Based on the analysis of the geometrical structure and motion characteristics of a machining center,a new method for kinematical simulation of the machining center is presented in this paper.Two new notions,called structure bintree with direction and structure motion characteristics matrix,are used as the theoretical basis of the method.The major advantage is that this method unitizes the geometrical structure information and the kinematical mode information of the machining center into one matrix,which facilitates the algorithm of kinematical simulation to deal with data.An example is presented to illustrate the application of our method in NC verification.
