MANUFACTURING Sheffield Automation (formerly Giddings however, research in CMM technology continues within the manufacturing industry. Today, U.S. machine tool manufacturers provide CMMs for use on the factory floor, albeit without the high level of precision sought in this project. For example, Giddings & Lewis' Endeavor Series CMMs, which incorporate the partial successes of the ATP project, feature real-time temperature compensation in the range of +/-5° C, linear accuracy of up to 2 micrometers, and repeatability of 2 micrometers. This does not meet the proposal goals that intended to achieve "accuracy of straightness measurement" better than 0.5 micrometers and accuracy of angular deviation better than 0.05 arcsec. (Precision of angular deviation is not cited in current company literature.) However, factory-floor CMMs are currently available to assist the $500 billion U.S. discrete- parts industry in the cost-effective manufacturing of high- quality parts.
