SMED simulation

1. SMED simulation

2. SMED simulation
Purpose:
Participants:
Duration:
Simulates die changeover on a very
simple machine with the purpose to
teach the 5 steps of SMED (Single
Minute Exchange of Dies)
At least 3
2-3 hours

3. A. 1 wood base: 11 x 5-1/2 inches
B. 1 wood crossbar: 11 x 1 inches
C. 1wood square die “A”: 3 x 1-1/7 inches
D. 1 wood square die “B”: 2 x 1-1/7 inches
E. 1 wood square block: 1 x 1-1/7 inches
F. 1 round head bolt: 1/4 in - 20 x 2 inches
G. 1 t-handle screw: 1/4 in - 20 x 2 inches
Components
H. 1 thumb screw: 1/4 in – 20 x 1-1/2 inches
I. 1 technical measuring set: 6 pieces
J. 1 flare nut wrench: 5 pieces

4. Procedure
a. Preparation
• Have a chronometer for time measurements
• Have a flipchart and post-its to track results during
each iteration and include key notes during the
simulation
• Have the tools over a table

5. b. Initial setup
Procedure
Raw material

7. Procedure
c. Alignment requirements
Requirement: 5 mm
5mm

8. Rules of the simulation
d. Allocate roles to participants
The simulation must have at least 3 participants with the following functions:
e. Define goals for each step (iterations)
In the end of each iteration the group creates suggestions for improvement
and evaluation of the cost/benefit.
• 1 operator
• 1 quality controller
• 1 material handler
• 1 time keeper/flip chart person
• 1 video recording

9. SMED simulation steps
1: Measure the actual situation
2: Separate internal and external events
2: Convert internal to external events
3: Reduce internal events
4: Reduce external events
