Title:
GRINDING STONE UPPER SLIP DETECTION METHOD AND DEVICE
Document Type and Number:
Japanese Patent JP2023179328
Kind Code:
A
Abstract:
To provide a grinding stone upper slip detection method and device which can correctly detect the occurrence of upper slip of a grinding stone by using an AE signal being the vibration generated due to crushing of abrasive grains and a vitrified bond in grinding processing.SOLUTION: A grinding stone upper slip detection device comprises: a frequency analysis unit 50 which frequency-analyzes an AE signal SAE generated in the time of grinding to a grinding object material 12 from a grinding wheel 20; and an upper slip detection unit 56 which detects upper slip of the grinding wheel 20 on the basis of the magnitude of a periodical change amount synchronized with rotation of the grinding object material 12 of the signal intensity of a prescribed frequency band of the signal intensities of the frequency spectra that are frequency-analyzed by the frequency analysis unit 50. With this, the device can correctly detect the occurrence of upper slip of the grinding wheel 20 on the basis of the magnitude of the periodical change amount synchronized with rotation of the grinding object material 12 of the signal intensity SP of the prescribed frequency band obtained by frequency-analyzing the AE signal SAE.SELECTED DRAWING: Figure 1
