Embodiment Construction

[0036] like figure 1 As shown, a sequential modeling method of machining process model based on feature removal recognition includes the following steps:

[0037] 1) Blank preparation: import the part model in the CAD system, and generate the blank model after successively passing the model verification, determining the process plan, editing the dimensional tolerance and determining the blank allowance;

[0038] 2) Process decision-making: determine the processing plan of the part process, machine tool selection, fixture selection, tool selection and cutting parameters;

[0039] 3) Process design: identify the features and define the processing features, then check the process model, form the process model, and process the process blank;

[0040] 4) Whether to proceed to the next process? If yes repeat steps 2 and 3, if no continue;

[0041] 5) Process publishing: output the process form and output process model, and then decide whether to convert it into a template, if yes...

Abstract

The invention relates to a machining process model sequential modeling method based on characteristic identification removal, which includes the steps: 1) blank preparation; 2) technological decision making; 3) process design; 4) judgment of whether one next process is proceeded or not, repeating of the step 2 and the step 3 if the next process is proceeded, and continuing if the next process is not proceeded; 5) technological release; and 6) visual manufacture. The method makes full use of geometric features of an original part model, solves the problem of design quality requirements of three-dimensional technological design on the original part model, and is capable of creating the process model according to the practical machining technological operation sequence, so that integral efficiency of a three-dimensional technological design system is improved.

Description

technical field [0001] The invention relates to a sequential modeling method of a machining process model based on feature removal recognition, that is, a three-dimensional sequential modeling method in which the creation of the process model is consistent with the actual machining process. 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 some parts have achieved virtual simulation verification, which guarantees production to a certain extent. smooth and smooth operation. However, based on the development of manufacturing technology at home and abroad, it can be found that the above-mentioned traditional CAPP work is based on two-dimensional drawings. At the same time, there are differences in time and space between process design and product design, and collabor...
