A consortium of auto industry firms and two universities working as the Engineering and Manufacturing Alliance (EMA) has proposed the development of High Definition Metrology (HDM) technology that would enable factory floor machining tolerances within one micron (or two micron variation), better than a factor of ten improvement over the current state of the art. Breakthroughs in manufacturing technology tend to follow breakthroughs in measurement technology. The ability to build routinely to one-micron tolerances will enable high precision, accuracy and consistency in manufacturing not possible with present technology, and spark synergistic benefits to a wide range of U.S. industries, including aerospace, semiconductors, energy, and bio-medical engineering. The EMA members estimate that they will save more than $1 billion annually through the introduction of HDM processes. The proposed HDM technology is based on laser holography, and will require multi-disciplinary advances in holographic interferometry, laser optical system design, data processing, process modeling, and advanced manufacturing technology. EMA members include the Ford Motor Company (Dearborn, Mich.); the General Motors Corporation (Detroit, Mich.); the Chrysler Corporation (Auburn Hills, Mich.); Roush Enterprises, Inc. (Livonia, Mich.) and Coherix, Inc. (Ann Arbor, Mich.).
