The beam is an important component in agantry machining center, and its deformation is believed to have asignificant impact on both the machining accuracy and the machining performance. In this research, the finite element models of a complete gantry machining center and the crossbeam are established, in whicht he restraint and boundary conditions for the finite element analysis are also introduced. It is noted thatthe impact of balance cylinders on the key components is fully considered when dealing with the force analysis. Computed results of the static characteristic analysis showed that the maximum deformation is about 0.080925 mm when crossbeam operates under different conditions. Then, the distortion curve and the compensation curve of guide rail are obtained, and the equation of a fitting compensation curve is also deduced through numerical analysis. This research is expected to provide a theoretical guide for distortion compensation of the crossbeam.

In order to make a 5-axis linkage horizontal machining center have better dynamic characteristics, considering the influence of joint surface, dynamic characteristic analysis is conducted to the machining tool. Based on finite element modal analysis results, the weak link is found and optimized. Through the finite element calculation and analysis, the structure rigidity obviously raises after optimization. This offers a new idea on how to improve the rigidity of complete machine of machining tool for later research.

The Relationship

This paper introduces the structure and working principle of planar flexible bending joint .It uses compressed air to drive the deformation, which can realize elongation and bending. On the basis of force and torque balance analysis, the relationship between the elongation and bending angle of joint and the air pressure are acquired. Experimental system is constructed on the static experimental device. Due to the errors of manufacture technology, the correction coefficient is introduced. The statics model can better reflect the process of movement after introducing a correction factor.

In order to improve the machining accuracy of the precision surface grinding machine, a 3-DOF micropositioning table is used as an auxiliary table to form the dual infeed system with nanometer level positioning accuracy. This paper mainly deals with the static characteristics of the micropositioning table. The direct and inverse kinematic models are obtained under different orientation descriptions, and the inherent relationship between different orientation descriptions is investigated. By use of Eular angle description, the reachable orientation space of the micro-positioning table is obtained. The theoretical static stiffness on the top surface of the table is also given, and the experimental tests are carried out to verify the established models.
