Problems solved by technology

[0004] The purpose of the present invention is to provide a construction method of a dynamic three-dimensional process model, which solves the problems that the current two-dimensional process design is out of touch with the three-dimensional design model, and the information expression of two-dimensional engineering drawings is not intuitive and difficult to manage. The three-dimensional model is directly used for guidance manufacturing

Embodiment 1

[0027] Such as figure 1 As shown, a method for constructing a dynamic three-dimensional process model needs to be implemented according to the following six steps:

[0028] Step 1. Read the design model and establish a process reference model; based on the Pro / E secondary development technology, realize the automatic generation of the design model to the process reference model;

[0029] Step 2, automatically calculate and generate the rough model, and automatically assemble at the same position as the process reference model; automatically calculate and generate the blank based on the process reference model to automatically calculate the maximum external dimension, provide standard blank raw materials, which are square or cylindrical, and produce The blank model, the whole process is automated through the secondary development technology of Pro / E; the automatic assembly of the blank model and the process reference model at the same position refers to the creation of a proces...

Embodiment 2

[0047] The steps of this embodiment are basically the same as those of Embodiment 1.

[0048] Such as image 3 As shown, the user runs this software in the Pro / E environment, enters the process reference model creation interface (the design model has been imported), and clicks the "Copy" button to copy a process reference model with the suffix "REF" from the design model ;Click the "Get" button to get the drive size information from the process reference model; click the "Median" button to automatically take the median value according to the upper and lower tolerances for the size selected in the interface; click the "Modify" button to save the size list Write the new size value in the model back to the model, and regenerate the reference model after the write is successful.

[0049] Figure 4 Create an interface for the process model. The user selects the blank type in the dialog box, and enters the corresponding allowance value. Taking a square workpiece as an example, the...

Abstract

The invention belongs to the field of the technological process of a three-dimensional design model, and relates to a method for building a dynamic three-dimensional process model, which is characterized in that the method for building the dynamic three-dimensional process model is carried out according to the following six steps of: reading the design model, and building a technological reference model; automatically calculating the produced blank model, and automatically assembling the produced blank model with the technological reference model at the same position; organizing and managing the technical schedule; dynamically creating processing the characteristic; correlating the technical schedule with the characteristics; and storing the processing information and the model. The method for building the dynamic three-dimensional process model solves the problem that the two-dimensional technological design and the three-dimensional technological design are disjoined at present, and a two-dimensional model is taken to directly guide production and manufacturing, the traditional mode of 'three-dimensional design plus two dimensional' is broken through, and accordingly, the technological design efficiency is obviously improved; and moreover, the manufacturing staff can directly obtain the machining features and the corresponding technological information on the basis of the three-dimensional technological design, so the preparation periods of production and manufacture are greatly shortened, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the field of three-dimensional process design, and relates to a method for dynamically generating a manufacturing process-oriented machining procedure model, in particular to a method for building a dynamic three-dimensional process model. Background technique [0002] With the rapid development and popularization of 3D CAD software, 3D CAD system has become the basic platform for digital design and manufacturing of enterprises. However, most of the current process design is carried out on the 2D engineering drawing of the part. The 3D model is only used as a reference. Only when the part is more complex or Only when the process regulations are complicated, process designers will refer to the 3D model for process design. Based on paper two-dimensional engineering drawings, craftsmen use two-dimensional CAPP system to complete process design and generate paper two-dimensional process cards. As a result, the data source is not un...
