GUDA-6 REPRESENTING DESIGN INFORMATION OF GEAR DRIVES IN XML(GEAR UNIT DESIGN AND APPLICATIONS)

Abstract

Representation of design information is essentially needed in the collaborative design on the distributed design environment. In this paper, a methodology how to share the design information of a gear drive design using Extensible Markup Language (XML) is proposed. XML is the standard web language of the next generation and can be used as a neutral format shared by various design applications. Since XML is a platform-independent meta-markup language, it is possible that standardization of technical terminologies and reduction of additional programming efforts between web based design applications in the collaborative design. To show this advantages, we developed a gear drive XML application that will be used in the collaborative design of gear drives in web environment. This gear drive XML application is a markup-language that can represent the design information of machine elements (gears, shafts, keys and bearings) composing gear drives. Data Type Definition (DTD) for gear drives is also developed. The XML DTD for the gear drive design is divided into structure and semantics. The DTD structure is composed of dimensional information, material information and so on. For the DTD semantics, dimensional design terminologies are made according to the International Organization for Standardization (ISO) standards.
