Title: VIBRATION STATE DETECTION DEVICE AND MACHINE TOOL INCLUDING VIBRATION STATE DETECTION DEVICE
Abstract:
The present invention provides a vibration state detection device 100 and a machine tool including the vibration state detection device 100, the vibration state detection device 100 being provided with: an image capturing device 130 which captures an image of at least one element to be driven which is driven by a driving device of the machine tool; and a vibration state analysis unit (110) which calculates a parameter corresponding to a vibration of the element to be driven, on the basis of image data for each prescribed time elapse acquired by the image capturing device 130, wherein the parameter includes at least a frequency. Accordingly, even if cutting oil or a chip, etc., is attached to a tool of the machine tool, the vibration state detection device can reliably obtain a parameter corresponding to a vibration caused by cutting, and thus, the vibration caused by cutting can be suppressed by including this vibration state detection device.
