The sensing technology of applying the acoustic emission sensor to the grinding wheel loading phenomenon

For the grinding machine tool, the loading effect is a common phenomenon causing grinding wheel wear. This phenomenon will also cause the deterioration of the grinding wheel cutting capability, requiring a large grinding force, and it will increase the vibration and temperature of the machine. Therefore, the identification of influences from the loading effect is an important subject in grinding machines. We can know the status of a machine for manufacturing grinding through its acoustic emission (AE) signal. We hope that it can eventually be applied to the grinding tool machine for the purpose of online monitoring, achieving an AE pre-alarm system for the loading effect, reducing machine manufacturing errors, and improving grinding machine precision.
