| Research Abstract |
(1) Development of CAM system for plate parts.
A CAM system has been developed to generate NC data for drilling and reaming processes of the plates of the injection molds and the die-casting dies, based on the input information about the CAD data of the plates given in the IGES and/or DXF formats. The machining technology data for the drilling and the reaming processes are investigated and stored in the machining technology database. The database gives the relationships between the geometric and technological information about the holes to be machined and the machining information about the machining processes, such as the tools, the cutting conditions and the cutter location data.
(2) Development of distributed scheduling system for HMS
An object-oriented modeling technique is adopted to represent the holonic components of the manufacturing systems including workpieces and manufacturing resources. An object-oriented simulation system is developed to represent and to simulate real-time scheduling processes in the holonic manufacturing system. A set of simulation is carried our to verify the decision rules for the real-time scheduling from the viewpoint of the total make-span and the adaptability to the failure of the manufacturing resources.
(3) Verifications of the developed system.
The systems developed in the research have been verified from the viewpoint of both the process planning and scheduling in the holonic manufacturing systems
