Abstract

Abstract: Issues related to the machinability of hard-to-cut materials such as Titanium and Nickel base superalloy are well studied in past. This article attempts a comparative machinability study of Ti-6Al-4V and Nimonic-90 using conventional and ultrasonic-assisted turning . The ultrasonic-assisted and conventional turning for both the materials are performed under dry and sustainable cutting fluid, i.e., vegetable oil-based cutting fluid, keeping all the process parameters constant. Canola oil is used as vegetable oil. The machinability in terms of power consumption and tool life is analyzed. The ultrasonic-assisted turning under sustainable cutting fluid significantly reduces the power consumption and improves the tool life for both the materials. Comparing the machinability of both the materials, Ti-6Al-4V exhibits higher machinability than Nimonic-90. The sustainable cutting fluid leads to promote sustainability in the machining of Ti-6Al-4V and Nimonic-90.
