Parallel Kinematic Machines (PKMs) are one of the most radical innovations in production equipment. They attempt to combine the dexterity of robots with the accuracy of machine tools to respond to several industrial needs. This book contains the proceedings of the first European-American Forum on Parallel Kinematic Machines, held in Milan, Italy from 31 August - 1 September 1998. The Forum was established to provide institutions, technology suppliers and industrial end users with an improved understanding of the real advantages to be gained from using PKMs. This book contributes to a mid-term strategy oriented to reduce time to market and costs, improve production flexibility and minimize environmental impacts to increase worldwide competitiveness. In particular the authors focus on enabling technologies and emerging concepts for future manufacturing applications of PKMs. Topics include: Current status of PKM R&D in Europe, the USA and Asia. Industrial requirements, roadblocks and application opportunities. Research issues and possibilities. Industrial applications and requirements.

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.

Parallel Kinematics- Type, Kinematics, and Optimal Design presents the results of 15 year's research on parallel mechanisms and parallel kinematics machines. This book covers the systematic classification of parallel mechanisms (PMs) as well as providing a large number of mechanical architectures of PMs available for use in practical applications. It focuses on the kinematic design of parallel robots. One successful application of parallel mechanisms in the field of machine tools, which is also called parallel kinematics machines, has been the emerging trend in advanced machine tools. The book describes not only the main aspects and important topics in parallel kinematics, but also references novel concepts and approaches, i.e. type synthesis based on evolution, performance evaluation and optimization based on screw theory, singularity model taking into account motion and force transmissibility, and others. This book is intended for researchers, scientists, engineers and postgraduates or above with interests in robotics and advanced machine tools technology such as parallel kinematics machines (PKMs).

The paper has presented a complete methodology for the identification of the geometrical parameter set necessary to describe inaccuracy in the kinematic structure of a generic parallel manipulator. The methodology, that can be applied to any existing PKM, supplies a minimum, complete and parametrically continuous model of the manipulators. It can be applied both to intrinsic (internal) and extrinsic (external) calibration. The methodology identifies the parameters describing geometric errors of the manipulator, joint offset errors and errors in the external devices used for calibration (e.g. double ball bar). Furthermore, a general formula to determine the total number of necessary parameters has been presented and discussed. The paper shows how for some manipulators the number of parameters that are theoretically necessary is quite large and a numerical methodology to remove the less significant is mentioned. The final methodology is general and it is an algorithm, this means that it can be automatically applied to any given PKM. Numerous practical explicative examples are also given.

The aim of using parallel kinematic motion systems as an alternative of conventional machine tools for precision machining has raised the demands made on the accuracy of identification of the geometric parameters that are necessary for the kinematic transformation of the motion variables. The accuracy of a parallel manipulator is not only dependent upon an accurate control of its actuators but also upon a good knowledge of its geometrical characteristics. As the platform's controller determines the length of the actuators according to the nominal model, the resulted pose of the platform is inaccurate. One way to enhance platform accuracy is by kinematic calibration, a process by which the actual kinematic parameters are identified and then implemented to modify the kinematic model used by the controller. The first and most general valuation criterion for the actual calibration approaches is the relative improvement of the motion accuracy, eclipsing the other aspects to pay for it. The calibration outlay has been underestimated or even neglected for a long time. The scientific value of the calibration procedure is not only in direct proportion to the achieved accuracy, but also to the calibration effort. These demands become particularly stringent in case of the calibration of hexapods of the so-called simple design. The objectives of the here proposed new calibration procedure are based on the deficits mentioned above under the special requirements due to the circumstances of the simple design-concept. The main goals of the procedure can be summarized in obtaining the basics for an automated kinematic calibration procedure which works efficiently, quickly, effectively and possibly low-cost, all-in-one economically applied to the parallel kinematic machines. The problem will be approached systematically and taking step by step the necessary conclu-sions and measurements through: Systematical analysis of the workspace to determine the optimal measuring procedure, meas.
