【摘要】 介绍了以AutoCAD为开发平台的地勘牙轮钻头专用CAD软件系统的开发及其应用。该系统由参数设计、布齿设计、参数化绘图 3部分组成 ,可采用菜单、对话框和图标等形式对地勘牙轮钻头进行计算机辅助设计。在参数选取后进行布齿设计 ,然后进行参数化绘图 ,分别绘制出牙掌图、牙轮图和其它零件图 ,最后绘制装配图更多还原

【Abstract】 The development and use of CAD system specifically for the geological drilling cone bit design with Auto CAD as its development platform is described. The system consists of three parts: parameter design, teeth arrangement design, and parametrical drawing, the computer aided design of geological cone bits can be performed by the use in menu, dialogue boxes and pictures. With the parameters selected, the teeth arrangement is designed, then the parametrical drawing is carried out to make the cone leg drawing, cone drawing and other parts’ drawing; and finally make the assembly drawing.更多还原
