Familiar Terms?

 SMED:

  • Have you participated in a SMED activity before?

 Lean:

  • Do you know what is Lean?

 Changeover:

  • Are you involved in changeovers?
  • SMED Workshop
slide-4
SLIDE 4

Continuous Improvement Toolkit . www.citoolkit.com

 Stands for: “Single Minute Exchange of Dies”.  Activities designed to reduce and simplify changeovers.  SMED is one of the many Lean methods

for reducing waste in manufacturing processes.

 SMED is a philosophy where the target is

to reduce changeover time to few minutes.

  • SMED Workshop
slide-5
SLIDE 5

Continuous Improvement Toolkit . www.citoolkit.com

  • SMED Workshop

“Single Minute” means: Necessary changeover time is counted on a single digit. Why “Exchange of Dies”? Toyota found that the most difficult tools to change were the dies on the large transfer-stamping machines that produce car vehicle bodies.

History of SMED:

 Shigeo Shingo was the originator of SMED system at Toyota in

the 1970s.

 Toyota reworked factory fixtures and vehicle

components to maximize their common parts and standardize assembly tools and steps, and utilize common tooling.

 These standardized steps reduced

change-over time from 3 hours to 3 minutes.

  • SMED Workshop

Changeover:

 The time between the last good piece of one run at production

speed, and the first good piece of the next run at production speed.

Typical Change Over Activity:

  • SMED Workshop

50% Trial Runs and Adjustments 30% Preparation 5% Mounting & Removing Tools 15% Centring and Setting

The work that is done to prepare for changeover to ensure all tools are working properly and are in the right location including finding material, jigs and gauges Involves the removal of the tooling off the equipment and the placement of the new tooling Setting all the process control settings and fine-tuning the tooling and equipment to run the next part Involves the frequent trial-and-error approach to set up the tooling and equipment to run the parts according to specifications

slide-11
SLIDE 11

Continuous Improvement Toolkit . www.citoolkit.com

Why Reduce Changeover Time?

 In the past, customer demands were for large volumes of the same

product.

 Now, the current trend is moving towards smaller batches.  If changeover time is not reduced, it will not be possible to produce the

same volume in the same period of time.

  • SMED Workshop
slide-12
SLIDE 12

Continuous Improvement Toolkit . www.citoolkit.com

Changeover vs. Maintenance:

 Changeover is The removal/replacement/adjustment of alternative

part(s).

 Maintenance is: The removal/replacement/adjustment of the same

part(s).

  • SMED Workshop

Good changeover practice equates to good maintenance practice

“Do better things”

slide-34
SLIDE 34

Continuous Improvement Toolkit . www.citoolkit.com

Some Design Ideas:

 Simplify fittings and tightening.  Minimize turning movements which request several grasp-release

  • motions. Aim to fit at once in a single motion.

 Use shims and spaces to reduce the distance

machine components need to move.

 Standardize types and size of parts and tooling

(screws, nuts, bolts, etc.) based on commonality between changeovers. This will reduce the number of setup steps.

 Fabricate equipment improvements.  Use technology and new tooling.

  • SMED Workshop
slide-35
SLIDE 35

Continuous Improvement Toolkit . www.citoolkit.com

Some Design Ideas:

 Look for:

  • Any attachment points that take more

than one turn to fasten.

  • Unheated molds which require several

wasted tests before they will be at the temperature to work.

  • Inadequate or incomplete repairs to

equipment causing rework and delays.

  • Mistakes or inadequate verification of

equipment causing delays.

  • Using devices to help in detecting errors.
  • SMED Workshop

Example of One Step Fastening This clamp attachment requires one step to attach the die to a machine

The 4 Steps to Reduce the Changeover Time:

1.

Observe and measure.

2.

Separate internal and external activities.

3.

Convert internal to external activities.

4.

Streamline, improve and standardize.

  • SMED Workshop
slide-41
SLIDE 41

Continuous Improvement Toolkit . www.citoolkit.com

STEP1: Observe and Measure:

 The aim is to record data about the way

people work during changeover.

 Data need to be collected in order to analyze

the changeover accurately.

 Production plan and schedule should be followed.  Changeover operators should do the first changeover as normal.  Analysis of changeover procedures using videotapes.  Study the video in detail noting the time and motions involved in

each stage.

 Record improvement ideas.

  • SMED Workshop
slide-42
SLIDE 42

Continuous Improvement Toolkit . www.citoolkit.com

STEP1: Observe and Measure:

 What is the problem?  What is the target?  What is the current changeover time?  What time can we get it down to?  What are the activities needed to perform

the changeover?

 What is the actual average time length

per activity?

 Who will participate in the team?

First Changeover:

 Prepare the team for the changeover – who does what?

  • Cameraman: Follow the main activity.
  • Time keeper: Record time for each activity using stop-watch and

the total cumulative time as well.

 Make sure a clear signal is given

to the time keeper as to when changeover starts (when the machine runs down).

  • SMED Workshop

STEP2: Separate Internal and External Activities:

 Aim: Separate activities which can be done while the machine is

running from those which must be done after it is switched off.

 External Activities:

  • Can be conducted while the machine is operating.
  • Examples:
  • Finding tools and transportation of tools and parts.

 Internal Activities:

  • Can only be performed when the machine is stopped.
  • Example:
  • Changing tools and dies.
  • SMED Workshop
slide-48
SLIDE 48

Continuous Improvement Toolkit . www.citoolkit.com

STEP2: Separate Internal and External Activities:

 Emphasize that tools should be found before the machine is

switched off.

 Isolate individual activities then sort them sequentially.  Separate them into internal and external activities.  Reduce useless and non-value activities.  Reduce adjustments and trials

as much as possible

 Get it right the first time.

 Use Changeover Wall Chart to divide changeover into

activities which need to be separated into internal and external activities.

  • SMED Workshop
slide-51
SLIDE 51

Continuous Improvement Toolkit . www.citoolkit.com

STEP3: Convert Internal to External Activities:

 Analyze each internal activity to

determine whether or not it can be converted into external.

 Do as much as we can before the

machine is switched off and after the machine has been turned on again.

 You might need to restructure the

changeover or setup procedure.

 Or apply process innovation or technology.  The SOP should then be adjusted.

STEP4: Streamline, Improve and Standardize:

 The aim is to reduce the internal and external activity time and

streamline the changeover process.

 Discuss each activity on the wall chart.  To prioritize efforts, you might need to

carryout a Pareto Analysis.

 It might be necessary to go on the gemba

and work with other departments.

  • SMED Workshop

Safety should never be compromised in the effort to reduce changeover time.

STEP4: Streamline, Improve and Standardize:

 Eliminate wasteful, unnecessary & redundant activities.  Eliminating both in internal and external non-value activities to

reduce overall setup time.

 Identify and eliminate wasted motions and movement around

the machine.

 Eliminate all mechanical and physical

variation.

 Reduce adjustments as possible.  Implementing parallel activities

as possible.

Think of:

  • Can we externalize activities?
  • Some items take a long time because they are complex, can we

simplify them?

  • Can we re-design to eliminate activities?
  • Can we combine activities so they can be done quicker?
  • Can we perform tasks in parallel?
  • Can we reduce the amount of time taken in any way?
  • How can we create a more disciplined workplace in

which changeovers are faster and more reliable?

What’s Next:

  • A new Standard Operating Procedure(SOP) must have been

developed and agreed by the shop floor people.

  • The team should develop a continuous improvement action plan.
  • The team should put what was taken from the workshop into practice.
  • The team may conduct some practice runs to be more comfortable

with the new practices.

  • Continuous evaluation and exploration of

further improvements is absolutely necessary.
