Pagination or Media Count:
This report describes an open architecture framework for advanced manufacturing controllers including machine tools, robotics, process control, and coordinate measurement. The methodology described is applicable to both system design as well as system retrofit applications. A component-based approach is used that allows system architectures to be developed from generic building blocks that address system requirements and resulting functionality requirements. Initial architectures are used to produce an application architecture that addresses specific system messaging requirement. An application system is then synthesized using off-the-shelf, reusableimplementation components for the application software. Hardwaresoftware specific platform issues are addressed through the use of system profiles, a convention adopted form the IEEE Portable Operating system Interface POSIX standard that is now gaining wide acceptance. A number of examples are provided demonstrating use of all aspects of the methodology on a typical machine tool controller application. Appendices provide details with respect to specific components, requirements, and domain models.
