The Influence of the Crystallographic Structure of the Substrate Material on Surface Quality and Cutting Forces in Micromachining

Ultra precision cutting is a machining method to manufacture mainly optical components with a surface roughness of a few nanometers and form tolerances which are in the submicron range. Due to continuous developments in the field of machine tools, it has become possible to machine increasingly complex surface contours. Thus, for example, recent efforts lead to the possibility to generate defined modulations on workpiece surfaces within the micron range by means of a piezoelectcrical fast-tool-servo (figure 1) [1]. As machining operations are becoming increasingly complicated, it is necessary to investigate the technological processes on the cutting edge more in detail.
