For example, in the expander machine of rim manufacturing unit, additional time is needed for exchange of setup. These in turns stop the activities of other processes for about 90 minutes, which probably breaks the production of rim in this unit. As this setup exchange is inevitable, the only solution is to reduce the time consumption. At this point, the process of Single Minute Exchange of Die (SMED) comes into play. A SMED goal is a quick changeover of setup. It is a suitable method not only for improving manufacturing process but also for the equipment design development. Customers are expected to get the reliable products in a short time. To accomplish this, it is needed to eliminate and improve productivity and quality. It is a customer driven requirement who demands a product and service diversity, high reliability, quality and meeting customer satisfaction.An example application of SMED is in formula one (F1) racing during change the tires. When an auto racer stops in the pits for fuel, tires, water, and whatever else they need, they do not stop racing. In the pits, they are racing the clock because to stop means they are giving up their place to the competitors who are still on the track. Typically they are in and out of the pit in approximately 10 to 15 seconds. At the racing speeds of 200 miles per hour, an extra second in the pits represent over 200 foots on the racetrack. The margins of victory in many races are often in inches.How does that race cars get in and out of the pit so quickly? While it may not be obvious or easy, the concepts and methods used are fairly simple. First, the specific pit stop process is formally defined. Everybody on the pit crew knows his job and everybody focuses and steps up to achieve the overall objective of short pit times.
