封面扉页
摘要
本设计软件是针对机械零件中标准件的参数化绘图而编制的。内容主要包括套筒型联轴器、凸圆型联轴器、拉伸弹簧、压缩弹簧、扭力弹簧等的标准件的参数化设计。本软件是采用AutoCAD自带的开发语言AutoLISP和对话框语言Visual Basic进行设计的,结合AutoCAD2004进行绘图的。
程序的设计和编程的过程主要有:AutoCAD2004菜单文件的设计和编程;对话框的设计和编程;对话框驱动程序的编制和调试;标准件相关参数的查找、概括、复制及参数文件的编制;绘图程序的编制和调试;程序总体调试、加载和试运行。本论文也以这些过程为总纲,比较详细的阐述了本软件的编制和使用过程,也对相关程序文件编制和设计的意义作了说明。读者和用户可以通过论文比较详细的了解该软件的全部编制和使用过程。
关键词:参数化;AutoCAD;AutoLISP;标准件;绘图
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.
