Influence on surface quality in milling of green stage zirconia for dental products

Dejkun, Vitali and Dietz, Sören and Abele, Eberhard (2015):
Influence on surface quality in milling of green stage zirconia for dental products.
In: Applied Mechanics and Materials, Trans Tech Publications, Switzerland, pp. 201-206, 794, [Article]

Abstract

The following article gives an overview on the manufacturing challenges of milling green stage zirconia. Significant influence factors on the surface quality like machine type, cutting parameters, milling strategy and post processing were investigated. The results show a minimal influence of the machine type. Furthermore, machining zirconia with high cutting speed and low cutting depth achieves best results for surface quality. Tool wear and milling strategies have major influences on surface roughness and chipping. The combination milling strategy leads to material cracks and has negative impacts on the surface quality. Post processes like polishing and sintering improves surface roughness by 50 after the milling.
