Improving Slot Milling Performance Using Ultrasonic Assisted Vibration

Abstract

Conventional machining methods face significant challenges when working with hard-to-cut materials, such as advanced ceramics, high-strength alloys, and composites. These challenges include poor surface quality, rapid tool wear, and high cutting forces. This study investigates the enhancement of machining performance through the application of Vibration-Assisted Machining (VAM). By introducing controlled high-frequency vibrations (typically around 26 kHz) to the workpiece side, UVAM aims to improve machinability parameters.The research explores the principles behind UVAM and its impact on reducing cutting forces, improving surface finish, and enhancing debris evacuation. The potential benefits of UVAM, such as improved surface integrity and reduced cutting forces, are discussed. Experimental results demonstrate a significant reduction in cutting forces, surface roughness, and cutting temperature, as well as an extension of tool life. These improvements highlight the efficacy of VAM in machining hard-to-cut materials.The study concludes that VAM has the potential to revolutionize the machining process, making it more efficient and precise. Further research is recommended to fully understand the underlying mechanisms and optimize VAM parameters for various materials and machining processes. This will pave the way for broader adoption of VAM in industrial applications.
