Abstract

A dynamic characteristic calculation apparatus (100) for a machine tool calculates dynamic characteristic of the machine tool executing an interrupted machining by moving a rotational tool (6) relative to a workpiece (W). The apparatus (100) includes a detector (102) detecting acoustic wave generated by vibration of the rotational tool (6) or detecting magnetic property being variable by the vibration of the rotational tool (6) where said rotational tool (6) is excited to vibrate, and a calculation division (103) calculating a natural frequency f of the one or plural tool tips (6a, 6b) in a vibration system, in which the one or plural tool tips (6a, 6b) of said rotational tool (6) is a vibration body, on a basis of a value detected by the detector (102).
