    • Volume Flexibility
  • 7. Material Flow Cycle Moving stock from delivery to the actual warehouse shelves When one process is finished, but the job is waiting to be moved to the next work area The time a job spends in transit Job is where it should be, but is not being processed because other work precedes it Job is at the work station, and the work station is being "setup” Job is at machine and being worked on Cycle Time Input Output Other Wait Move Queue Setup Run
  • 8. Driving Improvement Critical for driving improvement to your customers

  • 11. SMED / Set-up Reduction
  • 12. Set-up Reduction
    • Is NOT
    • A program to eliminate set-up people
    • A panacea to overcome poor management or poor process layouts
    • A requirement to spend large capital investment to attain significant benefits
    • Is
    • A tool (like many) to reduce waste and excessive time
    • A low-cost method to achieve increased capacity from existing equipment
    • A process to reduce lot sizes and improve product mix
    • A cross-functional team approach to problem-solving
  • 13. Set-up Reduction – Traditional Practice
    • Material movement occurs after the machine is turned off
    • Completed products are transferred to next operation
    • Raw material is moved after the machine is stopped
    • Defects or missing equipment noticed when the machine is running
    • Setup tooling delivered after the changeover has begun
    • Defective product identified after internal setup has begun
    • Defective tooling, fixtures, setup instruments are noticed, after the machine is turned on
    • The operator notices that equipment is missing tools etc after internal setup has begun
  • 14. Set-up Reduction Goals Happy customer Improve tool and product design Improve idle asset usage Eliminate set-up / change-over time Reduce lot sizes Increased capacity / produc-tivity Increase flexibility through simplicity Improve mainten-ance costs Improved material flow and usage Reduce lead time Reduce scrap Reduce inventory costs Set-up Reduction Goals
  • 15. Set-up Reduction - Types Internal Executed while the machine is operating External Executed while the machine is stopped
  • 16. Set-up Reduction - Benefits Benefits Reduce indirect costs Improve customer service Experience fewer shortages and stock-outs Reduce queue times Improve cash flow Improve Inventory Turns Reduce overall Cost-of-Quality Become more competitive Increase equipment uptime Improve machine efficiency & level out production Utilise labor effectively Increase manf. process flexibility & capacity Improve overall management effectiveness
  • 17. Setup – Implementation Steps Integrate Internal into External Setup Reduction of Setup Processes Verify & Standardise Setup Review Set-up Process Steps Develop Implemen-tation Plan Develop Communi-cation Plan Develop Training Plan Implement Plan
  • 18. Setup – Process Steps Step 1: Prepare Finding materials, jigs, gauges, etc Could take 20~ 30% of the set-up process time Step 2: (Dis)Mount Taking tooling off / on the equipment Could take 5 ~ 15% of the set-up process time Step 3: Centre / Align (Re) Aligning equipment to run the next part Could take 10 ~ 20% of the set-up process time Step 4: Trial Run / Adj. (Re) Adjusting the equipment to run according to specs Could take 40 ~ 60% of the set-up process time Focusing here leads to set-up reduction times
  • 19. Set-up Reduction – Critical Success Factors CSF Elimination of waste Operators / set-up people are the owners of the process and its results 5S and Visual Control programs Team work Cross-functional team Small lot size production Training for operators and team Increase flexibility in equipment, processes and people Simple job changes Focus on equipment up-time Flow Charting current and proposed process
  • 20. Set-up – Improvement Process
  • 21. Set-up – Conversion Matrix
    • Purpose
      • Used to identify specific actions taken to convert internal setup operations into external setup operations as part of the SMED program
    • When to Use
      • Setup conversion matrix should be used after the setup work sheet (previous slide) has been completed
    • Who should use it
      • The set conversion matrix can be used by anyone involved in process improvement
    • Expected Benefits
      • The resultant deliverables will be specific actions aligned with conversion methods to convert internal setup operations into external setup operations
  • 22. Lead Time Reduction
  • 23. Lead Time - Definition
    • Lead Time - is the time from the receipt of the order to the delivery of the product
    • Cumulative Lead Time - the longest planned length of time to accomplish the activity in question
  • 24. Lead Time Reduction
  • 25. Lead Time Reduction
  • 26. Lead Time Elements Wait Run Transport Rework / Scrap Inspect Overpro-duction Excess inventory & WIP Queue Unneces-sary motion Ineffi-cient plant layout Lead Time Elements
