摘要

A comparable amount of overall production expense goes into the traditional cooling lubricating system. Dry lubrication or minimal quantity lubrication (MQL) can replace conventional cooling lubricants to lower machining costs. If solely the economic and ecological aspects are taken into consideration, dry machining may be superior to the wet process. However, dry machining has some restrictions, such as when machining sticky materials, such as pure aluminum. The material adheres to the cutting tool’s face with ease when it is rotated. As a result, the machining rate decreases, the cutting temperature rises, and the rate of tool wear increases. This reduces the tool’s lifespan. Furthermore, it has been discovered that the temperature and wear rate characteristics during the machining process are significantly influenced by the selection base fluid used in minimum quantity cooling lubrication (MQCL) machining techniques. Additionally, when utilizing hybrid MQL techniques, selecting the appropriate process parameters such as feed rate, depth of cut, cutting speed, and tool nose radius will provide good surface roughness. This review offers a comprehensive understanding of the effects of different cutting fluids, and process variables employed to reduce the temperature and wear rate characteristics at the tool–chip–workpiece interface. And also, it provides various investigation models utilized for predicting the process and response parameters values. Moreover, a comparative analysis is provided to demonstrate the effectiveness of various MQCL-assisted machining process in various hard turning materials. Finally, future directions are given to get over the current drawbacks of different approaches in the MQCL-aided machining process and reduce the temperature at which the tool–chip–workpiece contact is formed and the wear rate.
