Document Type and Number:
WIPO Patent Application WO/2018/119845
Kind Code:
A1
Abstract:
Disclosed are a state detection method and system (10) for a numerical control machine tool, wherein the method comprises: detecting a vibration signal generated by a numerical control machine tool during a working process; converting the vibration signal from a time domain to a frequency domain; and determining a working state of the numerical control machine tool according to frequency domain information about the vibration signal or according to a combination of frequency domain information and time domain information about the vibration signal. A working state of a numerical control machine tool is determined according to a vibration signal generated by the numerical control machine tool during a working process, a detection method can be achieved with an algorithm, the cost is low, and unified monitoring of the numerical control machine tool can be achieved.
