Abstract

Ultrasonic vibration-assisted milling (UAM) process is one of the most recent advancements in the area of milling. In axial UAM process, milling cutter is rotated and simultaneously vibrated in axial direction with high frequency and small amplitude. As observed experimentally, the superposition of axial ultrasonic vibrations in milling operation improved the performance of the process by reducing cutting forces and enhancing surface quality. This study intended to evaluate the machining accuracy of thin-walled structures milled with and without the assistance of ultrasonic vibration. Two different types of thin-walled (with straight and curved geometry) structures were machined by UAM and conventional milling to compare their machining accuracy. Accuracy of machined components was assessed following a reverse engineering technique. Experimental results indicated that the superposition of axial ultrasonic vibrations improved the machining accuracy of the typical milling process of up to 33%.
