Investigating Part Quality and Morphology in Machining Aluminium 7075 Alloy with Nano-Graphene Water-Based Cutting Fluid
摘要
In metal machining, cutting fluid plays a crucial role in boosting production efficiency. Unlike traditional flood lubrication, Minimum Quantity Lubrication (MQL) has become a favored method for various processes, including metal cutting, due to its ability to reduce lubricant consumption and lessen environmental impact. Moreover, nano-cutting fluid, which combines conventional cutting fluid with nanoparticles, acts as a uniform nanoparticle suspension within the fluid. It has demonstrated potential in enhancing the efficiency of the cutting process. This study examined the impact of nano-graphene cutting fluid on machining aluminium 7075 (AA7075) alloy under various machining conditions. This study emphasizes part quality and morphological analysis. The results indicate that adding nano-graphene to the cutting fluid enhances its wetting and cooling properties, significantly improving cutting performance and part quality. Morphological analysis with a Scanning Electron Microscope and an Energy Dispersive X-Ray analyzer supports these findings. The affordable nano-graphene cutting fluid offers a promising method for optimizing the machining of AA7075 alloys, delivering better performance and quality.
