This paper presents an initial study on high speed meso scale milling of ZrO2 ceramics with diamond coated corner radius end mills. The obtained surface roughness under various milling parameters and the corresponding surface topographies are examined towards an in-depth understanding of the cutting mechanism. Mirror surface quality on ceramics is achieved by diamond milling, and the average surface roughness of the machined floor ranges from 0.025 μm to 0.066 μm Ra. The milled surfaces show regular and smooth feed marks, which indicate that material is removed in ductile mode. The quality of the surface roughness versus the tool machining time is also monitored.
