【摘要】：在MBD技術(shù)的實施過程中，三維工藝是其重點和關(guān)鍵，也是企業(yè)在生產(chǎn)和制造水平上的具體表現(xiàn)。MBD工藝信息模型作為三維工藝的承載體，研究它的建模過程與工藝性評價，有助于在設(shè)計的早期階段對產(chǎn)品的工藝進(jìn)行分析，減少工藝設(shè)計人員的重復(fù)性勞動，節(jié)省研發(fā)的時間和生產(chǎn)成本，并使得模型能直接用于指導(dǎo)加工實際。MBD工藝信息模型作為產(chǎn)品信息的唯一載體與依據(jù)，保證了信息在傳遞過程中準(zhǔn)確性，加快產(chǎn)品的生產(chǎn)效率的同時，全面提升了產(chǎn)品質(zhì)量，滿足企業(yè)進(jìn)行信息積累和知識庫的擴(kuò)充的要求，提高企業(yè)在現(xiàn)代制造行業(yè)中的競爭力、適應(yīng)能力、生存能力。 本文以MBD工藝信息模型為研究對象，對模型的定義、信息表達(dá)、建模方法以及工藝性評價進(jìn)行了研究和探討，并在SolidWorks環(huán)境下建立了銅套的MBD工藝信息模型，利用二次開發(fā)工具Visual Basic6.0對模型的工藝信息進(jìn)行提取與工藝性評價，驗證和支持了本文的觀點。 首先，論述了目前國內(nèi)和國外MBD技術(shù)發(fā)展使用情況以及MBD工藝信息模型的研究現(xiàn)狀，指出了現(xiàn)今對MBD工藝信息模型研究的不足之處。 其次，對MBD工藝信息模型的定義進(jìn)行了解析和補(bǔ)充，詳細(xì)論述了MBD工藝信息模型的基本構(gòu)成并以此為依據(jù)對工藝信息層次化三維表達(dá)進(jìn)行了探討，提出了一種MBD工藝信息的標(biāo)注方法。 再次，根據(jù)MBD工藝信息模型的工藝性評價的含義、依據(jù)與目標(biāo)，提出了MBD工藝信息模型的工藝性評價方案，并介紹了評價方案的技術(shù)基礎(chǔ)。 最后，，以一個銅套零件為例，建立了銅套的MBD工藝信息模型，并開發(fā)了一個小型MBD工藝信息模型的工藝性評價系統(tǒng)，針對這個銅套的MBD工藝信息模型，進(jìn)行了工藝性評價，論證了本文的觀點。
[Abstract]:In the process of implementation of MBD technology, 3-D process is the key point and key point, and it is also the concrete performance of enterprise in production and manufacture level. As the carrier of 3-D process, the modeling process and process evaluation of MBD process information model is studied, and its modeling process and process evaluation are studied. It helps to analyze the process of the product in the early stage of the design, reduces the repetitive labor of the process designer, and saves the time of research and development and the cost of production. MBD process information model can be used as the sole carrier and basis of product information, which ensures the accuracy of information transmission, speeds up the production efficiency, and improves the product quality in an all-round way. It can meet the requirements of information accumulation and knowledge base expansion, and improve the competitiveness, adaptability and survivability of enterprises in modern manufacturing industry. Taking the MBD process information model as the research object, the definition, information expression, modeling method and process evaluation of the model are studied and discussed, and the MBD process information model of copper sleeve is established under the environment of SolidWorks. The secondary development tool Visual Basic6.0 is used to extract and evaluate the process information of the model, which validates and supports the viewpoint of this paper. Firstly, the development and application of MBD technology at home and abroad as well as the research status of MBD process information model are discussed, and the shortcomings of MBD process information model research are pointed out. Secondly, the definition of MBD process information model is analyzed and supplemented, and the basic structure of MBD process information model is discussed in detail. Based on this, the three-dimensional hierarchical expression of process information is discussed. A method of labeling MBD process information is presented. Thirdly, according to the meaning of process evaluation of MBD process information model and the aim of MBD process information model, the process evaluation scheme of MBD process information model is put forward, and the technical basis of the evaluation scheme is introduced. Finally, taking a copper sleeve part as an example, the MBD process information model of the copper sleeve is established, and a small MBD process information model evaluation system is developed. The MBD process information model of the copper sleeve is evaluated. This paper demonstrates the point of view.
