In this case, the effect of micro structure of work material on a removal mechanism involved in the micro grinding process and the pragmatic technologies for making aspherical micro moulds are discussed in detail. The chapter focuses on the development of truing and dressing technologies for micro grinding wheels.

The kinematic overlapping of the tool rotation with an additional oscillation effects a reduction of the process forces by up to 40% in comparison to conventional machining. Depending on the work-piece requirements, this allows higher feed rate, provides longer tool …

Diamond tools are fabricated by brazing and used to machine dental ceramics in this paper. The morphology, grinding ratio, wear and grinding force of the brazed tools are investigated in comparison with that of the electroplated ones. The results show that the brazed alloy forms a hill-like structure around the diamond grits, and the protrusion of the brazed diamond grits is higher than that ...

In this study, micro-grinding was performed to investigate the machining characteristics of alumina and zirconia. The machining of ceramics remains highly challenging owing to their properties, such as high brittleness and wear resistance, which leads to a shorter tool life and high machining costs.
