wear, chip condition and power consumed is measured under distinct speed-feed and cutting regimes. The cutting parameters selected were the speed of 75 and 115 m/min and the feed rate of 0.05–0.15 mm/rev. The utilization of cryogenic carbon dioxide (cryo) results in a maximum temperature reduction, which in turn leads to an improvement in the surface quality. In comparison to other cutting settings, the SEM pictures of chip indicate a relatively low level of serration; nonetheless, there is not a significant difference between MQL and flood circumstances. Moreover, cryo-CO2 consumed less power to machine the work material.
