Valve Body Three-Dimensional Parameterization Drawing & Casting Technology CAD System

This subject is a try of Valve body special-purpose casting technology CAD system. It make use of three-dimensional CAD parameterization designing technique to design and draw valve body mainly, and offer the database administration module of project, for finishing valve body casting technological design. Three-dimensional parameterization drawing is a kind important way of CAD secondary development. For engineering goods with form regular but with different design parameter, utilizing the parameterized drawing technology make application program, it is only need to change drawing parameter and can realize the drawing's automatic drawings. It is not only convenient and swift, but also can improve the precision of drawing; and it can solve the problems that three-dimensional entity products design cycle of tradition long and design efficiency low. Thus, it can improve the speed of designing greatly, reduce and work repeatedly, satisfy the request for the modern manufacturing system flexible, fast, improve the competitive power of market of the enterprise. The database administration module of project has offered the friendly man-machine interaction interface, make the designer able to concentrate energy on carrying on the effective creative design, so can finish designing & manufacture schemes better. The technological design of casting utilizes the computer and the data that the designer designed and storage in the database module, help to finish the technological design of casting. It can accelerate designing the process, improve the designing quality and efficiency, accelerate the updating of the products, improve the competitive power of the products. According to the development trend of the valve CAD, this subject set up valve body three-dimensional parameterization drawing & casting technology CAD system for some valve in commonly used. It includes some series of valve body products, such as angle stop valve, butterfly's valve and floodgate valve, etc. And it can carry on the fast serialization design and finish the technological design of casting to these valves of body, improve the efficiency of the designed capacity of the products and produced in casting greatly.This subject base on Windows 98/2000, Windows NT 4.0 operating system, utilize Access to set up the database, regard ObjectARX that the function is the strongest secondary development tool of AutoCAD as the development tool kit, regard Visual C++ 6.0 as compile tools, develop three-dimensional parameterization drawing & casting technology CAD software that based on AutoCAD 2000 platform. The representative of AutoCAD secondary development developing direction is ObjectARX, it is the first-selected developing tool that based on AutoCAD opened system structure's secondary development.
