Abstract
Research on spatial error modeling of the glass fillet machine is introduced based on the basic principles of multi-body system kinematics. Firstly, the topological structure and the low-order body arrays are described on the basis of the mechanical structure. Then, the spatial error analysis is carried out based on the theory of multi-body system. At the same time, the transformation matrix between the adjacent typical bodies is written. After that, in order to illustrate the relationship between the grinding wheel and the grinding point, the space error model of the glass fillet machine is established, which explains the effect of spatial structure on machining error and the calculation method of machining error. This model is easy to analyze the error and embodies the superiority on the error analysis and correction. Thus it provides a kind of ideal technique for the precision analysis of the glass fillet machine.
