Paper Abstract

In a recently awarded ARPA program to advance the state of the art of parallel actuated next-generation machine tools, a vertically integrated team led by Martin Marietta is applying recent advanced in electroceramic smart materials and advanced composites to achieve leapfrog advanced in precision, flexibility, and speed of machine tools. Specific approached to achieve these advanced include active vibration cancellation, improved control technology, and design optimization using advanced structural and dynamic models. In this program, the team will integrate large high-force actuators, composites, and active vibration control with the Ingersoll Milling Machine Company's innovative Octahedral Hexapod machine to develop to Advanced Reconfiguration Machine for Flexible Fabrication. The enhanced Octahedral Hexapod machine will provide new levels of machining flexibility while still retaining precision and low cost. This technology will have widespread impact on the flexible fabrication of materials--especially those that are tough to machine traditionally--in several industries, e.g., aerospace, defense, aircraft, and automotive.
