Abstract
In the manufacturing industry, machine tools play a very important role. Many companies are searching for these machines in order to increase their competitiveness. They should be flexible, highly accurate, productive, ecological and cost efficient. At present, the traditional machine tool cannot fulfil such demands as they achieve either high flexibility or high accuracy. However, since the 90’s, Parallel Kinematics Machines (PKM) appear in real production. These machines have many advantages over the conventional machine tools and serial kinematics robots, such as high flexibility, high stiffness, and high accuracy. PKM development is considered as a key technology for future robot applications in manufacturing industries. In this paper, we present various kinematics of PKM with their advantages and their disadvantages. Then, to achieve better accuracy and dynamic performance for both light machining and heavy machining and in order to reconfigure the machine quickly for task changes the static and dynamic performance must be better understood. So we study accuracy and dynamic performance and the impact during machining. We establish a model of static and dynamic properties, which can provide the tool for mechanical designers and the controller designers to evaluate the machine. This research work is related to industrial applications. What is considered in this work is the problem as encountered by the machine end user. The results obtained will benefit the machine end user in industry. The study of PKM in the production environment is a new topic in the PKM research area.
