This volume is about automation - automation in design, automation in manufacturing, and automation in production. Automation is essen tial for increased productivity of quality products at reduced costs. That even partial or piecemeal automation of a production facility can deliver dramatic improvements in productivity has been amply demon strated in many a real-life situation. Hence, currently, great ef forts are being devoted to research and development of general as well special methodologies of and tools for automation. This volume re ports on some of these methodologies and tools. In general terms, methodologies for automation can be divided into two groups. There are situations where a process, whether open-loop or closed-loop, is fairly clearly understood. In such a situation, it is possible to create a mathematical model and to prescribe a mathe matical procedure to optimize the output. If such mathematical models and procedures are computationally tractable, we call the correspond ing automation - algorithmic or parametric programming. There is, however, a second set of situations which include process es that are not well understood and the available mathematical models are only approximate and discrete. While there are others for which mathematical procedures are so complex and disjoint that they are computationally intractable. These are the situations for which heuristics are quite suitable for automation. We choose to call such automation, knowledge-based automation or heuristic programming.

This volume is based on the proceedings of the 28th International Conference on CAD/CAM, Robotics and Factories of the Future. This book specially focuses on the positive changes made in the field of robotics, CAD/CAM and future outlook for emerging manufacturing units. Some of the important topics discussed in the conference are product development and sustainability, modeling and simulation, automation, robotics and handling systems, supply chain management and logistics, advanced manufacturing processes, human aspects in engineering activities, emerging scenarios in engineering education and training. The contents of this set of proceedings will prove useful to both researchers and practitioners.

Presents state-of-the-art research and case studies from over 150 Design & Manufacturing professionals across the globe in the areas of CAD/CAM; Product Design; Rapid Prototyping and Tooling; Manufacturing Processes; Micromachining and Miniaturisation; Mechanism and Robotics; Artificial Intelligence; and Material Handling Systems.

Flexibility is as acceptable an objective for today's industrial community as is automation. Thus, the title of this conference proceedings volume - Flexible Automation - reflects an added emphasis to the usual industrial automation. As with general automation that has impacted every component of the manufacturing office and plant, the identity of flexible automation can possess various forms and functions. The papers in this volume have been grouped into two main categories. One category deals with implementation of so-called "intelligent manufacturing". This means use of algorithmic methods and artificial intelligence approaches to various problems encountered in practical factory automation tasks. The placement of papers into five chapters of this part cannot be very precise, due to multidisciplinary nature and constant rapid change of the field. The categories are arranged starting from problems of enhancement of current factory settings, and followed by the papers addressing more specific issues of production planning, process technology and product engineering. The fifth chapter contains papers on the very important aspects of factory automation - problems of design, simulation, operation and monitoring of manufacturing cells.

xiv box for Balanced Automation, research in this area is still young and emerging. In our opinion, the development of hybrid balanced solutions to cope with a variety of automation levels and manual approaches, is a much more challenging research problem than the search for a purely automatic solution. Various research activities described in this book illustrate some of these challenges through the development proposals, assisting tools, and initial results. In certain chapters however, the balancing aspects are not yet achieved in the research area, but their inclusion in this book is intended to give a broader and more comprehensive perspective of the multiple areas involved. One important aspect to be noticed is the extension and application of the concept of balanced automation to all areas of the manufacturing enterprise. Clearly, the need for a "balanced" approach is not restricted to the shop floor components, rather it applies to all other areas, as illustrated by the wide spectrum of research contributions found in this book. For instance, the need for an appropriate integration of multiple systems and their perspectives is particularly important for the implantation of virtual enterprises. Although both the BASYS'95 and the BASYS'96 conferences have provided important contributions, approaches, and tools for the implantation of balanced automation systems, there are a number of areas that require further research: .

The papers presented at the Second International Conference on Robotics and Factories of the Future held in San Diego, California, USA during July 28-31, 1987 are compiled in this volume. Over two hundred participants attended the conference, made technical presentations and discussed about various aspects of manufacturing, robotics and factories of the future. The number of papers published in this volume and the number of unpublished presentations at the conference indicates the evidance of growing interest in the areas of CAD/CAM, robotics and their role in future factories. The conference consisted of five plenary sessions, twenty three technical sessions, workshops, and exhibits from local industries and educational institutions. I wish to acknowledge with many thanks the contributions of all the authors who presented their work at the conference and submitted the manuscripts for publication. It is also my pleasure to acknowledge the role of keynote, banquet, and plenary sessions speakers whose contributions added greatly to the success of the conference. My sincere thanks to all session chairmen. I wish that the series of the International Conferences on Robotics and Factories of the Future which was initiated in 1984 in Charlotte, North Carolina will have a major impact on the use of robots and computers in the automated factories of the future.

In the competitive business arena companies must continually strive to create new and better products faster, more efficiently, and more cost effectively than their competitors to gain and keep the competitive advantage. Computer-aided design (CAD), computer-aided engineering (CAE), and computer-aided manufacturing (CAM) are now the industry standard. These seven volumes give the reader a comprehensive treatment of the techniques and applications of CAD, CAE, and CAM.
