Micromachining of Molds for Manufacturing Optical Devices

There is an increasing interest in the development of new methodologies for mass-production of micro optics components. Among other methodologies, micro chip removal processes are promising in the realisation of complex shape molds. In this paper, the most important issues regarding application of micro machining processes suc as microturning, micromilling and microgrooving for manufacturing molds for optical devices are discussed. The differences between conventional and micro machining processes describing the main characteristics of tools, workpiece materials and machine tools for micro machining are also discussed. In addition, two case studies investigated at the Centro Ricerche Plast-Optica, Amaro, Italy, in collaboration with the University of Udine, are presented. The first case study illustartes the realization of brass inserts for molding of aspheric laser optics. The second case study decribes the production of micro prism master for manufacturing optical components.
