This book was released on 2008 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent developments in diamond machining technology have enabled significant expansion of fabrication capabilities. Ultraprecision diamond machining centers with multiple degrees of freedom can generate free-form solids with optical surface finishes and features on scales ranging from the centimeter to the sub-micrometer level and accuracies in the 10s of nanometers on a single component using one machine. One area of application for ultraprecision diamond machining is for the fabrication of complex micro-optics devices and structures that are difficult to produce using the more conventional lithographic techniques for micro-optics production. The advantages in flexibility and form, the ability to meet the strict requirement of micro-optics fabrication, and the relative low cost of diamond machine tools (compared to that of lithography machines) have the potential to revolutionize the manufacture of many micro-optical devices, whilst also serving as an enabling technology for new types of components and systems in other fields. This work serves to advance the experience and capabilities of ultraprecision diamond machining while discussing techniques and applications of the fabrication of small scale optical elements in germanium for infrared imaging applications. Diamond tool design and cutting parameter requirements were determined for the ductile-regime machining of germanium, a crystalline and brittle material. Systematic cutting tests using varying parameters were completed to evaluate the effect of feed, cutting speed, and crystal orientation on the surface finish of diamond turned germanium. It was shown that for ductile-regime cutting, feed is the primary influence on surface finish. Single crystal diamond tools with rake angles of -25[degree] to -45[degree] and radii of 100 [mu]m to 800 [mu]m were used with combinations of depths of cuts ranging from 1 [mu]m to 20 [mu]m and feeds ranging from 0.5 [mu]m/rev to 3 [mu]m/rev to successfully generate ductile-regime cutting conditions. A surface finish of 0.7 nm RMS was realized for a 5 [mu]m depth facing cut using a 0.381 mm radius diamond tool with a -25[degree] rake angle at a 1 [mu]m/rev feed. Examples parts are also presented, including the fabrication of an aspheric lens array in germanium for a compact infrared imaging system that was enabled through the performed experiments. Using custom kinematic mounting equipment and the additional axes of the Moore Nanotechnology 350 FG machine, the lenses were turned with a surface finish better than 2 nm RMS and a center to center positioning accuracy of [plus or minus]0.5 mm. Future work is also discussed, including initial testing for one potential next step to further advance the field of ultraprecision diamond machining.

Available in PDF, EPUB and Kindle. Book excerpt: An Engineering Research Series title. One of the remarkable achievements of modern manufacturing techniques is the ability to achieve nano-metre surface finishes. Ultraprecision machining based on single-point diamond turning (SPDT) is a very important technique in the manufacture of high-precision components where surface finish is critical. Complex optical surfaces, for example, can be produced without the need for post-machining polishing. This book focuses on the aspect of modelling nano-surface generation in ultra precision SPDT. Potential industrial applications in the prediction of surface quality, the process optimization, and precision mould manufacturing are also studies. The essential differences between single-point diamond turning and conventional machining are described. The history and technology of single-point diamond turning are presented and single chapters emphasize the related metrology and cutting mechanics. Important aspects of surface generation are also discussed. Features of the text are the sound approach, systematic mathematical modelling, and computer-aided simulation of surface generation in the development of surfaces exhibiting nano-surface qualities. TOPICS COVERED INCLUDE: Fundamentals of ultra-precision diamond turning technology Cutting mechanics and analysis of microcutting force variation Mechanisms of surface generation Characterization and modelling of nano-surface generation Computer-aided simulation of nano-surface generation Diamond turning of aspheric optics. Based upon the extensive experience of the authors Surface Generation in Ultra-precision Diamond Turning: Modelling and Practices will be of interest to engineers, scientists, and postgraduate students.
