Opis

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.
