Abstract
Micromachining, due to the miniaturization of the tools, is subject to a large variety of specific influencing factors. These factors essentially affect accuracy and surface quality of microstructured moulds and prototypes. Especially the machining of high strength materials is so far not sufficiently controllable to guarantee reliability and repeatability for complex microstructured parts. The influence of these factors can be improved by an aligned process control. Particularly the choice of milling strategies and the associated process parameters is essential. Within the paper different milling strategies, depending on the machined geometry, will be discussed. The influence of strategy and process parameters on surface quality and accuracy of complex, hreedimensionally structured parts is demonstrated on a microstructured mould. Reasons for surface and accuracy failures are shown and strategies to avoid them are exemplified.
