by Professor Pat McKeown Cranfield Precision Engineering, UK Member of Joint Organising Committee IPES6/UME2 PROGRESS IN PRECISION ENGINEERING Metal working companies in tool making, prototype manu facture and subcontract machining often use the label "precision engineering" to indicate that they are accustomed to working to finer tolerances than is normally expected in series production. But what we are concerned with in this and our preceding international conferences is much wider and deeper than this. Precision engineering is a grouping of multidis ciplinary scientific and engineering skills and techniques, firmly based on dimensional metrology, by which a wide range of new advanced technology products is made possible. In the last 5 - 10 years we have witnessed dramatic progress in precision engineering, particularly by the rapid development of its important sub-sets, micro-engineering and nanotechnology. I t is a part icular pleasure for me and my colleagues on the Organising Committee to welcome you to Braunschweig on the occasion of this the first joint international meeting in high precision manufacturing/precision engineering to be held in Germany. Our aim is to bring together the world's leading precision engineering practitioners from areas of application as diverse as optics for astronomy, micro and nano machining process research, design and development of ul tra preclslon machine tools and metrology equipment, advanced materials, bio medical research and new sensor/transducer systems.

Advances in engineering precision have tracked with technological progress for hundreds of years. Over the last few decades, precision engineering has been the specific focus of research on an international scale. The outcome of this effort has been the establishment of a broad range of engineering principles and techniques that form the foundation of precision design. Today’s precision manufacturing machines and measuring instruments represent highly specialised processes that combine deterministic engineering with metrology. Spanning a broad range of technology applications, precision engineering principles frequently bring together scientific ideas drawn from mechanics, materials, optics, electronics, control, thermo-mechanics, dynamics, and software engineering. This book provides a collection of these principles in a single source. Each topic is presented at a level suitable for both undergraduate students and precision engineers in the field. Also included is a wealth of references and example problems to consolidate ideas, and help guide the interested reader to more advanced literature on specific implementations.

This monograph written by two Chinese scientists of the younger generation opens a window into the world of thoughts on Mechanical Metallurgy in this fascinating area of our world, characterized by age old cultural heritage as weil as by its dynamic evolution into the future. Based on notions and names all so familiar to the western scientist, and regarding the subject from the point of view of the theoretical mechanical engineer (Yang) as weil as that of the materials and manufacturing engineer (Lee), the authors present a synthesis of both approaches and endeavour to guide the reader from basic theory to engineering applications. Between structural defects in the micrometer scale and the meter-measures of engineering components, the term of mesoplasticity is meant to place the reader right in the center: This is certainly achallenging enterprise, and the editor expresses his sincere wishes as to enrichment and stimulation which will emanate from this interesting book and its creative perspective. Prof. B. Ilschner March, 1993. Preface In the past two decades, enormous advances in materials and manufacturing tech nology have been achieved, which upgrade the material design, processing and precision manufacturing as quantitative and concise scientific disciplines. Rapid improvements on mechanics understanding have been instrumental in the above mentioned development. A topic of great interest and importance in plasticity re search has been the design and processing of materials themselves on the mesoscale to achieve the desired macroscopic properties.
“Another gem from one of the world’s justly celebrated historians specializing in unusual and always fascinating subjects and people.” — Booklist (starred review) The revered New York Times bestselling author traces the development of technology from the Industrial Age to the Digital Age to explore the single component crucial to advancement—precision—in a superb history that is both an homage and a warning for our future. The rise of manufacturing could not have happened without an attention to precision. At the dawn of the Industrial Revolution in eighteenth-century England, standards of measurement were established, giving way to the development of machine tools—machines that make machines. Eventually, the application of precision tools and methods resulted in the creation and mass production of items from guns and glass to mirrors, lenses, and cameras—and eventually gave way to further breakthroughs, including gene splicing, microchips, and the Hadron Collider. Simon Winchester takes us back to origins of the Industrial Age, to England where he introduces the scientific minds that helped usher in modern production: John Wilkinson, Henry Maudslay, Joseph Bramah, Jesse Ramsden, and Joseph Whitworth. It was Thomas Jefferson who later exported their discoveries to the fledgling United States, setting the nation on its course to become a manufacturing titan. Winchester moves forward through time, to today’s cutting-edge developments occurring around the world, from America to Western Europe to Asia. As he introduces the minds and methods that have changed the modern world, Winchester explores fundamental questions. Why is precision important? What are the different tools we use to measure it? Who has invented and perfected it? Has the pursuit of the ultra-precise in so many facets of human life blinded us to other things of equal value, such as an appreciation for the age-old traditions of craftsmanship, art, and high culture? Are we missing something that reflects the world as it is, rather than the world as we think we would wish it to be? And can the precise and the natural co-exist in society?
Sensing Approaches for Precision Agriculture aims to bring together the ‘state of the art’ of the most popular sensing techniques and the current state of research on the application of sensors in Precision Agriculture (PA). Sensing is of great value in PA because it provides cheap and immediate data for management. This book gives a broad overview of sensing in PA and a coherent introduction for new professionals and research scientists. Readers are introduced to the potential applications of a range of different sensors, how they should be used properly and their limitations for use in PA.

Since the 18th century, automation has driven progress in manufacturing, transforming the workplace and contributing to the massive increase in living standards enjoyed by most people in the developed world over this period. A robot is a specific example of automation technology, one that can perform a complex sequence of actions automatically without manual intervention. Originally confined to manufacturing, robotic technology is now entering many other areas of our lives, from our domestic appliances to medical devices, and recent developments in self-driving vehicles are bringing some of the most sophisticated examples of the technology onto our roads. The Story of the Robot examines the history of the robot within the wider context of automation, thereby allowing the reader to fully appreciate the origins and evolution of robotic systems. It begins by tracing the historical roots of robotics through the development of automata and mechanical toys. The next four chapters guide the reader on a whistle-stop tour across more than 300 years of automation history. Chapter 6 charts the rise of humanoid robots, beginning with their first appearance in science fiction stories to their physical realisation at the end of the 20th century. In Chapter 7, the use of autonomous control technology in mobility applications is surveyed, from the earliest self-steering vehicles to autonomous robots and self-driving cars. The final chapter brings the story up to date with the new industrial revolution now taking place as a result of the application of digitalisation and interconnectivity technologies to manufacturing. Each chapter contains a selection of carefully chosen images and includes a further reading list for those readers who wish to delve deeper into the technical details.
