【摘要】：特征技術(shù)在實現(xiàn)產(chǎn)品設(shè)計制造一體化的過程中起到關(guān)鍵的作用。一方面,特征模型能夠包含多種信息,可將與產(chǎn)品設(shè)計制造相關(guān)的各個環(huán)節(jié)有機的聯(lián)系在一起；另一方面,合理有效利用特征模型對產(chǎn)品進(jìn)行描述,可縮短產(chǎn)品開發(fā)周期,提高企業(yè)的設(shè)計生產(chǎn)效率。研究基于加工特征的零件設(shè)計方法,目的在于通過建立具有信息集成性與共享性的加工特征模型,將設(shè)計與制造并行結(jié)合,為產(chǎn)品的結(jié)構(gòu)設(shè)計與工藝生成兩者并行協(xié)同工作提供有效支持。在此背景下,本文主要從以下幾個方面做了具體研究。 給出了加工特征的定義,并對其進(jìn)行了分類,在此基礎(chǔ)上對加工特征所包含的信息進(jìn)行了分析與歸納,建立了加工特征模型,給出了加工特征模型重要信息的處理方法。采用配置文件技術(shù)存儲加工特征信息,為建立應(yīng)用系統(tǒng)提供信息支持。建立了制造資源模型,并給出了制造資源對加工特征的約束檢查方法,由此保證零件設(shè)計的可制造性。 從零件的制造過程出發(fā),研究了加工特征之間的組合關(guān)系,對特征組合關(guān)系進(jìn)行了分類,并給出了不同特征組合類型的判定方法,以及組合信息在特征文件中的描述方法,建立了針對不同組合關(guān)系的特征加工順序確定規(guī)則,為零件加工工藝生成提供了信息基礎(chǔ)和決策依據(jù)。 分析了零件加工特征域中切削成形信息和幾何特征域中幾何形狀信息的不同表現(xiàn)形式,以及信息之間的內(nèi)在聯(lián)系,以此為基礎(chǔ)建立了加工特征向幾何特征的信息映射機制,并構(gòu)建了特征映射規(guī)則和知識庫,采用基于知識和規(guī)則的方法實現(xiàn)了加工特征向幾何特征的映射。 通過UG NX 4.0軟件的行二次開發(fā),建立系統(tǒng)各功能模塊,在此基礎(chǔ)上構(gòu)建了基于加工特征的零件設(shè)計軟件系統(tǒng)。以某型號減速器為設(shè)計對象應(yīng)用系統(tǒng)進(jìn)行實例運行,運行結(jié)果表明了此系統(tǒng)能夠有效實現(xiàn)產(chǎn)品設(shè)計與制造的并行集成,提高了產(chǎn)品的設(shè)計研發(fā)效率,同時表明了該方法的有效性和可行性。
[Abstract]:Feature technology plays a key role in the process of product design and manufacturing integration. On the one hand, the feature model can contain many kinds of information, which can link all the links related to product design and manufacture organically. On the other hand, the product development cycle can be shortened by using the feature model to describe the product reasonably and effectively. Improve the design and production efficiency of enterprises. Part design method based on machining features is studied in this paper. The purpose of this paper is to combine design and manufacturing by building a machining feature model with information integration and sharing. It provides effective support for the parallel and cooperative work of product structure design and process generation. In this context, this paper mainly from the following aspects of specific research. The definition and classification of machining features are given. On the basis of this, the information contained in machining features is analyzed and summarized, a machining feature model is established, and the processing methods of important information of machining feature models are given. The profile technology is used to store the processing feature information, which provides information support for the establishment of application system. The manufacturing resource model is established, and the constraint checking method of manufacturing resource to machining feature is given to ensure the manufacturability of part design. Based on the manufacturing process of parts, this paper studies the combination relation among machining features, classifies the feature combination relation, and gives the methods of judging different feature combination types and describing the combination information in the feature file. The rules for determining the processing sequence of different combination relationships are established, which provide the information basis and decision basis for the production of parts processing process. Based on the analysis of different forms and internal relations of cutting forming information in machining feature domain and geometric shape information in geometric feature domain, the information mapping mechanism from machining feature to geometric feature is established. The rules and knowledge base of feature mapping are constructed, and the mapping of machining features to geometric features is realized by using the method of knowledge and rule. Through the secondary development of UG NX 4.0 software, the functional modules of the system are established, and the part design software system based on machining features is constructed. Taking a certain type of reducer as the design object application system, the running results show that the system can effectively realize the parallel integration of product design and manufacture, and improve the efficiency of product design and research and development. At the same time, the effectiveness and feasibility of the method are demonstrated.
