Method of controlling a machine tool operating at different working speeds includes triggering, by a fixed time interval, that is the same at all working speeds and is a characteristic of the machine too, the start of an operating cycle of the machine tool each time a moving element of the machine tool reaches a given starting position that is the same at all working speeds; the triggering being preceded and controlled by an activating switching step each time the element reaches a given activating position spaced at a constant distance from the starting position thereof and selected so that the total time required by the element to traverse the constant distance from the activating to the starting position is not shorter, even at maximum working speed of the machine tool, than the fixed time interval; and interposing between the activating and triggering steps, when the total time exceeds the fixed time interval at a particular working speed, an additional time interval depending upon the particular working speed and equal to the difference between the total time and the fixed time interval; and control system for performing the method.
