Zusammenfassung:The objective of this study is to present a novel nanofluid/minimum quantity lubrication (MQL) technology for a 7075-T6 aluminum alloy micro-drilling. This technology will enhance the life of the tool for the precision machining. Exploration of nanofluid/MQL-related parameters will affect the effectiveness of distance of nozzle, the nanodiamond weight percent concentration, and the MQL air volume process using the Taguchi robust design method. Additionally, using the Taguchi robust process design also yields the best results when compared with the other micro-drilling characteristics of the dry and MQL methods. Experimental results show that the use of nanofluid/MQL (2 wt%) can effectively reduce the micro-drilling force and micro-drilling torque force as well as the micro-drilling tool for micro-drilling burr wear. Furthermore, there is a significant improvement in the quality of its micro-drilling when the temperature of the drilling process can be significantly decreased.
