Dynamic Reconfigurable Machine Tool Controller Dynamic Reconfigurable Machine Tool Controller
The design strategy of using dynamic-link libraries (DLL) to form a mechanism device driver permits a mechanism to assume different operating configurations, depending on the number of axes and machine resolution. For example, the machine can perform as a material removal machine in one instant, and then, by loading a new device driver, act as a Coordinate Measuring Machine (CMM). This strategy is possible because RMAC is a software and networked-based control architecture. Both the CAD/CAM planning software and the real-time control software reside on the same PC. The CAM process plan can thus directly control the machine without need for process plan decomposition into the forms supported by the controller.
The architectural framework is explained in detail and the methodology for control software reconfiguration into a device driver is presented. For demonstration purposes two device drivers are implemented on a prototype machine to demonstrate feasibility and usefulness.
