Abstract
An accuracy analysis system for a machine tool includes: a control unit, a data server, a data communication unit, a data analyzer, a corrected machine accuracy calculation unit, and a data display unit. The control unit stores preliminarily obtained accuracy data regarding a machine accuracy, compensation data for compensating for an error, and machine information. The data communication unit transmits the accuracy data, the compensation data, and the machine information to the data server. The data analyzer uses the accuracy data and the compensation data in the data server to obtain a compensation data correction value as a correction value of the compensation data and expected accuracy data when the compensation data correction value is applied. The corrected machine accuracy calculation unit calculates a post-correction machine accuracy from the expected accuracy data. The data display unit displays the post-correction machine accuracy calculated by the corrected machine accuracy calculation unit.
