Al2O3 and ZrO2 based ceramics are extremely difficult to manufacture, being rotary ultrasonic machining (RUM) an interesting machining process for these materials. In this work the effect of RUM on the final surface integrity of ZrO2–TiN and Al2O3–TiC–SiC ceramics has been studied. During RUM of these ceramics two material removal modes co-exist: brittle and ductile fracture. In Al2O3–TiC–SiC prevails...
