【Abstract】 A geologic exploration cone bit is a main tool for drilling rock in geologic and petroleum drilling. Its performance has an important effect on the drill hole quality, penetration, and drilling cost. However, it is difficult to detail the performance of a bit in the bottom hole because of the special structure of the bit, random lithology and complex phenomena experienced during drilling. Usually, a manufacturer designs and manufactures cone bits according to the users requirements. Because of the complex structures, every designed cone bit expenses mach time in drawing. The paramtrization drawing system for a geologic exploration cone bit is a specialized software system developed for secondary development using Auto CAD as its development platform and Auto LISP language for processing. Automatic drawing may be realized after the paramaters are input to the system. This system adopts from forms besides means, dialogs and icons. The users only need to learn the operation of Auto CAD. Being pointed out by dialogs, they can master and use the system freely. After using the system, the designer can save much time and improve efficiency. This paper introduces the development and application of the system.更多还原
