This document outlines the 5 steps to implement SMED (Single Minute Exchange of Die) for quick changeovers: 1. Develop a one-step setup implementation team. 2. Separate internal and external setup operations to distinguish operations that can be done while the machine is running. 3. Convert internal setup operations to external where possible through techniques like mechanization and use of jigs. 4. Develop a one-step setup training plan to teach workers the new changeover process. 5. Implement the one-step setup and verify the standardized process through reduced changeover times.

- 6. Separate internal from external setup operations Convert internal to external setup Standardize function, not shape Use functional clamps or eliminate fasteners altogether Use intermediate jigs Adopt parallel operations Eliminate adjustments Mechanization
- 7. Internal and external setup operations must be distinguished. • Internal setup operations can only be performed when the machine is stopped. (Example: Mounting or removing dies) • External setup operations can be conducted while the machine is operating. (Example: Transportation of tools and parts to where they are needed.)
- 10. Streamlining of all aspects of setup operations. • Emphasis is on eliminating both internal and external operations to reduce overall setup time. This involves investing in technology such as product redesign, new tooling, or automation.
- 11. Stockless production which drives capital turnover rates, Reduction in footprint of processes with reduced inventory freeing floor space Productivity increases or reduced production time Elimination of unusable stock from model changeovers and demand estimate errors Goods are not lost through deterioration Ability to mix production gives flexibility New attitudes on controllability of work process amongst staff

- 15. For example: A slide clamp reduced the time required to load and unload parts to fixture. 2 hold-down clamps eliminated the need to tape parts during a glue-up operation. Set slide allows quick (temporary) alignment of 2 parts. SMED Examples
