Abstract
A machine tool diagnostic method includes: an initial acquisition step for acquiring initial measurement data by measuring multiple parameters of the machine tool while operating the machine tool in a predetermined operating pattern; a generating step for generating a normal area in a mapping space of a 1 class support vector machine method using the initial measurement data as training data; a reacquisition step in which, after operating the machine tool, the multiple parameters are measured to acquire re-measured data while again operating the machine tool in the predetermined operating pattern; and a diagnostic step for diagnosing the machine tool using the re-measured data as test data, based on whether or not the test data is contained in the normal area of the mapping space in the 1 class support vector machine method.
