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.

Abstract: The ultraprecision Single Point Diamond Turning (SPDT) technology has been developed for over 40 years and has been successfully applied to numerous fields. At present, the ultraprecision single point diamond turning technology already expanded to Single Point Diamond Machining (SPDM) technology, which includes several related processes in addition to the more conventional single point diamond turning. The other related processes are Fast Tool Servo (FTS), Slow Tool Servo (STS), broaching, and fly cutting. Though this technology has many notable merits, for example it can achieve micro meter or even sub micron form accuracy and nano meter surface roughness, there still has some drawbacks. One of the objectives of this research is to investigate one of these drawbacks, the diffraction and scattering of the ultraprecision single point diamond machined surfaces. Another objective is to extend the application of the SPDM by developing new design and new machining processes for freeform micro devices used in optical, mechanical, electronic, and biomedical fields. The mechanism and model of the ultraprecision single point diamond turning and micro cutting were first reviewed and discussed. The related subjects to the SPDT and micro cutting were also involved. The optical effects of diamond machined surfaces were studied. The diffraction and scattering generated from the diamond machined surfaces was analytically and experimentally studied. The influences from machining parameters, such as tool mark spacing, feedrate, spindle speed, tool radius, tool condition and different diamond machining process were considered. An empirical relationship between the machining conditions and the first order diffraction from the diamond machined surfaces was setup. This model can be used to select optimal machining conditions for diamond machining process. The design, machining and testing of microlens arrays by using SPDM process were introduced. Two microlens array examples were given. One is a 5 by 5 matrix arranged concave microlens array on flat brass substrate. The other one is a circular arranged 3D microlens array, which has 341 plano-convex micro lenslets, on a thin spherical PMMA substrate. Using the fabricated 3D microlens array, a 3D micro projection system was developed. The formed micro pattern dimension was 340 um by 460 um, giving an overall projection ratio of 34:1. It has been demonstrated that a low cost and simple manufacturing process for true 3D micro scale structures on non-planar substrates based on microlenses can be realized. Last but not least, an affordable polymer SAR micromixer was developed based on a high accuracy, low cost, and flexible micro machining process. Specifically both the mixing performance and the fabrication process were carefully studied. An improved design of the SAR micromixer was also given, the mixing efficiency of the two designs were 0.11 and 0.065 respectively.

High quality optical components for consumer products made of glass and plastic are mostly fabricated by replication. This highly developed production technology requires several consecutive, well-matched processing steps called a "process chain" covering all steps from mold design, advanced machining and coating of molds, up to the actual replication and final precision measurement of the quality of the optical components. Current market demands for leading edge optical applications require high precision and cost effective parts in large volumes. For meeting these demands it is necessary to develop high quality process chains and moreover, to crosslink all demands and interdependencies within these process chains. The Transregional Collaborative Research Center "Process chains for the replication of complex optical elements" at Bremen, Aachen and Stillwater worked extensively and thoroughly in this field from 2001 to 2012. This volume will present the latest scientific results for the complete process chain giving a profound insight into present-day high-tech production.
