Abstract

It is difficult to integrate the complete geometric errors into the three-dimensional (3D) solid model in the present computer-aided design (CAD) system, which leads to the fact that virtual assembly technology based on the ideal CAD model cannot predict the influence of geometric errors on the assembly quality. The construction of the realistic geometric solid model is one of the key technologies to promote the practical application of virtual assembly technology. The dimension information and the geometric errors information of the parts are all expressed in the CAD model through the proposed integration method. The realistic geometric solid model is expressed by boundary representation (B-rep), and is reconstructed based on SAT file. C language programming is used to achieve the above functions. This method realizes the underlying data integration between the ideal CAD model and the geometric errors surface model, and improves the credibility of virtual assembly.
