【摘要】：計(jì)算機(jī)輔助設(shè)計(jì)是機(jī)械行業(yè)快速持續(xù)發(fā)展的技術(shù)基礎(chǔ)和必要手段,在市場(chǎng)競(jìng)爭(zhēng)日趨激烈的今天,適合企業(yè)的專業(yè)CAD軟件在縮短設(shè)計(jì)周期、提高生產(chǎn)效率方面起到了至關(guān)重要的作用。傳統(tǒng)的機(jī)械設(shè)計(jì)在公差配合、幾何公差和表面結(jié)構(gòu)參數(shù)的選取及工程材料的選用等方面主要是依靠工程師的經(jīng)驗(yàn)和設(shè)計(jì)手冊(cè),但是對(duì)于缺乏經(jīng)驗(yàn)的工程師來(lái)說(shuō)無(wú)疑存在很大的困難,而且查閱手冊(cè)費(fèi)時(shí)易出錯(cuò)。所以,將專業(yè)的繪圖軟件AutoCAD開(kāi)發(fā)為兼繪圖與設(shè)計(jì)于一體的輔助設(shè)計(jì)軟件具有重要的實(shí)際應(yīng)用價(jià)值。 本文以AutoCAD 2010為開(kāi)發(fā)平臺(tái),利用其提供的Object ARX二次開(kāi)發(fā)工具,結(jié)合Access 2003數(shù)據(jù)庫(kù),依據(jù)最新推出的國(guó)家標(biāo)準(zhǔn),用Visual C++2008.NET開(kāi)發(fā)出一套機(jī)械設(shè)計(jì)輔助工具,應(yīng)用本系統(tǒng)可以顯著的提高設(shè)計(jì)效率。 首先對(duì)相關(guān)文獻(xiàn)和手冊(cè)進(jìn)行了研讀,把機(jī)械設(shè)計(jì)時(shí)需要用到的資料進(jìn)行分類整理,建立數(shù)據(jù)庫(kù)以備查詢；進(jìn)而對(duì)AutoCAD的開(kāi)發(fā)機(jī)制進(jìn)行研究,確定系統(tǒng)總體設(shè)計(jì)方案和各模塊的實(shí)現(xiàn)方法；最后用Visual C++2008.NET編程語(yǔ)言編程實(shí)現(xiàn),并結(jié)合MFC開(kāi)發(fā)出良好的人機(jī)交互界面。本文開(kāi)發(fā)的機(jī)械設(shè)計(jì)輔助系統(tǒng)包括五個(gè)模塊,分別為圖塊、序號(hào)及明細(xì)表模塊、公差配合模塊、幾何公差模塊、表面結(jié)構(gòu)模塊和常用工程材料模塊。公差配合模塊、幾何公差模塊和表面結(jié)構(gòu)模塊不僅可以實(shí)現(xiàn)符號(hào)的選用和標(biāo)注,而且還給出相關(guān)參數(shù)的推薦選擇。
[Abstract]:Computer-aided design (CAD) is the technical basis and necessary means for the rapid and sustainable development of mechanical industry. In today's increasingly competitive market, professional CAD software suitable for enterprises is shortening the design cycle. Improving production efficiency has played a vital role. The traditional mechanical design mainly depends on the engineer's experience and design manual in the aspects of tolerance fit, geometric tolerance and surface structure parameter selection and engineering material selection, etc. But there is no doubt that it is difficult for inexperienced engineers and that reading manuals is time-consuming and error-prone. Therefore, it has important practical application value to develop the professional drawing software AutoCAD as the assistant design software which combines drawing and design. This paper takes AutoCAD 2010 as the development platform, uses the Object ARX secondary development tool and the database of Access 2003, according to the latest national standard, develops a set of auxiliary tools of mechanical design with Visual C 2008.NET. The application of this system can significantly improve the design efficiency. First of all, the relevant documents and manuals are studied, the materials needed in mechanical design are classified and sorted out, and the database is set up for inquiry. Then, the development mechanism of AutoCAD is studied, and the overall design scheme of the system and the realization method of each module are determined. Finally, the programming language of Visual C 2008.NET is used to realize it, and a good man-machine interface is developed with MFC. The mechanical design assistant system developed in this paper consists of five modules: drawing block, serial number and detail list module, tolerance matching module, geometric tolerance module, surface structure module and common engineering material module. Tolerance matching module geometric tolerance module and surface structure module can not only realize the selection and marking of symbols but also give the recommended selection of related parameters.
