A review on minimum quantity lubrication technique Springer

Home Journal of the Brazilian Society of Mechanical Sciences and Engineering Article Review Published: 03 April 2023 A review on minimum quantity According to Lee et al. (2002), who conducted experiments in groove grinding, the compressed air jet is a tool that can be used to reduce clogging because the air impacts the wheel surface and removes a large number of the impurities that adhere to it (see Fig. 2).Consequently, a decrease in the wheel wear rate and an improvement in Improving minimum quantity lubrication in CBN grinding

Performance evaluation of nanofluid-based minimum quantity

The grinding energy obtained during the grinding of Inconel-718 alloy is shown in Fig. 3a. Under dry grinding, the energy consumed was found to be higher than the MQL and flood lubrication conditions (see Fig. 3a). Ogonowski et al. [] reported that dry grinding consumed 15%–50% more energy than flood grinding.The author opinioned Progressing through each major element of a grinding system and then on to machine developments, the reader becomes aware of all aspects of operation and design.
