SMED METHOD

Quick Changeover

Objectives

  • Reducemachine Changeover (set up) time
  • Reduce lost time and improve machine utilisation
  • Reduce batch sizes
  • Small batches = smaller production inventory =higher flexibility of production

Contents

  • 1
    Changeover time measured from the last good piece of Product A to the first good piece of new product B
  • 2
    The SMED (Single Minute Exchange of Die) method aims to optimise the exchange process, to standardise it and spread the optimised procedure
  • 3
    Internal activities are activities during changeover that are performed when the machine is stopped (e.g. form exchange, tool location, setting of operating parameters)
  • 4
    External activities are changeover activities performed during the machine’s operation (e.g. form preparation, documentation study, material exchange)
