摘要： On a numerically controlled machine tool a sub-program is integrated into the given program for controlling the machine tool by which a periodic change of at least one cutting tool parameter is effected in one processing cycle, or also in several processing cycles, or in certain length and diameter zones of the workpiece characterized by tool vibrations and leading to inferior workpiece quality. By way of the periodic cutting parameter change, self-excited tool vibrations are avoided in these sensitive machining areas, thereby enabling tool wear to be reduced and workpiece quality improved. Furthermore, this intervention into the machining program is documentable and identically reproducible for each workpiece—independently of the expertise and personal judgement of the operator.

摘要： A control device of a die cushion mechanism, by which a force between a slide and a die cushion may follow a commanded value even in the rapid acceleration or deceleration of the slide and, moreover, a problem such as vibration of the mechanism may be prevented in the gradual acceleration or deceleration of the slide. The control device includes a slide position detecting part, such as a position sensor, for detecting the position of the slide and a correcting part for correcting a current commanded value using an acceleration of the slide, obtained by second-order differentiation of the position of the slide detected by the position sensor.
