Title:
VIBRATION SOURCE ESTIMATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2018/216260
Kind Code:
A1
Abstract:
A vibration source estimation apparatus (1) is provided with: a characteristic vibration frequency storage unit (10) that stores the characteristic vibration frequencies of constituent members that include a tool, a tool holder, a workpiece, and a main shaft, in which vibrations are caused by machining; a vibration detection unit (2) that detects vibrations and outputs signals thereof; a frequency analysis unit (4) that performs frequency analysis of vibration signals outputted from the vibration detection unit (2); a vibration source estimation unit (5) that estimates, as a vibration source, a constituent member having a characteristic vibration frequency closest to a vibration frequency on the basis of the vibration frequency analyzed by the frequency analysis unit (4), with reference to data stored in the characteristic vibration frequency storage unit (10); and a notification device (9, 15) that sends notification of information regarding the constituent member estimated as the vibration source by the vibration source estimation unit (5) to the outside.
