SET-UP REDUCTION Or SINGLE MINUTE EXCHANGE OF DIE (SMED)

Set-up reduction is a valuable tool utilized in the effort to decrease overall costs and lead-times. Set-up or “change-over” is defined as the time required from the unloading or completion of the last good part until the production of the first good part of the next run. Broadly defined, set-up includes unloading of tooling and fixtures, getting new tooling, getting tools, loading fixtures, getting materials, getting paperwork and inspection of the first part. This entire process can take place in less than 10 minutes!
A common concern exists in companies that reduction in the number of parts made before changing over will adversely affect the amount of product able to be produced. Focus is typically on Economic Order Quantity (EOQ) and amortization of cost setup over a larger number of parts. The resulting emphasis on large production runs and large lot sizes increases inventory, inventory holding and capital costs and extends the time to build and deliver the product. Lead-times are longer and costs are higher.
The SMED process focuses on reduction of setup and changeover time as a way of reducing lot sizes. Changeover of machines or processes can be accomplished in less than ten minutes and serves as a goal for change.
Benefits of a set-up reduction or SMED program include:
  • Reduction of inventory
  • Dramatic reduction in lead-time for the product
  • Elimination of waste and nonvalue-added operations
  • Improvement of plant capacity
  • Increase in manufacturing flexibility
  • Improvement in quality as lot sizes and lead-times shrink
  • Improvement in cash flow through reduction of inventory and rapid conversion of raw materials into saleable product
  • Increase in competitiveness
Set-up Reduction training is offered as a seminar with 10 to 15 participants in attendance. The training consists of classroom sessions and the videotaping of several set-ups and process changeovers, which are carefully analyzed for potential improvements in set-up changes. At the completion of the seminar, each participant will be able to analyze and reduce nonvalue-adding activities in their area.
