Development of a tertiary motion generator for elliptical vibration texturing

► An innovative process is proposed for the fast generation of structured surfaces. ► The new process utilizes controlled elliptical vibrations of the cutting tool. ► The piezo transducer delivers an elliptical trajectory at an ultrasonic frequency. ► The device has two coupled vibration modes at nearly the same frequency. ► Micro dimple arrays have been created by the developed device.
