Control of thermal conditions in the grinding zone is possible through effective delivery of substances with cooling, lubricating and antiadhesive properties during the machining process. In addition to the benefits of coolants, however, a number of economic and ecological problems arise, which include the costs of purchase, use and maintenance as well as the environmental impact of its disposal. These negative aspects of the use of cooling and lubricating liquids have contributed to the modern trend of minimizing their output in machining processes, including grinding. This article presents comprehensive characteristics of knowledge in the field of liquids, gases and solids with cooling, lubricating and antiadhesive properties. The author’s original classification of cooling and lubricating agents by their physical state was proposed and a complete list of known modern environmentally friendly methods of cooling and lubrication of the grinding zone was presented. In order to highlight their beneficial features, the background of conventional methods of delivery coolants, lubricants and antiadhesives to the grinding zone used for years were also characterised. A comprehensive list of all known methods of cooling and lubrication of the grinding zone classified according to the physical state of the delivered medium with a clear separation of hybrid methods consisting in simultaneous delivery of many cooling and lubricating agents was described in the summary. The article concludes with the characteristics of directions of further development in the field of cooling and lubrication of the grinding zone.

“…They have claimed to have a better surface topography and tool wear behavior in those improved conditions. For another superalloy, Wojtewicz et al [36] improved the performance of the minimum quantity cooling by adding MoS 2 and graphite during the machining of Inconel. For the same group of materials, the performance of MQL was reported to improve when using hBN nanoparticles [37].…”

Environmental protection is the major concern of any form of manufacturing industry today. As focus has shifted towards sustainable cooling strategies, minimum quantity lubrication (MQL) has proven its usefulness. The current survey intends to make the MQL strategy more effective while improving its performance. A Ranque–Hilsch vortex tube (RHVT) was implemented into the MQL process in order to enhance the performance of the manufacturing process. The RHVT is a device that allows for separating the hot and cold air within the compressed air flows that come tangentially into the vortex chamber through the inlet nozzles. Turning tests with a unique combination of cooling technique were performed on titanium (Grade 2), where the effectiveness of the RHVT was evaluated. The surface quality measurements, forces values, and tool wear were carefully investigated. A combination of analysis of variance (ANOVA) and evolutionary techniques (particle swarm optimization (PSO), bacteria foraging optimization (BFO), and teaching learning-based optimization (TLBO)) was brought into use in order to analyze the influence of the process parameters. In the end, an appropriate correlation between PSO, BFO, and TLBO was investigated. It was shown that RHVT improved the results by nearly 15% for all of the responses, while the TLBO technique was found to be the best optimization technique, with an average time of 1.09 s and a success rate of 90%.

“…Ordinarily, the main disadvantage of the precision injection mold is that the mold service life was limited by the characteristics of injection mold materials. Therefore, some reinforcing additives, such as wollastonite, molybdenum disul de [39][40][41], silica sand, glass sphere, zirconia [42][43][44], silicon nitride [45][46][47], or silica sand were recommended for adding to the injection mold. In this study, the injection mold was employed in wax injection molding for manufacturing precision wax patterns.…”

Injection molding is a cost-effective to manufacture molded products by injection molding machine. A precision part with microstructures can be fabricated effectively through a precision mold. In this study, a cost-effective method for rapid manufacturing a precision component and a precision injection mold with microstructures by integrating additive manufacturing, rapid tooling, and computer numerical control milling. It was found that of the dimensional accuracy of a precision component in the length, width, and height can be controlled at approximately 30 µm. Injection molding was performed using an injection mold with microstructures with a microstructure of 950 µm and the dimensional accuracy of a molded part in the length, width, and microstructure can be controlled at approximately 60 µm, 50 µm, and 10 µm, respectively. The remarkable findings of this study can be used for the fabrication of molds or dies efficiently and economically for trial production in the mold industry since the quality of the precision component and the precision mold can meet the standards of the general industry.
