The rise in complexity of freeform optics has driven the development of equally complex manufacturing processes needed to produce them. From freeform lens molds, to large freeform mirrors, to steep microlens arrays on non-flat base surfaces, optics manufacturing has traditionally been time-consuming and error prone – often requiring hand lapping and polishing – to produce optics to their final shape. Due to its inherent precision, deterministic nature, and net shape capabilities, ultraprecision diamond machining (UPDM) has matured into a highly preferred and reliable method for the direct machining of freeform optics. However, complex optical surfaces require equally complex machining toolpaths and techniques that can generate them. The goal of this research is to develop enabling technologies that vastly improve existing toolpath generation techniques for freeform optics. These new technologies allow complex optical surfaces, natively described by explicit surface equations and defined inside arbitrary boundaries, to be efficiently machined. To this end, studies on both the distribution of points that define a set of independent coordinates (Cartesian XY or polar R¿) and the calculation of dependent coordinates – optical sag values – are considered. Each study had its own objectives of reducing machining cycle time and machine tool accelerations/following error without sacrificing surface finish.

This thesis focuses on producing hybrid freeform surfaces using an advanced diamond-turning process, understanding the generation of surface accuracies (form errors) and how the choice of cutting strategies affects these, as well as simplifying the complications of generating cutting paths for such freeform surfaces. The breakthroughs behind this thesis are the development of novel, multiple-axis, diamond turning techniques to overcome the limitations of conventional diamond turning processes, an analytical model to optimize the generation of ultraprecise freeform surfaces, and an add-on tool path processor for CAD/CAM software solutions. It appeals to researchers and scholars with a strong machining background who are interested in the field of manufacturing ultraprecise freeform surfaces or in the field of optimizing ultraprecision machining processes.

This handbook covers the fly cutting technique, an ultra-precision mechanical machining technology which is regarded as the fastest and most reliable low-cost machining method to generate high quality complex surfaces. The ultra-precision raster milling provides more flexibility and suitability for freeform and structural surfaces with a uniform quality with sub-micrometric form error and nanometric surface roughness. These surfaces are widely applied into optics, medicine, biotechnology, electronics, and communications. The fundamental and latest advancing knowledge of fly-cutting technology is important for the future development and applications in ultra-precision mechanical machining technology. This book provides a good reference for fly-cutting technology in ultra-precision machining for undergraduate and postgraduate students, researchers, engineers, and postdoctoral fellow in advanced manufacturing area. It gives the audience an overview of the working principles, process mechanism, salient features, applications, and research directions of ultra-precision fly-cutting technology.

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.
