SMED
SMED (Single-Minute Exchange of Dies) is a set of organisational and technical methods used to reduce the set-up and re-tooling time.The general SMED programme structure as follows:
1. Indicate a point to be improved.
2. Set up a task group.
3. Indicate an adjustment process (timing).
4. Phase #1: divide the phases into exterior and interior ones.
5. Phase #2: transfer all possible adjustment processes to exterior ones.
6. Phase #3: optimise set-up timings (organisational and technical methods).
7. Carry out a re-timing after the programme being completed and specify a targeted indicator.
8. Develop other activities, which provide a continuous improvement.
9. Install a board to control the SMED targeted indicators.
10. Prepare a final presentation.
1. Indicate a Point to Be Improved
It is necessary to analyse the equipment at the plant to detect critical units (bottlenecks) and to indicate the point subject to SMED. Further, this experience can be applied to a similar equipment.
2. Set up a Task Group
The task groups, which include the following specialists, are able to solve the issues of set-up and re-tooling timing optimisation in the most effective way:
- production specialist – team leader;
- workers who operate the equipment;
- lean production specialist – process team leader;
- process engineer;
- maintenance service specialist;
etc.
The team leader gives specific and measurable tasks to other group members.
3. Indicate an Adjustment Process
The task group describes the real situation on the shop floor (Gemba) first and divides the whole process into stages and junction elements. Further, it is necessary to make a timing (video recording) and, at the same time, to detect the problems that impact on safety and stage completing time.
