Abstract

See full text

Provided a vibration measurement device for a rotary tool held by a tool holder that is coupled with a spindle and axially rotates in cooperation with the spindle. The vibration measurement device includes: a pair of acceleration sensors attached to a horizontal plane with respect to a rotary axis of a rotary tool in a manner symmetric to the rotary axis; an amplifier circuit that matches impedance of acceleration information from the acceleration sensors and amplifies voltage; a low-pass filter that removes predetermined high frequencies from an output signal of the amplifier circuit; and a subtraction circuit and an addition circuit that output a parallel vibration signal in an XY direction and a vibration signal in a rotational direction, respectively, from the output signal of the low pass filter.
