【摘要】：隨著PDM概念在國內企業(yè)的逐步深入,國產PDM系統(tǒng)也逐步成熟,市場也逐步壯大。在機械制造行業(yè)內,將企業(yè)已有的數字化模型有效地管理起來成為引進PDM系統(tǒng)后的首要任務。在管理數字化模型過程中,PDM系統(tǒng)經常會在模型導入電子倉庫后失去產品的層次結構,同時無法在二維CAD模型文件工作流程電子審批過后完成對應文件的電子簽批。因此,機械產品CAD模型的批量出入庫技術、二維CAD模型文件的工作流程電子審批技術是PDM系統(tǒng)有效管理企業(yè)數字化模型的重心,這兩部分被統(tǒng)稱為機械產品數字化模型管理技術。完成這項管理技術必須通過CAD與PDM系統(tǒng)的集成技術并借助CAD與PDM系統(tǒng)的二次開發(fā)技術才可以實現。本文借助校企合作項目研究的機會,對以SolidWorks為CAD系統(tǒng)、T5-PLM為PDM系統(tǒng)主要完成了以下內容:詳細討論了機械產品CAD模型屬性與層次結構信息的提取、分析與CAD文件對象存儲方法。采用頂裝配體遍歷法解決了產品結構信息與機械產品三維CAD模型一同出入庫的問題,完成了機械產品CAD模型的批量出入庫研究。借助XML技術解決了機械產品二維CAD模型文件在隨工作流程執(zhí)行中不能同時簽審的問題,給出了在審批流程回退時,二維CAD模型文件撤銷簽審的執(zhí)行方法。簡要介紹了SolidWorks二次開發(fā),對其二次開發(fā)代碼的閱讀與編寫方法進行了探究,并創(chuàng)新式地提出了若干種SolidWorks二次開發(fā)代碼的讀、寫方法。同時對所提出的方法進行了舉例佐證。根據機械產品數字化模型管理技術的研究,編寫出了若干個相關的PDM系統(tǒng)插件,解決了在校企合作項目中的問題,并為解決類似的問題提供了新的思路。
[Abstract]:With the gradual deepening of the concept of PDM in domestic enterprises, the domestic PDM system is also gradually mature, and the market is gradually growing. In the machinery manufacturing industry, the effective management of the existing digital model of the enterprise becomes the primary task after the introduction of the PDM system. In the process of managing digital models, PDM system often loses the product hierarchy after the model is imported into the electronic warehouse. At the same time, the electronic signature of the corresponding files can not be completed after the electronic approval of the two-dimensional CAD model file workflow. Therefore, the batch delivery and storage technology of mechanical CAD model, the working process of two-dimensional CAD model files, the electronic approval technology is the focus of PDM system to effectively manage the enterprise digital model. The two parts are collectively referred to as the digital management technology of mechanical products. The implementation of this management technology must be achieved through the integration of CAD and PDM systems and the two development techniques of CAD and PDM systems. With the help of research opportunities in school enterprise cooperation, this paper mainly completed the following contents for SolidWorks CAD system and T5-PLM PDM system. It discussed in detail the extraction and analysis of mechanical product CAD model attribute and hierarchy information, and CAD file object storage method. The problem of product structure information coming out with the 3D CAD model of mechanical products is solved by the top assembly method. The batch storage and delivery of CAD models of mechanical products is completed. With the help of XML technology, the problem that two dimensional CAD model files of mechanical products can not be signed at the same time can not be signed at the same time with the execution of work process. The implementation method of two dimensional CAD model files revocation and signature is given when the approval process is rolled back. This paper briefly introduces the two development of SolidWorks, explores the way of reading and compiling the secondary development code, and puts forward several ways to read and write SolidWorks's two development code innovatively. At the same time, the proposed method is illustrated with an example. According to the research on management technology of mechanical product digital model, we have compiled several related PDM system plug-ins, solved the problems in school enterprise cooperation projects, and provided new ideas for solving similar problems.
