Feed axis control method for machine tool and feed axis control device

摘要

In the control device (100) of the feed shaft (11) of the machine tool (200), an acceleration detector (20) for detecting the vibration acceleration of the tip of the machine tool and frequency analysis of the vibration acceleration to calculate the center frequency of the vibration The vibration analysis unit (30) to be identified and a band pass filter (40) for passing the vibration acceleration of the frequency set based on the center frequency, and the vibration acceleration of the frequency set in the band pass filter is servo amplifier ( It was made to give feedback to 9).
