Eight Principles of SMED

Mr. Rogers explains SMED basics and its eight principles.

Six basic steps of SMED are:

  1. Measure changeover times
  2. Identify internal and external elements
  3. Move external elements to external
  4. Shorten internal elements
  5. Shorten external elements
  6. Standardize and maintain new procedure

Eight principles of SMED are:

  1. Separate internal from external setup operations
  2. Convert internal to external setup
  3. Standardize function, not shape
  4. Use functional clamps or eliminate fasteners altogether
  5. Use intermediate jigs
  6. Adopt parallel operations
  7. Eliminate adjustments
  8. Mechanization

If you’d like to know more about running SMED workshop read this article by Dr. Roser. For more details regarding the eight principles of SMED see this excerpt from Shingo’s book (1985).

Read the following short papers in which the authors describe how they applied SMED on:

  • injection presses used for Styrofoam products, by Ulutas (2011);
  • PLCC Tape and Reel machine, by Tharisheneprem (2008); and
  • machine tool manufacturing, by Bharath and Lokesh (2008).
