SMED Tip of the Month



Achieving Lean Changeover: Putting SMED to Work Is a book from Productivity Press. Order here: 


http://www.crcpress.com/product/isbn/9781466501744


It's also a workshop presented in your plant to teach lean changeover techniques.


Both are jammed with practical examples that you can implement today to make changeover faster and more accurate.


This page will be updated monthly with examples taken from the book. If you would like to be notified updates enter your email address below the tip.


If you do not yet have your copy of the downtime loss calculator, drop a note to johnhenry@changeover.com
Little improvements can make a big difference. Eliminating 10 minutes of daily downtime results in 40 hours of additional uptime per year.

This month's tip comes from my Achieving Lean Changeover: Putting SMED to Work book and workshop. It is something that seldom occurs to most people. It never occurred to me until I read Shingo's book on SMED.

Screw threads.

All holding in a threaded fastener is done by the threads in the male and female component. Yet how many times do you see a bolt with a half inch, an inch or more of thread extending above the fastener. These threads serve no purpose except to waste time.

They should be eliminated.

Cross threading can also be a problem. This can be eliminated by removing the unneeded threads while leaving the root. The nut slides down and when the threads make contact they are perfectly aligned.
