NC (Numerical control) Tool breakage monitoring method for cutting system fault diagnosis

摘要

In order to detect the breakage of the tool during drilling and cutting, it is necessary to simultaneously measure and analyze the change of AE and the cutting force, and the breakage judging group satisfies both the sudden increase of AE and the abrupt decrease of cutting force, Is divided into drilling tool destruction hardware (1), turning tool destruction hardware (2), and software of each type. It is processed in real time process. In the hardware part, only noise is removed from the signal. And analyzed by the PC software, and the judgment command in the PC is converted into an analog signal and transmitted to the controller of the NC. A method of monitoring tool breakage for diagnosing an NC (Numerical control) cutting system fault.
