Description

technical field [0001] The invention relates to an acoustic emission monitoring device, in particular to a grinding wheel grinding acoustic emission monitoring device. Background technique [0002] With the development of modern science and technology, high-performance optical surfaces of various specifications have been widely used in military and civilian fields, and the existing manufacturing level is difficult to meet the increasing demand in quality and quantity. Low-cost mass production of high-quality optical components has become an urgent problem in the optical manufacturing industry. [0003] Diamond grinding wheel grinding is the main processing method of optical components. Based on the dynamic signal feature extraction and recognition technology in the grinding wheel grinding process, online monitoring and control of the grinding state is an effective way to improve the efficiency of optical surface processing. During the grinding process, the damage and wear o...

AI Technical Summary

Problems solved by technology

The device is limited by cooling conditions and can only be used for wet grinding, and the collected signals will be interfered by the flow and pressure of coolant

At present, the research work also installs piezoelectric acoustic emission sensors around the grinding wheel for grinding acoustic emission monitoring. This method can collect acoustic emission signals with a high signal-to-noise ratio, but it needs to change the structure of the grinding wheel, which has poor versatility.
