90 since the last century, how to develop the shortest possible time high-quality, cost-effective, easy to user acceptance of new products have become the focus of market competition. It was predicted that the current manufacturing technology development objectives are: strengthening the innovative technologies with our own product development capabilities and manufacturing capacity, enhance inter- Cooperation Capacity, time to market, improve product quality and production efficiency, thus enhancing business responsiveness to market demand and comprehensive competitiveness. Therefore, the rapid development of advanced manufacturing technology, computer integrated manufacturing technology, following after, there was the concurrent engineering, lean manufacturing, intelligent manufacturing, agile manufacturing, rapid prototyping manufacturing. If the United States in 90 years to achieve the “three three”, that is the product life cycle of three years; trial period for three months; the design cycle for three weeks. The main trend of the future development of manufacturing industries to the precision, flexibility, intelligence, integration, globalization, networking, virtualization direction. Precision Measurement Technology should adapt to this development, it is the role of mechanical disciplines: for advanced manufacturing services, and undertake the important task of quality and technical assurance. First of all to improve product quality and to achieve the most important goal as the basic starting point, to sophisticated test through the whole process of manufacturing. Second Precision Measurement Technology should be beneficial to the improvement of production efficiency, at least not impede the production rate, the detection method to be able to adapt to the rapid development of production requirements, not only for the detection and testing, but can not affect the requirements of testing the effectiveness of production. On a more positive point of view, should be as precise test technique to ensure proper services and to promote the productive capacity. ? Root According to Requirements of the development of advanced manufacturing technology, precision testing technology in line with its own law of development, and continuing to expand the new measurement principle, test methods and information processing technology, the mechanical discipline, the following will be expected to develop. 1. Zero waste production in the measurement controlIn machinery manufacturing, quality assurance is the implementation of the ideal of zero waste manufacturing production, in the process of achieving this goal, precision tests and importance of the role of technology is self-evident. Parts of the processing quality, the overall assembly quality with processing equipment, test equipment and test the analysis of information processing, and therefore achieve zero waste production, from the perspective of precision test should consider the following issues:? (1) in the workpiece before a test machine. How fast and accurate inspection of processing equipment for school, receive state machine accuracy, which significantly reduce rework, rework or exclude is very useful. Of course, testing equipment here, including the study abroad has been done in this research and development. (2) the production process on the workpiece or other forms of online measurement of 100% inspection, which need to study for dynamic or quasi-dynamic test equipment, and even processing equipment can be integrated into the special test equipment, so that real-time test. According to the test continuously changing process parameters, additional adjustments to processing equipment or feedback control. From the precision of a corresponding theory to study the dynamic accuracy theory, including the dynamic accuracy of the comments and so on. (3) should study how to make full use of measurement information to achieve zero waste production. 100% Online through the full use of measurement data, to analyze the processing and distribution of measurement error in the dynamic characteristics of machining errors under both dynamic performance and accuracy of the sensor characteristics and product quality loss and tolerance requirements given zero-waste manufacturing The basic theoretical model. Full use of artificial neural networks, genetic algorithms and other mathematical methods of modern processing and quality prediction accuracy, so that the quality of advanced control. 2. Vision Testing A lot of non-contact test technology, is particularly worth mentioning is the vision testing technology. Visual theory and modern technology, not only to simulate the functions performed by the human eye, more importantly, it qualified for the completion of the human eye can not work, so the visual test technology as today’s latest technology, in electronics, optics and computer technology continues to mature and improve on the basis of a rapid development.
