Embodiment

[0064] Attached below Figure 1-19 The implementation steps of the present invention are described in detail.

[0065] Sequential modeling method of 3D machining process model based on feature removal recognition. This method first classifies and defines the feature removal; secondly identifies the feature removal based on the classification; finally completes the process model based on the result of feature removal recognition modeling. The specific technical route is as follows:

[0066] 1) Classification and definition of removal features

[0067] The removal features are divided into six categories, namely: boundary features, inset features, through features, thread features, ring features and other features.

[0068] (1) Boundary features

[0069] Refers to the shape on the boundary that is directly removed from the process model and intersects at least two or more blank surfaces, such as figure 1 Medium Feature F10.

[0070] (2) Inset features

[0071] Refers to t...

Abstract

The invention relates to a three-dimensional mechanical in-process model sequential modeling method based on removal feature recognition, which mainly aims to solve the technical problems of repetitive work and big application limitation in the prior art. In the method, first of all, the removal features are classified into boundary feature, inset feature, communication feature, thread feature and loop feature. On the basis of the classification, the method includes the steps of: 1) producing a workblank; 2) judging whether a next process is necessary, and if yes, entering the third step; 3) recognizing the removal features in the process, which includes selecting a feature type and recognizing the feature; and 4) modeling the in-process models. All the in-process models are assembled to form a whole process model and are organized by a standard structure of a process all-information model. The method makes full use of the geometrical characteristics of the original components, solves the problem of high quality requirement to the original component model design in three dimensional process design, speedily creates the in-process models according to the practical mechanical processing sequence and improves the overall efficiency of the process design system.

Description

technical field [0001] The invention relates to a sequential modeling method of machining process models based on feature removal recognition, that is, in the process of machining process design, a certain feature is removed (cut off) from the three-dimensional model of the previous process to create the model of the subsequent process 3D model, the 3D model of the first process is the blank model, and the 3D model of the last process is the final part model. The creation process of the three-dimensional model of all processes is consistent with the process of parts being cut step by step in actual processing, that is, the method of sequential modeling. It belongs to the technical field of mechanical processing. Background technique [0002] In the past ten years, my country's machinery manufacturing industry has made great achievements in computer-aided technology in product design and management operations. It has fully realized full three-dimensional product design, and ...
