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.

This book contains the research report of the DFG Research Unit FOR 1845 (2014-2020) of the Universities of Bremen and Hannover. The thematic focus lies on speeding up ultra-precision machining technology by following a holistic approach to high-performance cutting. This includes ultra-precision milling at high spindle speeds (>10000 rpm), precision tool setting mechanisms for multi-cutting-edge diamond milling tools, magnetic levitation technology for high velocity feed axes, and dedicated control strategies for error identification and compensation at high speeds. Furthermore, automation and measurement aspects of the machine setup process especially for precision balancing of the spindle rotors are presented. Finally, it is demonstrated that how the developed technologies may be integrated into a common machine tool setup. The target audience primarily comprises research experts and practitioners in production engineering, but the book may also be of interest to graduate students alike.

This book presents the latest information on the intelligent CNC machine tool spindle system, which integrates various disciplines such as mechanical engineering, control engineering, computer science and information technology. It describes a prediction method and model for temperature rise and thermal deformation in motorized spindles and proposes an intelligent stator resistance identification method to reduce the torque ripple of motorized spindles under direct torque control. Further, it discusses the on-line dynamic balance method for NC machine tool spindles. The biogeographic optimization algorithm and hybrid intelligent algorithm presented here were first applied in the field of motorized spindle performance control. In turn, the book presents extensive motorized spindle performance test data and includes detailed examples of how intelligent algorithms can be applied to motor spindle stator resistance identification, temperature field prediction and on-line dynamic balance. In summary, the book provides readers with the latest tools for designing, testing and implementing intelligent motorized spindle systems in terms of the basic theory, technological applications and future prospects, and offers a wealth of practical information for researchers in mechanical engineering, especially in the area of control systems.
