AI Technical Summary
Existing technologies cannot accurately monitor the surface morphology of workpieces during machining, especially under the influence of vibration between the tool and the workpiece, where traditional force sensors and acceleration sensors cannot obtain accurate data.
By receiving the sound pressure signal from the machining lathe, the sound pressure signal is decomposed and reconstructed using wavelet packet decomposition to obtain the high-frequency voltage divider signal, which is then mapped onto the workpiece surface model and converted into vibration displacement information to construct the three-dimensional surface morphology of the workpiece.
This technology enables real-time monitoring of the workpiece surface morphology during processing, avoiding the impact of vibration on signal acquisition, generating a visualized three-dimensional morphology, and ensuring the accuracy and real-time nature of the monitoring.
