Method and system for constructing process model on the basis of parameterization

Abstract

The invention discloses a method and a system for constructing a process model on the basis of parameterization. A parameterization design process model is constructed in advance; when a specific part is designed, the parameterization design process model associated with part design is inquired; the design dimension of an appointed processing part is set; according to the design dimension and relevant process knowledge in the parameterization design process model, the process dimension of the appointed processing part and corresponding process margin are obtained; and the obtained process dimension and the obtained corresponding process margin are used for carrying out instantiation on the parameterization design process model to generate a design model and revise corresponding process parameters, label information and process procedure information so as to finish the construction of the process model. The parameterization DPM (Design Process Model) which is generated in advance is called to construct an instancing model, the quick definition of a product and the quick generation of the process are realized, and product design efficiency is improved. Meanwhile, the process knowledge is combined into a product modeling process so as to be beneficial for the precipitation and the inheritance of enterprise knowledge.

Description

technical field [0001] The invention relates to the field of three-dimensional process design, in particular to a method and system for building a process model based on parameterization. Background technique [0002] With the development of enterprise informatization, the three-dimensional process collaborative expression technology gradually replaces the traditional two-dimensional drawing expression method. The 3D process builds the blank model based on the design model, and then adds process features according to the process to build the process model. The construction process features are constructed step by step according to the actual processing process, and the process is relatively complicated. [0003] At present, the typical process method based on feature recognition technology extracts design features by traversing the feature tree, maps the design features to process features, and then generates process rules through the process feature mapping process method,...

Problems solved by technology

This method is stable and practical. It is a traditional two-dimensional typical process method. It can only improve the process design efficiency to a certain extent. In the three-dimensional process, model borrowing cannot be realized.
