Study of the effect of nano-based lubricant in minimum quantity cooling lubrication (MQCL) for machining.
摘要
The main requirement of industries is to produce components at a fast rate of production while maintaining the required quality and cost. Therefore, industries are working on high speed and high rate of feed during machining which leads to high temperatures at the cutting area, which in return causes tool wear and a reduction in surface quality. To overcome this limitation, the cutting fluid in machining operations serves a crucial function of cooling both the Cutting tool and the surface of the workpiece. Additionally, it helps in the removal of chips from the heat-affected area. The excessive use of the cutting fluid and incorrect methods of disposing it can have detrimental effects on the environment and human health, while also increasing the overall cost of the process. The Minimum Quantity Cooling Lubrication (MQCL) strategy is essential in machining due to its utilization of less than 10% of the cutting fluid quantity compared to flood machining. This study provides a comprehensive analysis of the performance of MQCL in comparison to other machining environments, including flood machining and dry processing. The focus is on evaluating the tool performance and surface quality in various machining processes. The paper revealed that machining environments exert a significant impact on wear of tool and quality of surface. As evidenced by numerous studies, the MQCL strategy and nanoparticles based MQCL has consistently demonstrated superior results by minimizing wear of tool compared to alternative cooling and lubrication strategies.
