System integration for kinematic data exchange

Abstract

Industry needs a system neutral solution for exchange of kinematic models. In this article, the first known valid implementation of kinematic mechanisms based on ISO 10303 Standard for the Exchange of Product (STEP) is presented. The result includes an implementation framework and two developed prototypes. Two major challenges of standard-based development are identified and generalised: data integration and system integration, which are solved by the framework. The two prototypes are implemented to establish kinematic data exchange between Siemens NX® and STEP-NC Machine^TM via STEP AP214 files. Experiences of design and development of the applications are presented, and a validated case study of data exchange using the developed applications is shown. There are other attempts of using STEP as basis for modelling, but as the first valid STEP implementation on kinematics, this approach demonstrates the feasibility of pure STEP-based data exchange for kinematic mechanisms. The prototypes also show potential of utilising the framework for general standard implementations. The research is expected to motivate deeper understanding and extensive applications of the STEP standard in industry and academia.
