Abstract
Parallel structured machine tools are known as a new generation multi-axis machining centre in manufacturing for the 21st century, but because of the complex mechanisms their performance development is limited by the existing mathematical algorithms, measurement technique and calibration method. In current researches, the methods for forward kinematics of parallel mechanisms still have difficult procedures and multi-solutions due to the nonlinear mathematical properties and are unlikely used in kinematics control for parallel structured machine tools. Therefore, in terms of the mechanism features, an analysis model for 6-3 Stewart platform machine tools is established to obtain the kinematics and statics solutions. In particular, 3 extra symmetrically located displacement sensors are used for direct kinematics resolution combining some special geometrical operations, hence closed form solution for forward kinematics is implemented and corresponding numerical simulations are developed.
