The parallel kinematic mechanism has been applied to simulators and robots for its high speed or multiple degrees of freedom. In recent years, however, it has begun to be used for precision mechanisms, such as machine tools, measuring machines, or fine-motion mechanisms. This review outlines the parallel kinematic mechanism and compares it with the conventional orthogonal coordinate mechanism to describe its nature and characteristics as a precision mechanism. It also introduces some cases in which the parallel kinematic mechanism is applied to fine motion mechanisms and three-dimensional coordinate measuring machines in addition to machine tools and robots. Finally, it discusses the problems and future of this parallel kinematic mechanism.
