This paper describes a micro grinding method using a Poly Crystalline Diamond (PCD) micro tool scanning on a high accuracy 3 axis machine platform. An accurate tool can be shaped using micro EDM. The EDM process can produce many tool shapes, therefore complex three dimensional microstructures can be realized.

In this paper, a prediction model of the material removal depth for the polishing process is developed from the microscopic point of view. Based on the statistics analysis, and by the use of the elastic contact theory and the plastic contact theory, the relationship between the pressure and the depth of indentation is obtained. Moreover, the calculation equation for the …

During grinding a large number of micrometer or sub-micrometer grains remove material from the surface of a workpiece, acting as cutting tools. As the grains perform the material removal process, the alterations on the workpiece surface are correlated to the grain characteristics, as well as process parameters. In the case of nano-grinding, only several atomic layers are …

Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used. Grinding is quick and relatively easy process but can
