Obiettivo The objective of this project was to apply CIM concepts to the heavy welded-fabrication industry, replacing the traditional "islands of automation" approach with an integrated approach which could be developed and exploited economically. The programme of work was as follows: -analysis of heavy fabrication manufacturing systems using Data and Functions Networking (DAFNE) methodology -design of a generalised CIM framework using DAFNE -development of selected production subsystems within the CIM framework, eg automated welding cells with CAD-simulation cell-instrumentation quality control linkages - study of computer-aided production management. The objective of this project was to apply computer integrated manufacture (CIM) concepts to the heavy welded fabrication industry, replacing the traditional islands of automation approach with an integrated approach which could be developed and exploited economically. The programme of work was as follows: analysis of heavy fabrication manufacturing systems using data and functions networking (DAFNE) methodology, design of a generalized CIM framework using DAFNE, development of selected production subsystems within the CIM framework (eg automated welding cells with computer aided design (CAD) simulation cell instrumentation quality control linkages) and study of computer aided production management.Arc welding cells were developed together with the links to the necessary subsystems. Quality inspection, instrumentation, databases, CAD, simulation and offline programming were defined and demonstrated. The organizational and production models of heavy fabrication were studied with the use of appropriate methodology tools (DAFNE), and a general reference model for the industry type was produced.Successful implementation of CIM architectural model, adapted to welding in heavy industry (eg shipbuilding), demonstrated the opportunites for considerable improvements in productivity and product quality and will help to make the industry more responsive to market needs. The 2 project demonstration cells made use of simulation and offline programming through the application of modular and structured techniques for generating welding torch trajectories.Weld cell performance was also monitored via a specially constructed data gathering and file system which had potential for real time intervention, including adaptive control of the weld production activities.Arc-welding cells were developed, together with the links to the necessary subsystems: quality inspection, instrumentation, databases, CAD, simulation and off-line programming were defined and demonstrated.
