In order to adapt to the market that has undergone fundamental changes, the manufacturing industry is vigorously developing products with higher added value. In product development, the role of measurement technology is becoming increasingly important. At present, in the field of precision measurement and detection, the measurement accuracy has been developed from the original micron level to the nanometer level, and the detection of more finely processed shapes has received more attention. Not only the higher quality of the product such as shape size, surface roughness, roundness, etc., but also the various inspection techniques used to verify the accuracy of the machine tool itself are constantly improving.
Quality management needs for measurement technology
The pursuit of improving the processing efficiency and reducing the processing cost in the production workshop is endless. However, the most important thing is to improve product quality. Therefore, it is essential to adopt strict standards and implement thorough quality management.
As a means of quality management, it is necessary to construct a production line into a "self-discipline" system, such as using a high-precision component group to form a machine tool and a high-precision measuring machine on a production line. It can be predicted that the demand for testing equipment and support systems for quality management will further increase in the future.
In fact, at the production site, the use of gauges to detect products is still the mainstream detection method. Gauge is a special gauge that is customized for various products. It does not have the versatility of being used for other parts. If the design of parts is changed, it is necessary to redesign and manufacture the gauge. As the market diversifies its product requirements, the variety of parts and components continues to increase, and the number of gauges increases. In addition, the production of high-precision gauges requires a high level of skill. With the replacement of skilled workers, it is now difficult to purchase high-precision gauges.
The test result obtained by the gauge is only whether the part is qualified or not, and whether it can enter the next process, and the actual size value of the part cannot be measured and recorded. Therefore, measuring instruments that can be used in production sites have received much attention. By introducing on-site measuring instruments, measurement data can be acquired and accumulated, and these data feedbacks can be applied to the processing flow. In addition, by establishing a database, recording and storing measurement data, when problems occur in the quality of defects after the parts are sold as final products, it is possible to know when and where the parts are processed, that is, traceable ( Traceability), it is easy to find the cause and solve the problem. On the other hand, with the improvement of the measurement accuracy of the on-site measuring instrument, higher requirements are placed on the environmental adaptability, reliability and detection efficiency of the instrument.
