Non-contact high efficiency is an important development direction of precision measurement technology

Experts predict that non-contact high efficiency is an important development direction of precision measurement technology.
In recent years, precision measurement technology has developed rapidly and achieved good results. For example, the online measurement technology can be used to display the processing status in real time and detect whether abnormal conditions occur in time, which can greatly improve the production efficiency. For machine tool control device, it requires high precision, low cost and miniaturization. Because the components such as automobile engines are required to have very high precision, in order to reduce noise, prevent environmental pollution and save energy consumption, these are the urgent requirements of The Times for the manufacturing industry.
In the process of high-precision machining and quality management, with the development of optomechanical integration and systematization, the optical measurement technology has developed rapidly, and the corresponding measuring machine products have emerged in large numbers, and the development of measuring software has been paid more and more attention.

In recent years, many non-contact measuring machines and various devices have been developed based on optical principles. For example, Mida Laser, the contactless tool measuring system of MARPOSS Company, is a new measuring machine using laser probe. This machine can automatically measure all tools without contact while the CNC machine keeps running, and can automatically position the tools according to the measured values. SONY Precision Engineering’s contact-free shape measuring machine YP20/21 is also a shape measuring machine that uses high-speed and high-precision autofocusing sensors with semiconductor laser. All scales are standard components, and sensors and load stations are controlled by microcomputers, providing excellent operational performance and data processing functions. Zip250, a non-contact coordinate measuring system sold by YKT, is a new measuring machine with high rigidity, high speed and high precision. The load capacity of the machine is 25 kg, and the resolution of the scale (X, Y, Z axis) is 0.25 micron. The machine is equipped with a CCD camera with digital flanges and the latest DSP processor, so that high-speed image processing measurements can be made. At the same time, it can also be used with a contact probe for related measurements.
With the emergence of non-contact, high-efficiency measuring machines, experts predict that the development direction of measurement technology in the 21st century is roughly as follows:
(1) The measurement accuracy is developed from micron level to nano level, further improving the measurement resolution;
(2) Transition from point measurement to surface measurement to improve the overall measurement accuracy (i.e. from the precise measurement of length to the precise measurement of shape);
(3) With the application of new technologies such as image processing, remote sensing technology will be popularized in precision measurement engineering;
(4) With the establishment of standardization system and the numeralization of measurement uncertainty, the reliability of measurement will be effectively improved.
In short, the measurement technology must achieve high precision, but also requires to achieve high speed and high efficiency, therefore, non-contact measurement and high efficiency measurement is bound to become the important development direction of precision measurement technology in the new century.
