Abstract: In order to increase the accuracy of status or failure diagnosis of machine tools and reduce the time and costs required for data collection and algorithm development for diagnosis, sensors are mounted on specific elements of the machine tools and measurement data is collected while operating under the specific operating conditions during a time interval between one machining operation and another machining operation to perform status or failure diagnosis of the machine tools. According to the present invention, by using data collected while operating machine tools under the predefined specific conditions using a time interval between one machining operation and another machining operation, it is possible to more accurately perform diagnosis while allowing less noise to be mixed in the data and reducing the time required for data collection for the development of diagnostic algorithm.
