Impact of Chilled Air Nozzle Types on Surface Integrity in Drilling of Aluminum Alloy 1050

Abstract

Using cutting fluid in the machining process for Aluminum Alloy 1050 is advantageous as it helps mitigate the effects of temperature generated during cutting. It can shorten tool life and impair the quality of machine parts. Despite its benefits, cutting fluids has several disadvantages, such as high expenses, potential environmental harm, and user health risks. This research evaluates the effects of green cutting conditions, particularly nozzle types, on the metallurgical properties of the material. Their impacts on tool wear, X-Ray Diffractometer (XRD) pattern, Full Width at Half Maximum (FWHM), crystallite size, and hardness during the drilling process were investigated. The findings indicate that using chilled air with dual nozzles for cooling and lubrication is highly effective, resulting in less tool wear and a relatively purer crystalline structure of the material compared to other conditions. These results emphasize the importance of controlling cutting conditions, especially nozzle types, to produce high-quality parts with improved metallurgical properties.
