Actual development trends demonstrate the use of microstructures or functional surfaces/defined surface properties in molds, forms and dies (e.g. for micro injection molding, hot embossing, sheet metal forming) , product identification or the use of micro parts for medical applications (individual micro implants) which require reliable and repeatable micro and precision machining technologies especially in metal cutting processes. Nevertheless hard to machine high strength materials (hardened steel, tungsten carbide, and titanium, ceramic) which are usually required for such applications challenging associated machining technologies. Material based machining strategy is the first main influencing variable and the development of adapted process chains is object of research by Fraunhofer IWU and ENIMS in the frame of Russian-German Innovative project IWUMASH. Further the associated machine tools are the second influencing variable to guarantee necessary geometrical tolerances and surface qualities for micro and precision applications. In this context machine tools for cutting processes (µ-milling, µ-drilling, Fly-Cutting, Nano-Hobbing) and ablation processes (µ-laser, µ-EDM and ECM) are developed and enhanced by Kugler GmbH, ENIMS and Fraunhofer IWU. This paper presents the results of different machining applications for very small microstructured parts (e.g. inner ear implant) but also very precise bigger parts with a lot of identical microstructures or defined surface properties (e.g. mirrors, mold for carbody parts). Technologies and innovative hybrid processes for the flexible, process-reliable and economical production of functional surfaces and microstructures on precision components as well as systems for medical engineering and micro-analytics will be introduced as an aspect for future cooperation between Russian and German partners.
