On Generation of the Specification Model for Concentricity Based on Mathematical Modeling
Feature specifications are important composite parts in the new generation of geometrical product specifications and verification (GPS). According to the theories of specification model of shaft parts, this paper presents a method to generation of specification model of concentricity. Firstly, the mathematical model of concentricity is established in terms of nominal geometrical features of product for the parts the functional requirement are satisfied. Secondly, the simulation points of the model are generated by using the methods of axial stratification and circumferential multi-angles. The concentricity specification model could be generated after these operations of association and collection. Finally, an example is applied to illustrate the new method. The experiment results show the effectiveness of the proposed method.
