Abstract
An accuracy diagnostic device for a machine tool diagnoses an accuracy of the machine tool. The machine tool includes a change amount detection unit that measures a change amount. The change amount changes due to an installation environment and an operational motion. The accuracy diagnostic device includes a change-amount-reference-value recording unit that records a reference value of the change amount. The accuracy diagnostic device obtains the change amount measured by the change amount detection unit. The accuracy diagnostic device diagnoses a change of the accuracy of the machine tool based on a first change index derived from a magnitude of a change of the change amount per a predetermined period and a second change index derived from the current change amount and the reference value.
