Research And Development Of Process Drawing Module Based On The Visio For CAPP System

With the development of computer-aided process planning (CAPP) system, mechanical industry pays more and more attention to integrated CAPP system, the current CAPP systems commonly draw diagrams by other drawing software , enterprise in the implementation of CAPP system takes a lot of time complete the process drawing, and completing a process schematic need to switch back and forth between CAD and CAPP system, it is very inconvenient, and prone to error .The method hampered the promotion and use of CAPP system in the enterprise, therefore, integrating the process diagram module into the CAPP system for integrated development of CAPP systems is significant.This thesis described interface design and mechanical engineering drawing of Microsoft visio 2003 in detail , and introduced some functions of microsoft visio 2003, especially the window of the mold. powerful functions of mold window is a great bright for microsoft visio 2003, the mold brings a great convenience to users.Development of the drawing tool is to solve the issues of convenient drawing process diagrams and information sharing. The user takes text, line, curve, arc, rectangle, ellipse and other graphic elements as base to build graphics components, and through the movement, combination, rotation, scaling, alignment, offset, label of graphics, draws process diagrams finally, and saves it to a database or saved as a graphics library.Based on the analysis of modular software development, to propose a dynamic link library (Dynamic Link Library) approach is more suitable for integrated development of CAPP process diagram. And to take Visio drawing control as the secondary development components, Visual C + +6.0 as development tools. A detailed analysis of the functional requirements of process diagram and the integrated approach between CAPP system and drawing tools and complete the basic functions of the process diagram. Drawing tool implements the graphics rendering, image editing, text annotation, graphic database and other functions.The drawing tool is specifically designed with simple and practical, user-friendly features, consistent with visual design. The system takes secondary development of Visio as a means, and has advanced technology, innovative ideas. Fully use of the functions from Visio greatly reduces the difficulty of development and reduces development costs and shortens the development cycle particularly in mechanical drawing.
