Project Abstract

Due to the desired material properties in the aerospace sector, Ti-6Al-4V and Inconel 718 superalloys are commonly utilized. However, due to properties such as low thermal conductivity, high chemical interaction tendency, and resistance to wear, these materials pose significant challenges in machining processes, often characterized as "difficult-to-cut" materials. This project aims to experimentally investigate the combined use of Ultrasonic Vibration Assisted Machining (UVAM) and Nanofluid Minimum Quantity Lubrication (NMQL) techniques to improve the machining performance of Ti-6Al-4V and Inconel 718 superalloys, which are difficult-to-cut materials commonly employed in the aerospace sector. Within this scope, various cooling methods including conventional machining with UVAM, dry cutting with NMMY, conventional cutting fluid, and pure-MQL are comparatively studied, and the obtained results are analyzed. Three different nanofluids, namely Al2O3, CuO, and Al2O3-CuO (hybrid), are prepared and utilized in experiments when employing the NMMY technique. Machining performance criteria are determined as cutting forces, surface roughness, surface topography, surface texture, geometric accuracy, tool wear, and subsurface plastic deformation measurements. According to the results obtained, it is found that when UVAM and NMMY techniques are used together, the combination yields the highest efficiency in machining performance compared to other methods for both Ti-6Al-4V and Inconel 718 materials. Furthermore, among the NMMY conditions, the hybrid (Al2O3-CuO) usage provides the best results, followed generally by CuO and then Al2O3 added nanofluids. Based on the information and data obtained in this project, it is clearly evident that the yet underutilized UVAM and NMMY techniques, both separately and together, can be applied more efficiently in milling Ti-6Al-4V and Inconel 718 materials compared to traditional methods. This is anticipated to contribute to the aerospace manufacturing sector.
