Machining of optics: an introduction.

Adaptable Five-Axis Polishing Machine Head

Introduction A growing demand on machining high precision aspherical and free-form optics derives from the continuous development of computer-assisted calculation and simulation methods and therefore improved possibilities of integrating numerous optical functions within one and the same lens or mirror. Applications include illustration as well as sophisticated illumination optics. State-of-the...

Direct Machining of Inner Reflecting Surface for a Soft X-ray Microscope

INTRODUCTION A soft X-ray microscope can be used to investigate hydrated specimens, particularly living cells, with a high resolution about several times better than that of a visible light microscope. It can also extend to material science, plasma fusion research, magnetic research, environment science, and so on. The reflecting optics used in a soft X-ray microscope requires supersmooth surfa...

Application of precision diamond machining to the manufacture of micro-photonics components

The use of diamonds to generate precision patterns and precision surfaces on a micrometer or nanometer scale has a history that dates back centuries. Uses of diamond in semi-automated machinery can be traced to ruling machines, pantographs, and ornamental turning with “diamond turning” dating back about a century. Poor behavior in machining more common materials (e.g. ferrous alloys) has limite...

Development of Design and Manufacturing Support Tool for Optimization of Ultrasonic Machining (USM) and Rotary USM

Ultrasonic machining (USM) is a mechanical material removal process used to erode holes and cavities in hard or brittle work pieces by using shaped tools, high-frequency and an abrasive slurry. This paper addresses the concept and development of an expert system (ES) for hard and brittle material, such as glass, quartz, diamond, carbides, semi conducting materials, ceramic and graphite which ca...
