Abstract

The ram of the press is accelerated to an acceleration- terminating point whereat it attains a speed providing for the required energy of impact upon the work. During the acceleration, the velocity of the ram is measured, as well as the deviation of the actual point of attaining the required speed relative to the preset acceleration-terminating point. Depending on the value of this deviation, either the extent of the acceleration path is varied, with the acceleration value maintained constant, or else the acceleration rate is varied, with the acceleration path length remaining permanent. <IMAGE>
