The Research And Development Of Master Production Scheduling Under ERP Mode

In today's economic globalization, the market increasingly competitive era, new product development time can become fierce competition in the market a key factor to win. The traditional product design process of double counting, such as repeated heavy workload modeling have been troubled by the product development staff, a serious impact on product design quality and efficiency. This phenomenon is particularly the design of cam highlights.In view of the current mapping software to create a flat disc-shaped cam profile of the process cumbersome and difficult to create, design flat plate cam and the majority of the necessary multi-parameter model in the three-dimensional CAD Cam system is not visible the issue is not commercialization, the subject of the use of Pro / ENGINEER to provide secondary Development Kit -Pro/TOOLKIT, in Visual C + +6.0 integrated development environment, the combination of database management technology development in line with user needs a flat plate cam CAD system. The system can be entered by the user the basic parameters of the cam, the automatic generation of three-dimensional model of the cam and cam mechanism to preserve the basic parameters of development by the Access database. The system greatly enhanced the efficiency of product design and design quality. In this paper, the main research contents are as follows:1.The establishment of Cam Template Library: A feature-based parametric design methods, in Pro / ENGINEER environment to establish cam Template Library, for Pro / TOOLKIT application calls. A convex contour to create the new method. This method eliminates the manual calculation of convex contour of the cumbersome process of parametric equation in Pro / ENGINEER parametric equation based on the direct generation of convex contour.2. Pro /ENGINEER secondary development and interface technology research and application.3. Pro / ENGINEER interface with the Microsoft Access Technology: In the VisualC + +6.0 development environment, using ODBC as a data access interface and object-oriented database programming techniques, to create the basic parameters of the cam and the database library to add, modify, delete operation, the achievement of Pro / ENGINEER users of Microsoft Access database in order to concentrate on managing the various data cam. On this basis can be achieved concurrent engineering cam design.4. System programming and interface design: the use of VC + +6 .0 and Pro / TOOLKIT to prepare system interface development tools, applications, user interface development system, the preparation of Pro / TOOLKIT application source code.5. Three-dimensional solid model cam module automatically. User input in accordance with the basic parameters of the cam, retrieve the corresponding template library cam cam model three-dimensional model, generated automatically to meet the needs of users of three-dimensional solid model of the cam.6. Self-diagnosis of the basic parameters of cam modules: the user input parameters of the cam, the diagnostic module and gives a message, and ultimately allow users to determine consistent with the pressure angle and curvature radius of the requirements of the basic parameters of the cam.7. Study between the various modules of the communication technologies.
