Embodiment Construction
[0016] The monitoring system provided by the present invention obtains the machine tool drive motor current signal and the machine tool tool processing information obtained from the numerical control system, goes through a series of signal processing and feature extraction selection processes, and finally monitors the tool wear amount to realize the monitoring of tool wear. Monitor VB, and feed back the monitoring results to the CNC system, and the CNC system responds accordingly according to the wear of the tool, prompting to change the tool or change the tool compensation amount.
[0017] like figure 1 As shown, the monitoring system includes data acquisition and judgment module 1, data processing module 2, feature extraction and selection module 3, fitting prediction trend curve module 4, tool wear rule module 5, tool wear compensation and tool change module 6, tool wear Learning module 7 and tool wear law learning library 8.
[0018] The tool wear law learning library 8 i...
