METHOD OF COMPENSATING FOR SHUT HEIGHT VARIATION

摘要

A method for compensating for the variation in shut height of a press (4) during stamping and forming as it is starting and stopping comprising user input of the minimum press speed at which feeding (1) of feed material (2) to the press (1) should commence, monitoring (6) of the actual press speed, and feeding (1) of the feed material (2) only when a minimum press speed representing a desired press shut height has been achieved. A method for inputting a desired shut height range, monitoring (7) actual shut height and feeding (1) feed material (2) only when the actual shut height is within the desired shut height range is also disclosed.
