The present work presents the results obtained when an ultrasonic vibration is applied to tool on the turning of mild steels. Currently high‐end materials, usually present low machinability so it is necessary to employ new machining technologies. Ultrasonic assisted turning (UAT) is presented as an effective process for machining these difficult‐to‐cut materials. In order to achieve a better understanding of the process, a complete study of the influence of the vibration parameters is presented when machining mild steels. Several parameter of UAT were monitored, including surface roughness, tool wear, chip formation by a high‐speed imaging camera, and tool temperature by means of an infrared camera: surface roughness and tool temperature decrease and an tool life increase as compared to conventional turning (CT).
