Abstract
ZrO2-based ceramics are extremely difficult to manufacture, rotary ultrasonic machining (RUM) being an interesting machining process for these materials. In this work, ZrO2-NbC and ZrO2-WC ceramic composites have been RUM-processed and the differences in cutting forces, surface quality and dominant machining mechanisms under different machining operations and conditions have been studied. In ZrO2-NbC, the presence of the ductile fracture material removal mode is more evident than in ZrO2-WC, where the brittle fracture mode seems to be dominant. This contributes to a slightly better machinability of ZrO2-NbC compared to ZrO2-WC, what results in slightly higher material removal rates (MRR) and lower surface roughness.
