The grid of bolt-node is a kind of new and modem architectural structure. It having widely been used in many industry and civil architecture because of such advantages as the simplification to install, the stable and firm structure to have and the convenience to carry out the special-shaped structure and so on. The bolt-ball is the core part of the grid structure of bolt-node. As the node, the bolt-ball is principally used to transmit the three-dimensional forces in the grid structure. So its machining accuracy and quality have direct impact not only on the installment quality of the execution of grid works but also on the distribution of the forces in the grid structure. Aimed at the concrete NC machining process of the bolt-node ball fixed on the specific dividing and clamping equipment, especially the problem of clamping which emerges from the manufacture, this text describes the whole procedure in details from the establishment of the rule to distinguish the state of clamping, discerning and getting the clamping information out of the machining process, until to the accomplishment of the clamping judgment of the machining path and II 12 m~ optimizing the time used in the manufacture of the bolt-node ball. Moreover, it also provides a virtual example of calculation by programming with the C language. This text focuses on providing the overall thought to work out the solution about the clamping problem of the bolt-node ball in the course of its CN manufacture, also gives consideration to two or more things about some details. I hope they are helpful to others in relevant researches.
