Eight Principles of SMED
Mr. Rogers explains six basic steps of Single Minute Exchange of Die (SMED) basics and its eight principles.
Mr. Rogers explains SMED basics and its eight principles.
Six basic steps of SMED are:
- Measure changeover times
- Identify internal and external elements
- Move external elements to external
- Shorten internal elements
- Shorten external elements
- Standardize and maintain new procedure
Eight principles of SMED are:
- 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
