Problems in the press shop sometimes are blamed on poor press-setup practices, when the source of the problem actually may lie with the die design or the press selection. Press selection usually is predetermined by process engineering or tool engineering prior to tool construction. At this early phase of process development, engineers often estimate pressing forces to ensure that the press selected has adequate force capacity. They also will estimate die size to ensure that it will fit in the press. Unfortunately, little consideration, if any, has been given to the negative effects of off-center loading on part quality and die life.
