Abstract
A resource-sharing system enables multiple work areas to share an energy resource on a real-time, asynchronous basis in order to perform manufacturing processes. A specific embodiment involves a communication and control structure for a distributed laser processing system wherein the work areas, in communication with a cell controller via a cell-level LAN, share high-power lasers through beam multiplexers and optical fibers. The cell controller, typically in communication with a factory information system computer over a factory-level network, receives information relating to processes to be performed in the workareas, and makes this information available to the workareas as a node in the cell-level LAN. With such an arrangement, tools requiring the laser energy within the work areas may be controlled in real time by their associated station controllers, as cell controller need only be responsible for coordinating more global activities. The implementation of a digital switching network enables a particular work area to assume direct, real-time and asynchronous control of one of the laser resources in accordance with the requirements of a given materials processing application.
