DETERMINING AT LEAST ONE REFORMING PROCESS INDICATOR OF A SERVO PRESS

The invention relates to a method of determining at least one reforming process indicator of a servo press. The method includes at least the following steps: determining a torque change process of a motor of the servo press belonging to a first cycle of the servo press, wherein the first cycle indicates that there is no forming process of an article to be machined by the servo press; determining atorque change process of a motor of the servo press belonging to a second cycle of the servo press, wherein the second cycle describes a forming process of the article to be machined by the servo press; obtaining at least one forming process characteristic parameter from a comparison of the torque change process belonging to the first cycle with the torque change process belonging to the second cycle. The invention also relates to an associated evaluation unit for deriving a forming process characteristic parameter of a servo press. 本发明涉及一种用于确定伺服压力机的至少一个成形工艺特性参数的方法，该方法包括至少以下步骤：确定伺服压力机的马达的、属于伺服压力机的第一周期的转矩变化过程，其中第一周期说明
