✦ Synopsis

The aim of this article is to present a general survey of the processes that govern the ultrasonic machining of ceramics. The results are based on the drilling of holes in seven different ceramics and the aspects considered are production rate, tool wear, precision and surface quality. The investigations show that tough materials give a low production rate, a high tool wear, and a low surface roughness. For brittle materials the relationships are reversed; high production rate, low tool wear and high surface roughness. However, it is found also that there are important qualitative differences in the machined surfaces. Tough materials generally give material removal based on plasticity, and there seems to be a greater tendency for dense and non-porous materials to produce surfaces with texture.
