Abstract: In this article a new ultrasonic machining process is presented. The tool is a diamond impregnated sonotrode, which is split at the end, so that it makes both lateral and longitudinal vibrations. Machining experiments were performed with glass, alumina and partially stabilized zirconia (PSZ). Material removal rates were highest for glass and alumina, at approximately 600 mm³/min with R_a-values ranging from 1.6 to 2.1 μm. The material removal mechanism for glass and alumina was microfracture. The best surface quality was obtained with PSZ, but material removal rates were low. The material removal mechanism was controlled by plastic deformation.
