Embodiment Construction

[0035] like figure 1 As shown, a three-dimensional model-based process information expression method, its specific implementation process includes the following three steps:

[0036] Step 1, construction of process information identification symbols; on the basis of some process information identification symbols given by domestic standards, designers dynamically define expression symbols through secondary development in the Pro / E environment, and use Oracle as the database to process information Template-based customization and expansion of identification symbols to construct process information identification symbols that meet the requirements of relevant standards;

[0037] Step 2, process information combination symbols are dynamically generated; according to the symbols constructed in step 1, the customized identification symbols are processed, various process information identification symbols are arranged in an orderly manner, and process information combination symbols...

Abstract

The invention relates to a technique information expressing method based on a three-dimensional model, which is characterized by comprising three following steps: constructing technique information identification symbols, dynamically generating technique information combination symbols, and carrying out three-dimensional technique information labeling. The technique information expressing method can realize the interlinking of technique information and three-dimensional technique information by the three-dimensional labeling, and unify the design and the technique on a three-dimensional platform so as to replace a two-dimensional paper technique card, thereby solving the problems that the two-dimensional technique information is non-intuitionistic in expression, various in forms, hard in management and the like in the prior art.

Description

technical field [0001] The invention belongs to the field of three-dimensional process design, and is a method for expressing standardized machining process information by using three-dimensional labeling technology, in particular, a method for expressing process information based on a three-dimensional model. Background technique [0002] Most of the current process design is carried out on the basis of 2D drawings. In addition to building 3D models, designers also need to spend a lot of time and energy on converting 3D models into 2D drawings; Design a 2D process card and submit it to the factory for use. Such frequent changes not only increase the workload, but also make it difficult to guarantee the uniqueness of data. There are problems such as inability to effectively use design model information, difficulty in data sharing, and confusion in design knowledge acquisition and management. These problems have gradually become the bottleneck of digital manufacturing. Under...
