A green machining study to investigate the effect of nano-cutting fluid environments on the machinability of Ti6Al4V titanium alloy

This study primarily focuses on green machining, which refers to the environmentally friendly machining of parts without compromising the environment and human health. Green machining, an innovative approach in the manufacturing industry, aims to reduce the environmental impact and promote sustainable practices throughout the machining process. Green machining involves the utilization of methods such as machining, dry machining, high-performance cutting, hybrid machining, and high-speed cutting, along with environmentally friendly lubrication practices. The objective of this research is to investigate the effects of machining Ti6Al4V alloys, a widely used lightweight metal in the aerospace industry known for its challenging machinability. The study specifically examines cutting force, surface roughness, and tool wear under various cutting parameters and tribological conditions. The use of a new lubrication/cooling method was investigated in order to minimize the effects of traditional cutting fluids used in the machining of difficult materials, which may cause environmental and human health. This way, sustainable green production compatible with the environment has been realized today, where global warming and carbon emissions are rapidly increasing. In addition, it was observed that the factor determining the cutting force was the depth of cut and the feed rate was the most significant factor affecting the surface roughness.
