Vibro_Energy Mill CAD System Analysis & Design Based On UML

Software scale and life period of mechanical CAD system continuously increases along with the development of production. It request better reusage, enlargement, maintenance. . . etc. Mechanical CAD system developed with structure method has bad readability, expansion and maintenance, development, Object-Oriented method provide a new software developing method. It' s a developing direction to use Object-Oriented method in mechanical CAD system.UML, a standard modeling language of Object-Oriented, amalgamates the basic concepts of usual Object-Oriented methods and unifies symbol system. It is significative to import UML to the developing of special mechanical CAD system and to research the application of UML in special mechanical CAD system. It will quick the developing of Object-Oriented CAD system, accelerate the application of Object-Oriented method in engineering software, promote the expansion and maintenance of software.This paper finished Vibro_Energy Mill(VEM) CAD System according to RUP developing process, with the base of the analysis&compare of structure method and usual Object-Oriented method , with UML as a modeling language, with the instruction of Object-Oriented thought. The method is offered to use UML in VEM CAD system developing. The usual process, realizing principle and realizing method of analyse&design VEM CAD with UML is given. The relation of VEM parts and assembles is analysed and expressed in computer. The attribute of VEM part object is specified with parametric method based on feature. The feature classes and part classes are defined. VEM system object model is persisted with relational and the method of mapping data model to relational database is specified. The system is realized with adoption of MFC VC, MS Access, Object ARX... etc. The realizing method of critical technicis offered and partial function of VEM CAD system is realized.New way of thinking that UML is applied in special mechanical CAD system develop is brought up and the process and concrete realizing method is specified through the research of applying UML in VEM CAD system develop. Common method of specifying the relation of part and assemble objects is put forwards. It' s more efficiency to organize and realize data using part parametric method to specify the attributes of part objects in comparison with common parametric technic. The Object-Oriented method based on UML is more available to enhance the expansion and maintenance compared with structure method and common Object-Oriented method.
