Method of diagnosis of a machine tool, corresponding machine tool and computer program product

Abstract

A method () of diagnosis of operation of a machine tool () that includes one or more axes (X, Y, Z) moved by one or more actuators () and at least one sensor () coupled to the machine tool (), the method () comprising operations of: generating () a programming sequence of movement of the axes (X, Y, Z) of the machine tool (); controlling () the movement of the axes (X, Y, Z) of the machine tool () according to the programming sequence; receiving () a read-out signal (S) of the at least one sensor () coupled to the machine tool (); and processing () the read-out signal (S) of the at least one sensor () coupled to the machine tool (). The programming sequence comprises instructions that are such as to apply (T) at least one single impulsive variation of a kinematic quantity that regards one or more actuators (). The operation () of processing the read-out signal (S) comprises processing a response of the machine tool () to at least one single impulsive variation. The operation () of processing the read-out signal (S) comprises artificial-neural-network processing () via one or more artificial neural networks () configured for analysing operating profiles in particular, one or more signals indicative of the status of the machine tool (W) in the read-out signal (S).
