碩士 === 國立交通大學 === 機械工程系 === 87 === Abstract Liberated Coordinate Measuring Machine is a articulated type 3D coordinate measurement system which is able to measure the coordinate of a object surface for geometry modeling and locate the position in space by using six degrees of freedom arm. The accuracy improvement and manipulability performance are concerned in present study. The precision of the kinematics parameters of the system may influence the performance of practical measurement. In this thesis, we propose a valuable method to find the actual kinematic parameter data and then replace them into the parameter table to improve measurement precision. We also present a methodology to investigate and improve manipulability of the system. After calibrating process and a series of manipulability simulation, we propose some comments from design and implement aspects for better precision and practical application on the Liberated Coordinate Measuring Machine.
