SMED simulation

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

A. 1 wood base: 11 x 5-1/2 inchesB. 1 wood crossbar: 11 x 1 inchesC. 1wood square die “A”: 3 x 1-1/7 inchesD. 1 wood square die “B”: 2 x 1-1/7 inchesE. 1 wood square block: 1 x 1-1/7 inchesF. 1 round head bolt: 1/4 in - 20 x 2 inchesG. 1 t-handle screw: 1/4 in - 20 x 2 inches

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

Rules of the simulation

d. Allocate roles to participantsThe 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

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
