Embodiment Construction

[0024] The purpose of the present invention is to propose a method for quickly obtaining process information of parts. Taking creating a cuboid and obtaining its heat treatment information as an example, the basic steps of its implementation of fast search are as follows:

[0025] Step 1: A part designer logs in to the 3D modeling software, creates a rectangle with a length and width of 30mm and 20mm respectively, stretches the rectangle, and the value is 10mm, the modeling of the cuboid is completed, and the geometric information has been successfully added into the feature tree;

[0026] Step 2: A craftsman logs in to the 3D modeling software, opens the already modeled cuboid, and adds process information to the cuboid, for example, add "Quenching" under the "Heat Treatment" subnode in the "Part Information" node . Select the "Part Information" node, select "Add" in the feature tree information toolbar, and fill in "Heat Treatment: Quenching" in the sub-node that appears un...

Abstract

The invention relates to a method for quickly acquiring process information of a part. The method comprises the following steps of: designing the part by design staff and process staff through three-dimensional modeling software, adding geometric information, processing information and other information onto nodes of a feature tree of the part for storing different types of attribute information; simultaneously improving a template library by the process staff, performing detailed classification on the corresponding process information, detailing to each sub-node, then starting PDM (pulse density modulation) software, checking the part into a product data management system through corresponding intermediate software and simultaneously storing the process information of the part into a database of the information quick acquiring method so as to facilitate the extraction of the process information; and logging into a PDM system by manufacturing staff, entering a visual page, entering the part concerned by the manufacturing staff and selecting the node of the information concerned by the manufacturing staff so as to be capable of generating a three-dimensional process digital model and a process file of the part which only carries the information concerned by the manufacturing staff.

Description

technical field [0001] The invention relates to a method for quickly obtaining process information of parts, which relates to the fields of computer software and computer information visualization, and in particular is a method for a manufacturer to quickly obtain a process model and a process document containing only the process information required by him / herself. Background technique [0002] The development of an aircraft must go through five main links: product design, process design, tooling design, product manufacturing, and inspection and testing. In the product manufacturing link, the 3D process model is derived from the 3D design model. In the traditional design and manufacturing process, the method of product information definition is to use three-dimensional solid model to describe geometric shape information, and use two-dimensional drawings to define product size, tolerance and process information. The dual data sources of 3D models and 2D drawings make it diff...
