How to reduce setup & changeover time using SMED technique of lean manufacturing?

SMED, short for Single-Minute Exchange of Dies, refers to a method in the Lean Production System that is used for quick, simplified and efficient production set-up and changeover from one product/process to another, which often constitute the major causes of production downtime (non-productive time/stoppages).



SMED has applications in development too and should be thoroughly considered in an unexpected way. The issue to be tended to is how might one diminish the set-up to finish a specific assignment. In this way, development professionals need to comprehend the center of SMED with its systems in Lean creation and embrace them to their work settings.


1) Observe the present approach:

Current procedures generally are recorded on video tape of all the setup/ changeover process. Get an activity or process where the changeovers/setups take a long time and the variability is high. Be sure to capture both “human” elements and “equipment” elements. A simple table can be created to investigate the setup/ changeover process (describing activities, activity durations, activity reparations, activity types - Internal or External)


2) Separate the Internal and External activities:

An important part of SMED is distinguishing between the Internal and External activities. For a converting process, we’ve providing a few examples:


Internal activities – Internal activity are those that must be performed when the procedure is halted. For example, changing a grinding wheel from grinding machine is an example of an internal activity.


External activities – These involved activities that can be performed while the machine is running. For example, this might include moving product materials to a storage area, staging the next product materials or gathering the tools and components for the next changeover.


3). Convert Internal Activity into External activity:

this change can be accomplished by getting ready staff, movement, instrument and information planning. A few interesting points are: situating, on-site device/equipment design, little prefabrication/changes, modularization, device tweaking, expanding on-site process straightforwardness and information stream and so forth. The inquiry is: If there was an approach to make this activity external, what might it be? How might we do it?


4). Optimize Internal Activity:

Since you've characterized the exercises, investigate how you're performing them. Is there an approach to create some new enhancements?

For example, you may find that members of one shift are setting the die or nip pressures at different levels. Perhaps you can mark the best setting on the machine (or on a chart) so all shifts adhere to it correctly.


5). Optimize External Activity:

In a similar regard, you can improve external activities too. Is there an approach to store raw material moves nearer to the changing over machine? For instance, you could make arrangements of info materials, rotary dies, parts – and make them look out for a truck close-by for the following job.


6). Include new changes and document new procedure to standardize process:

When you've characterized the Quick Changeover process, now comes the opportunity to altogether report it. Not exclusively will this fill in as the reason for future enhancements, however it will likewise give basic back-up in the event that PCs frameworks crash or paper documentation is lost.


We've addressed the requirement for therapeutic and pharma organizations to approve their procedures, such a large number of perusers might do this as of now. Some portion of the approval procedure incorporates keep exact records of the procedure

Yes!! SMED is indeed a great tool towards waste reduction. Thanks for sharing Harshil.
