摘要： A system, method, and apparatus are provided for prioritizing the measurements made on manufactured parts while maintaining specified part quality standards. According to the method, system and apparatus, the process used by the CMM is modified so that the number of measurements made is reduced in accordance with the results of the analysis provided herein. A CMM apparatus is modified in accordance with the analysis results. A method for part measurement prioritization in a measuring system and method includes describing a set of features to be measured on a plurality of substantially identical parts, separating the set of features into sensitive features and non-sensitive features, dividing the non-sensitive features into a plurality of groups, and prioritizing the part measurements to measure the sensitive features and provide alternating measurements of the non-sensitive features.

摘要： An improved cutting tooth configuration in which, unlike the conventional, straight line tool pattern with its constant tool rise, each tooth is incrementally advanced relative to the prior tooth by an amount that progressively decreases. This accounts for the variations in reaction force on the cutting teeth caused by workpiece deflections, so that the net thickness of material removed by each cutting tooth remains relatively constant. Instability and variation in the cutting force are thereby avoided, and tool wear is decreased.

摘要： Methods, systems, and computer program products for controlling production systems. Methods include monitoring actual performance of a production system that includes a plurality of machines. The actual performance of the production system is compared to a planned level of performance of the production system. One or more short-term production constraints in the production system are identified in response to the actual performance being more than a threshold value away from the planned level of performance. A corrective action for the production system is determined to mitigate one or more of the short-term production constraints. The corrective action is applied to the production system.

摘要： A system may be used to detect corrosion between a first metal and a second metal, where the second metal is positioned adjacent to the first metal. The system may include a processor electrically coupled to each of the first and the second metals and configured to monitor a complex impedance between the first metal and the second metal, where the complex impedance may include a real component and an imaginary component. The processor may compare the real component of the complex impedance to a first threshold, compare the imaginary component of the complex impedance to a second threshold, and indicate a likelihood of corrosion if at least one of the real and imaginary components are below their respective threshold.
