The dies — which must be changed for each model — weigh many tons, and must be assembled in the stamping machines with tolerances of less than a millimeter, otherwise the stamped metal will wrinkle, if not melt, under the intense heat and pressure.

When Toyota engineers examined the change-over, they discovered that the established procedure was to stop the line, let down the dies by an overhead crane, position the dies in the machine by human eyesight, and then adjust their position with crowbars while making individual test stampings. The existing process took from twelve hours to almost three days to complete.

Single-minute exchange of die

Toyota's first improvement was to place precision measurement devices on the transfer stamping machines, and record the necessary measurements for each model's die. Installing the die against these measurements, rather than by human eyesight, immediately cut the change-over to a mere hour and a half. Further observations led to further improvements — scheduling the die changes in a standard sequence as part of FRS as a new model moved through the factory, dedicating tools to the die-change process so that all needed tools were nearby, and scheduling use of the overhead cranes so that the new die would be waiting as the old die was removed.

Using these processes, Toyota engineers cut the change-over time to less than 10 minutes per die, and thereby reduced the economic lot size below one vehicle. The success of this program contributed directly to just-in-time manufacturing which is part of the Toyota Production System.

SMED makes Load balancing much more achievable by reducing economic lot size and thus stock levels.

Shigeo Shingo and His Contributions to Total Quality Control

Effects of implementation[ edit ] Shigeo Shingo, who created the SMED approach, claims [4] that in his data from between and that average setup times he has dealt with have reduced to 2. Separate internal from external setup operations Convert internal to external setup Standardize function, not shape Use functional clamps or eliminate fasteners altogether Use intermediate jigs Adopt parallel operations see image below Eliminate adjustments Mechanization NB External setup can be done without the line being stopped whereas internal setup requires that the line be stopped.

He suggests [6] that SMED improvement should pass through four conceptual stages: A ensure that external setup actions are performed while the machine is still running, B separate external and internal setup actions, ensure that the parts all function and implement efficient ways of transporting the die and other parts, C convert internal setup actions to external, D improve all setup actions.

Internal activities are those that can only be performed when the process is stopped, while External activities can be done while the last batch is being produced, or once the next batch has started. Convert where possible Internal activities into External ones C pre-heating of tools is a good example of this. Streamline the remaining internal activities, by simplifying them D.

Focus on fixings — Shigeo Shingo observed that it's only the last turn of a bolt that tightens it — the rest is just movement. Streamline the External activities, so that they are of a similar scale to the Internal ones D.

Document the new procedure, and actions that are yet to be completed. This diagram shows four successive runs with learning from each run and improvements applied before the next. Run 1 illustrates the original situation.

Run 2 shows what would happen if more changeovers were included. Run 3 shows the impact of the improvements in changeover times that come from doing more of them and building learning into their execution.

By , he was working at the Japan Management Association Technical Conference where he began looking into productivity problems associated with the plant. He began his research in early on Statistical Quality Control, after which Toyota leveraged his project and work.

After achieving excellent results with his theories, they hired him as a consultant.

What is SMED (Single Minute Exchange of Dies)?

By Dr. Shingo was already leading the industrial engineering and factory improvement training team at the Toyota Motor Corporation. In , he led a three-year study on shipbuilding at Mitsubishi Shipbuilding and came up with a system that halved the production time. He is also credited with the completion of the SMED, or single-minute-exchange of die method which is a type of Lean manufacturing method.

He achieved zero quality defects by leveraging the improved version of SMED. His principles still form the backbone of what quality control is all about to this day. Shingo in collaboration with Mr. Taichii Ohno from the Toyota days. To summarize the concept, this is a planned way to eliminate all waste along with continuous improvement in productivity.

It encompasses a perfect synergy of all activities related to manufacturing a particular product. A few primary elements of JIT would be: To have only the required amount of inventory at a given time Improve quality to have zero defects To reduce lead time by reducing setup times Optimize queue lengths and lot sizes The key thing to remember is to accomplish the above at minimum costs.

If a company were to apply the above tenets, they would be able to cut costs in an optimized and effective manner. Also, the use of statistical methods helps ensure that the product is met with desired results consistently.After reading, you will understand the basics of this powerful and efficient manufacturing philosophy and quality management tool.

Why SMED is necessary

Many companies that have stamping operations have found great success using his methods. He is said to have attained Kaizen, the Japanese word associated with improvement.

In this book they are referred to as setup operations. Storage of the finished product 3. His idea was to isolate and identify the time required for setup into two main entities: internal time and external time.

The additional 7 or 8 case studies could have been published into a companion book.
