摘要
本文采用计算机参数绘图方法。在Auto—CAD软件包的基础上,采用BASIC语言进行编程,来建立塑料模具标准零件图库。这样同一类型的零件在图库中只存一幅,用户需要这类图形时,只要键入相应的图形尺寸,计算机就可自动地按照所要求的图形尺寸比例将图形绘出,使图库中存图数量大幅度减少,用户使用方便,出图迅速,准确,比工厂现用的成组分类方法建库工作量要少的多。我们认为是建立标准零件图库的一种行之有效的方法。
This paper discusses the parameter drawing method by means of the computer. On the basis of the Auto-CAD drafting package, we use BASIC language programming to establish the graphics library of the standard spare parts of the plastics mould. When an user needs this type of graphs, he only needs to enter corresponding graphics size from the Keyboard. Then the computer will give the graphics of the needed size automatically and the graphics stored in the graphics library will be greatly decreased. It is easier to operate and the plot output is quicker and more accurate. We think it would be an effective method to use the parameter drawing to establish the graphics library of standard spare parts.
