In the field of gear measurement where the shape accuracy is critical, the measuring machine such as the NC tooth profile measuring machine of Osaka Seiki can automatically and quickly measure the parameters such as tooth profile, tooth direction and pitch of the gear, and can be eliminated. Direct transmission servo system for vibration effects. In the field of automobile manufacturing, how to improve the power transmission efficiency of gears has become a key technology, and therefore it is required to continuously improve the accuracy of the gear measuring machine. In order to improve the acceleration performance and comfort of the car, it is very important to eliminate the noise and vibration of the engine and the gearbox, especially the gearbox, which requires high detection accuracy of the gear. Regarding the measurement method of the gear, Osaka Seiki believes that "there is no national certification in Japan. Therefore, it is necessary to use the standard gear as the calibration standard to confirm the measurement accuracy, and then commission a foreign certification body to conduct the test." Demand for high precision, high resolution measurements As a positional accuracy measuring device, the common traceability system of Linear Encoder has not been established in Japan. In 2004, Heidenhain introduced a length accuracy tester at its Nagoya plant. This is the first precision calibration device developed by the German Institute of Physics and Technology (PTB). In terms of length measurement, the PTB is based on a laser, a reference scale, and a linear encoder with traceability, and the measurement accuracy is ensured in stages by a total of more than 10 length standards. For the measurement elements such as temperature, air pressure, and angle other than the length, a traceability system that performs accuracy verification for a period of six months to several years is also established. In recent years, along with indexing scale encoders, absolute (Absolute) encoders have gradually become mainstream. Heidenhain's encoders have achieved high precision, high resolution (up to 10 nm) and high speed communication. Digital Gauges for measuring dimensional accuracy require high precision, high resolution and adaptability to a variety of work environments. Sony Manufacturing Systems' new portfolio of digital metrology products has added a new model with smaller size, higher accuracy and lower resolution (up to 0.1μm) for high-precision measurement with a maximum range of 12mm. In addition, in order to meet the needs of users for flexible multi-point measurement and multi-interface output, the company also introduced MG series measurement modules that can flexibly respond to multiple interface lines (up to 64 lines) with multiple interface outputs. The company has passed the ISO 9001 international standard certification in order to build a quality assurance system that can obtain metrological regulations, meet customer needs, and has a traceability length verification system. Committed to providing total measurement solutions When measuring with a coordinate measuring machine, in order to ensure the traceability of dimensional accuracy and apply it to the inspection of the workpiece size, it is necessary to evaluate the uncertainty of the measurement. To this end, various error factors need to be evaluated to calculate the uncertainty. In the ISO/TC213/WG10 (coordinate measuring machine) standardization work, the accuracy evaluation standard of the coordinate measuring machine has been set, and the evaluation standard of the uncertainty is being explored. There has been competition in further shortening the measurement time of the coordinate measuring machine and increasing its speed of movement. At present, the technical bottleneck for further increasing the speed of measuring machine movement and rapid acceleration and deceleration is vibration. By adopting new probe technology, driving method and high rigidity design, vibration can be effectively eliminated, making it possible to further increase the speed of the measuring machine. Especially when the coordinate measuring machine is used for on-line inspection, it is required to compensate and correct the temperature error of the workpiece on the machining line. As a result, measurement equipment manufacturers are working to provide users with an overall solution to the measurement problems in processing. For the CMM, there is currently no precision measuring instrument that can be called a “reference gaugeâ€. The use of the gauge block can verify the accuracy of one axis and two axes, but it is still lacking to verify the triaxial accuracy as a characteristic of the CMM. The 3D Accuracy Verification Specification Quality Master developed by Shallow Marsh Technology is placed on the measuring table of the CMM and measured three times in the forward and reverse positions. The geometric accuracy of the CMM can be evaluated and easily corrected based on the measured data.
