the proposed project consists of the design of anew machine tool controller that will marry Next Generation Controller (NGC) technology with an advanced RISC hardware platform. The resulting machine tool controller's computational power should be more than ten times greater than that of existing controllers, resulting in higher accuracy paths, better surface finish, and faster cycle times. The use of a Sun Sparc Station front end will leverage off the high market volumes and rapid performance increases being driven by other markets. It will also provide connectivity to a variety of networking products, simplifying factory integration. The new SPOX real-time operating system for the digital signal processors in the proposed controller will enhance the portability and scalability of NGC application software and will enable a large quantity of software written for other applications to be used on this controller. The proposed architecture will also use new motion control technology develop for robot controllers that implements advanced features such as adaptive control and multi-machine coordination. The proposed controller will also be able to be used in a wide variety of applications that extend beyond machine tools, such as robotic control, general motion control, and process control applications. Anticipated benefits/potential commercial applications - the computational power of the proposed controller enables trajectory generation at the same rate as control law execution, resulting in higher accuracy paths, better surface finish and faster cycle times. The controller's flexible, expandable, modular, open architecture enable continual module improvements to be developed by small entrepreneurial software companies (a unique U.S. strength).

The proposed project consists of the implementation and demonstration of a prototype machine tool controller utilizing a SPARC hardware platform and based on the NGC specification for an open system architecture standard (SOSAS). The demonstrations will show modularity, scalability, performance, and the benefit of open architecture. The use of the SPARC platform leverages off of the high market volumes and rapid increases in performance driven by other markets while providing a controller with greater computational power than exiting controllers. The resulting controller will have higher accuracy path control, better surface finish and faster cycle times. The controller will utilize advanced motion control technology that implements features such as adaptive control and multi-machine coordination. The spox real time operating system for the digital signal processor, which is proposed as an option for the controller, will enhance the probability and scalability of the lowest layers of the proposed system. The demonstration will be implemented on a multi-axis work center or a turning center. Several verbal and written commitments have been received for the demonstration machine tool. The controller can be used in a wide variety of applications including robot control. Anticipated

Benefits:
The computational power of the proposed controller enables trajectory generation at state-of-the-art rates, while retaining an open system architecture on which new sensing and control technology can be quickly and easily integrated. The controller's flexible, expandable, modular, open architecture enable continual module improvements to be developed by small entrepreneurial software companies (a unique U.S. strength.)
