基于MBD的三維CAD模型信息標(biāo)注研究
[Abstract]:Digital design is a key link in the field of mechanical design and manufacturing, and it is of great significance to the development of the whole mechanical manufacturing industry. With the development of MBD technology, more and more attention has been paid to 3D CAD annotation model. Especially, the application of MBD-based 3D CAD system has directly promoted the industrial age to enter a new field. In this paper, the method of information labeling and management for 3D CAD model of parts is studied, so as to complete the complete digital definition of parts. The research contents mainly include the following aspects: (1) The method of information labeling based on MBD on 3D CAD model using PMI (Product Manufacturing Information) function is studied. On the basis of this, a new method of PMI 3D marking based on UG/PMI function is proposed. (2) According to the latest national standard, a new method of surface roughness and geometric tolerance marking is designed. (3) A new method of effective organization and management of 3D CAD part model annotation information by "group" and "view" is proposed in this paper, which solves the problem of 3D part annotation caused by non-geometric information. The display effect is cluttered, which makes the information expression unclear and makes it difficult to identify the information in the machining process.
