• SMED is continuous improvement
• It is a customer driven requirement

  SMED
• Customers are demanding:

  • product and service diversity
  • lower costs
  • higher reliability and quality
• In essence organizations need to become leaner
• organizations must:

  • produce smaller lots, more frequently
  • expand the scope and diversity of products and services
  • reduce quality defects
• ULTIMATELY, SMED focuses on reducing changeover and set-up times
• organizations meeting their goals enables them to meet customer's expectations and demands
• SMED means?


  Single-Minute Exchange of Die
• SMED is the set-up and changeover reductions for equipment, tooling and machines
• What does Set-up/changeover reduction mean for my business?

  • increased customer service levels and profits
  • Via Waste Elimination resulting in:
  • Reduced Lead Times-Faster Delivery
  • Zero Inventories-Reduced Working Capital
  • Improved Quality
  • Improved Safety
  • Smaller lots of products-flexibility
  • Diversified Product and Service Options
• Why SMED?

  • To eliminate wastes that result from "uncontrolled" processes increasing inventories and lead times
  • to gain control of equipment, material, and inventory
  • apply control techniques to eliminate erosion of improvements
  • standardize improvements for maintenance of critical setup parameters
• Traditional set-up practices

  1. Material movement occurs after the machine is turned off
  2. Detection of defects or missing equipment is noticed which the machine is running
  3. Defective tooling, fixtures, setup instrument s are noticed after the machine is turned on
• 5 Traditional Set-up Steps

  • Preparation
  • Mounting and Extraction
  • Establishing Control Settings
  • First Run Capability
  • Setup Improvement
• Ensures that all the tools are working properly and are in the right location

  preparation
• involves the removal of the tooling after the production lot is completed and the placement of the new tooling before the next production lot

  Mounting and Extraction
• Setting all the process control settings prior to the production run

  Establishing Control Settings
• Inclusive of calibrations and measurements needed to make the machine, tooling operate effectively

  Establishing Control Settings
• This includes the necessary adjustments (calibrations, additional measurements) required after the first trial pieces are produced

  First Run Capablity
• The time after processing during which the tooling, and machinery is cleaned, identified, and tested for functionality prior to storage

  Setup Improvement
• involves standardizing the equipment (parts, tooling, processes) base on commonality between setups to reduce the number of setup steps and cycle times

  Combining equipment functionality
• Elimination of bolts and adjustments are in what phase

  Reducing setup processing time
