Single-minute exchange of dies is a lean manufacturing concept that has grown beyond the world of metal forming. It now stands for any lean exercise that attempts to reduce changeover time to single-digit minutes. In implementing such a program, manufacturing managers need to understand the common pitfalls that plague these efforts.

Heavy plate fabricators drill and mill plate to achieve tight tolerances. But these metal cutting tools exert significant forces on the workpiece vibration, particularly in large workpieces such as plate. When machining in general and especially in large plate, three major factors work together: cutting tool selection, milling strategy, and workpiece setup.
