Abstract
For a cycle of a cyclically operating machine, the internal tool pressure is detected during the cycle as a function of the time and/or as a function of the path traversed by the conveying means. The internal tool pressure course is then differentiated as a function of the time or of the path. It is then checked whether, by way of the previously determined derivatives, there are deviations from a monotonic course. If this is the case, the holding pressure time or the change-over moment are changed until the internal tool pressure curve has a monotonic course.
