    Research output: Book/ReportBookResearchpeer-review


    The research presented in this dissertation concerns the identification of problems and provision of solutions for increasing the degree of interoperability between CAD, CACSD (Computer Aided Control Systems Design) and CAR (Computer Aided Robotics) in Computer Integrated Manufacturing and Engineering (CIME). This research can be categorized into the following topics:· The recognition of the needs for information exchange as a means for integration of computer based information processing systems used in manufacturing and engineering.· The identification and use of the open systems' integration strategy based upon neutral interfaces as a proper integration strategy for information interchange between the computer based information processing systems in CIME.· The study and selection of ISO 10303-STEP as a proper standardized methodology for development and implementation of neutral interfaces· The development of a STEP based interface for general control system data and functions, especially related to robot motion control for interoperability of CAD, CACSD, and CAR systems for the extension of the inter-system communication capabilities beyond the stage achieved up to now.This interface development comprehends the following work:· The definition of the concepts of 'information' and 'information model', and the selection of a proper information modeling methodology within the STEP methodologies.· The elaboration of a general function model of a generic robot motion controller in IDEF0 for interface identification.· The provision of means for modeling of functional behavior in EXPRESS, and elaboration of a general information models of a generic robot motion controller in EXPRESS for interface specification.· The elaboration of schema-driven pre- and post processors in C++ for interface implementation by use of STEP based CASE tools.· Processor test and verification by test case studies.
