Abstract

Manufacturing sectors strive towards low-toxic, environmentally friendly machining to combat climate change. Due to its low heat conductivity, machining Inconel 718 alloy is a difficult process nowadays. The purpose of this research is to investigate the turning of Inconel 718 alloy under PVD TiAlN inserts, in two distinct environments: Dry and Atomized spray cutting fluid (ASCF). The effect of various machining performances such as Surface roughness (Ra) and Tool life (TL) analysis of Inconel 718 alloy on ecologically friendly machining were investigated. According to the results of the study, the surface roughness of the ASCF machining improved significantly, which was around 40%, when compared to its dry machining. The use of the ASCF significantly decreased the notch and abrasion wear of the tool. This was due to its various features, such as its ability to provide effective lubrication and reduce the cutting temperature.

Keywords- Inconel 718 alloy, Turning, Atomized spray cutting fluid (ASCF), Surface roughness, Tool life.
