封面扉頁
摘要
本設計軟件是針對機械零件中標準件的參數化繪圖而編制的。內容主要包括套筒型聯軸器、凸圓型聯軸器、拉伸彈簧、壓縮彈簧、扭力彈簧等的標準件的參數化設計。本軟件是采用AutoCAD自帶的開發語言AutoLISP和對話框語言Visual Basic進行設計的,結合AutoCAD2004進行繪圖的。
程序的設計和編程的過程主要有:AutoCAD2004菜單文件的設計和編程;對話框的設計和編程;對話框驅動程序的編制和調試;標準件相關參數的查找、概括、復制及參數文件的編制;繪圖程序的編制和調試;程序總體調試、加載和試運行。本論文也以這些過程為總綱,比較詳細的闡述了本軟件的編制和使用過程,也對相關程序文件編制和設計的意義作了說明。讀者和用戶可以通過論文比較詳細的了解該軟件的全部編制和使用過程。
關鍵詞:參數化;AutoCAD;AutoLISP;標準件;繪圖
ABSTRACT
The software of this design is designed for drawing standard componentgraphics of machine-tools with argument. It is mainly included the argumentdrawing of the bearing, the screw, the nut, the washer, the bond and the pin.The software is designed with Auto LISP and Visual Basic of AutoCAD, and drawsgraphics with the drawing software with AutoCAD2004.
The design of the procedure and course worked out are: Design andworking out of AutoCAD2004 menu files; Design and debugging of the communicationframe; Establishment and debugging of the communication frame driver; Standardcomponent relevant parameter find out, briefly, person who shoulder andparameter establishment of files; Establishment and debugging of the mappingprogram; The procedure debugs, loads and test run overall. Thesis this regardthe course as super class too, explain copies of establishment and use thecourse of software in detail comparatively, Files work out and meaning thatdesign explain after making to relevant procedure too. The reader and user canbe through all worked out and use the coursing of this software ofunderstanding with more detailed thesis.
