Machines Mechanism (EPT 314/3)

This book contains the papers of the European Conference on Mechanisms Science (EUCOMES 2012 Conference). The book presents the most recent research developments in the mechanism and machine science field and their applications. Topics addressed are theoretical kinematics, computational kinematics, mechanism design, experimental mechanics, mechanics of robots, dynamics of machinery, dynamics of multi-body systems, control issues of mechanical systems, mechanisms for biomechanics, novel designs, mechanical transmissions, linkages and manipulators, micro-mechanisms, teaching methods, history of mechanism science and industrial and non-industrial applications.This volume will also serve as an interesting reference for the European activity in the fields of Mechanism and Machine Science as well as a source of inspirations for future works and developments.

Research and development of various parallel mechanism applications in engineering are now being performed more and more actively in every industrial field. Parallel robot based machine tools development is considered a key technology of robot applications in manufacturing industries. The material covered here describes the basic theory, approaches, and algorithms in the field of parallel robot based machine tools. In addition families of new alternative mechanical architectures which can be used for machine tools with parallel architecture are introduced. Given equal importance is the design of mechanism systems such as kinematic analysis, stiffness analysis, kinetostatic modeling, and optimization.

Machine Tool Vibrations and Cutting Dynamics covers the fundamentals of cutting dynamics from the perspective of discontinuous systems theory. It shows the reader how to use coupling, interaction, and different cutting states to mitigate machining instability and enable better machine tool design. Among the topics discussed are; underlying dynamics of cutting and interruptions in cutting motions; the operation of the machine-tool systems over a broad range of operating conditions with minimal vibration and the need for high precision, high yield micro- and nano-machining.

Offering complete coverage of the technologies, machine tools, and operations of a wide range of machining processes, Machining Technologypresents the essential principles of machining and then examines traditional and nontraditional machining methods. Available for the first time in one easy-to-use resource, the book elucidates the fundamentals, basic elements, and operations of the general purpose machine tools used for the production of cylindrical and flat surfaces by turning, drilling and reaming, shaping and planing, milling, boring, broaching, and abrasive processes.

This book starts with the invention of the wheel nearly 5000 years ago, and via Archimedes, Aristotle and Hero describes the first practical applications such as water wheels and grinding wheels, pushing on to more rigorous scientific research by inquiring minds such as Leonardo da Vinci and Copernicus in later ages. Newton and Leibniz followed, and beam structures received maximum attention three centuries ago. As focus shifts and related disciplines such as mathematics and physics also develop, slowly turbomachines and rotor and blade dynamics as we know the subject now take shape. While the book traces the events leading to Laval and Parsons Turbines, the emphasis is on rotor and blade dynamics aspects that pushed these turbines to their limits in the last century. The tabular and graphical methods developed in the pre-computer era have taken different form in the last fifty years through finite element methods. The methods evolved in the last century are discussed in detail to help modern day designers and researchers. This book will be useful to young researchers and engineers in industry and educational institutions engaged in rotor and blade dynamics work in understanding the past and the present developments and what is expected in future. Faculty and industry engineers can benefit from this broad perspective history in formulating their developmental plans.

This work deals with mechanical manufacturing processes in history, examined through the machines associated with those processes. A tool is only included if it is part of a machine tool, with devices made up of moving parts. Once the analytical field has been marked out, the chosen descriptive method is basically graphic.This historical compendium attempts to give a wide-angle view of historical development without making an in-depth analysis of each of the examples presented. Moreover, this book illustrates the historical development of machines and mechanisms more from a technical point of view rather than a strictly history of science point of view since the authors are mechanical engineers who are interested and motivated to examine the most significant facts in their own area of knowledge of the Theory of Machines and Mechanisms. A full understanding of the historical development of Technology also needs the help of experts in technical matters who can appreciate and reassess bygone achievements in the light of their own technical knowledge. More collaboration between science historians and technical experts is needed, as is currently the case in the field of Industrial Archaeology. Thus, this book is also an attempt to set out a technical approach to the historical development of machines and mechanisms, but without too many technical details that will prevent its understanding being purely historical.At the beginning of each chapter there is a global reference to the period embraced, the most relevant facts, and the most significant treatises in the context of machine history. Following this introduction each chapter contains a series of sections on the types of machines that are representative of the period analysed together with illustrations to accompany the text. A fairly extensive bibliography enables the reader to make a deeper historical analysis.
