This book, based on the Fourth International Conference on Advanced Manufacturing Systems and Technology - AMST '96 aims at presenting trend and up-to-date information on the latest developments - research results and industrial experience in the field of machining processes, optimization and process planning, forming, flexible machining systems, non conventional machining, robotics and control, measuring and quality, thus providing an international forum for a beneficial exchange of ideas, and furthering a favourable cooperation between research and industry.

Matthew J. Liberatore Department of Management Villanova University Villanova, PA 19085 1. BACKGROUND The weakening competitive position of many segments of u.s. manufacturing has been analyzed, debated and discussed in corporate boardrooms, academic journals and the popular literature. One result has been a renewed commitment toward improving productivity and quality in the workplace. The drive to reduce manufacturing related costs, while meeting ever-changing customer needs, has led many firms to consider more automated and flexible manufacturing systems. The extent to which these new technologies can support business goals in productivity, quality and flexibility is an especially important issue for manufacturing firms in the u.s. and other Western nations. Problems have arisen in developing performance measures and evaluation criteria which reflect the full range of costs and benefits associated with these technologies. Some would argue that managerial policies and attitudes, and not the shortcomings of the equipment or manufacturing processes, are the major impediments to implementation (Kaplan 1984).

Manufacturing a product is not difficult, the difficulty consists in manufacturing a product of high quality, at a low cost and rapidly. Drastic technological advances are changing global markets very rapidly. In such conditions the ability to compete successfully must be based on innovative ideas and new products which has to be of high quality yet low in price. One way to achieve these objecti ves would be through massive investments in research of computer based technology and by applying the approaches presented in this book. The First International Conference on Advanced Manufacturing Systems and Technology AMST87 was held in Opatija (Croatia) in October 1987. The Second International Conference on Advanced Manufacturing Systems and Technology AMSV90 was held in Trento (Italy) in lune 1990. The Third, Fourth, Fifth and Sixth Conferences on Advanced Manufacturing Systems and Technology were all held in Udine (Italy) as follows: AMST93 in April 1993, AMST96 in September 1996, AMST99 in June 1999 and AMST02 in June 2002.

This work reviews the basic concepts of co-ordinate metrology. It defines what co-ordinate measuring machines (CMMs) are and details how they can be applied to gain a competitive advantage in a variety of business settings, from small machine shops to global manufacturers. Areas that are critical for the successful application of CMMs - including environmental factors, the measuring of speed and accuracy, traceability, versatility and programming methodology - are considered.;The book is intended for manufacturing, mechanical, quality control, design, industrial, automation, automotive and aerospace engineers and managers, as wel as upper-level undergraduate and graduate students in these disciplines.;College or university bookstores may order five or more copies at a special student price, which is available from Marcel Dekker Inc upon request.

This book focuses on effective methods for assessing the accuracy of both coordinate measuring systems and coordinate measurements. It mainly reports on original research work conducted by Sladek’s team at Cracow University of Technology’s Laboratory of Coordinate Metrology. The book describes the implementation of different methods, including artificial neural networks, the Matrix Method, the Monte Carlo method and the virtual CMM (Coordinate Measuring Machine), and demonstrates how these methods can be effectively used in practice to gauge the accuracy of coordinate measurements. Moreover, the book includes an introduction to the theory of measurement uncertainty and to key techniques for assessing measurement accuracy. All methods and tools are presented in detail, using suitable mathematical formulations and illustrated with numerous examples. The book fills an important gap in the literature, providing readers with an advanced text on a topic that has been rapidly developing in recent years. The book is intended for master and PhD students, as well as for metrology engineers working at industrial and research laboratories. It not only provides them with a solid background for using existing coordinate metrology methods; it is also meant to inspire them to develop the state-of-the-art technologies that will play an important role in supporting quality growth and innovation in advanced manufacturing.
