The Measurement Method to Position Coordinates of Movable Platform for 3-TPT Parallel Machine Tool

Abstract:

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 measuring device that was presented in this paper had characteristics of direct-viewing measurement relationship, simple structure and low cost etc., 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.
