Abstract

Single Minute Exchange of Die (SMED) refers to Quick Change Over (QCO), a process designed to reduce the set-up time of a production machine or a production line. The term "tool change" is misleading, since the time from the last good part of the old production lot to the first good part of the new production lot is meant and is better to be called "production change". The difference is that not the pure time of changing a tool is decisive, but also things like the provision of the new material or the parameterization of the machine and the like; The entire time in which it can not be produced.
