SMED, internal and external setup, value added and non value added activity, total productive maintenance, total employee involvement


Single Minute Exchange of Die is popularly known as SMED. It is a phrase coined by Shigeo Shingo at Toyota Motors in the 1960s and has come to be used as a synonym for fast changeover. SMED was the result of a project that Toyota had assigned to Shigeo Shingo. Toyota realized that they needed to make more than one model car to succeed. They also realized that multiple car models meant multiple changeovers of stamping presses. Under this strategy, they could no longer live with 10 to 12 hour press changeovers. Shingo used standard industrial engineering techniques to analyze the changeover. These and other techniques allowed Shigeo Shingo to reduce the typical press changeover from 10 to 12 hours to less than 10 minutes. The tools and techniques developed are widely known as SMED. This paper presents applications of similar SMED tools and techniques for improving productivity on 200 Ton press in an automotive component manufacturing industry in Nashik. Overall productivity improved by 50% using some of the SMED tools and techniques.
