This paper took a kind of 3-TPT Parallel Machine Tool (PMT) as the object of research, and it mainly researched the measurement method to position coordinates of movable platform in PMT. First the paper introduced the structure of 3-TPT PMT. Then illustrated the device structure and the basic measurement principle for measuring the position coordinates of movable platform. Finally carried on the theoretical analysis to the specific measurement method and established the corresponding mathematics relationship. The measurement method that was presented in this paper had characteristics of simple structure, convenient and flexible operation, economical and so on, and simultaneously the research results of this paper laid a theoretical foundation for improving the movement precision of this PMT and had important practical significance |
