1. Presentation of Phase 3 Monday 12/11/2006 Nick DePompeo, Brian Hufe, Mike Sacra, Ben Stuchlik

2. Southco  Over the past 60 years, Southco has grown through innovation, strategic acquisitions and overseas investments into a global leader in Engineered Access Hardware.  DZUS quarter-turn fasteners provide quick, effortless access/fastening for military and aerospace applications.

3. Project Scope Definition  To accurately design and manufacture an interface between an MTS machine and required fasteners to produce an efficient and safe testing process for all required tests.

4. Current Process  Utilizes 3 machines Utilizes compressed air  Requires skilled, trained operator  Tensile, shear and torsional tests are performed Tensile/Shear Fastener Testing Tensile/Shear Receptacle Testing Torque Fastener Testing

5. Why Change?  Three required machines to run tests  Extensive Testing time  Repetitive Testing Process  Testing process may be inaccurate  Southco has an MTS machine available

6. Customer Wants  Decrease skill requirement of testing procedure  Decrease testing time  Maintain testing safety standards  Develop an interface with available MTS Machine  Increase repeatability and accuracy

7. Metrics  Number of machines  Testing time  Accuracy  Repeatability  Durability

8. Benchmark-Target Value Comparison 1)3 Machines1)1 Machine (MTS Machine) 2) Approximately 8-9 hours2) Less than 4 hours per lot 3) Unknown3) 10% more accurate than what is being tested 4) Unknown4) 10% more repeatable than current process 5) N/A5) Operational for a minimum of 10 years Benchmark ValuesTarget Values

9. Selected Concept: Single interface for all tests Reduced setup time between tests Easily allows for “nesting” feature

10. Key Pieces 1)Top U Piece 2)Bottom U Piece 3)Nesting 4)Rotator Pieces 3 1 4 2

11. Assembly Model

12. Nesting  Nesting allows for adaptation. New fasteners may be tested through the use of new nesting pieces.

13. Locking/Unlocking Fastener

14. Shear to Tensile Test Re-Positioning

15. Design Schematic

16. Testing Procedure 1) Attach interface to MTS machine 2) Load TestWorks and initialize test 3) Calibrate machine 4) Performed 3 trials of testing for 3- fastener lots using required testing order 5) Record data and analyze results

17. Testing Results  Interface works as intended.  Testing time reduced to target value.

18. Test Validation- Ease of Use Current System: Requires three Machines New System: Requires 1 Machine

19. Test Validation- Testing Time Testing Time has been reduced by approximately 4 hours Current testing time take approximately 8 hours per lot

20. Test Validation- Accuracy  Load Cell is much more accurate than the current compressed air system which can have leaks.  The new system is calibrated every time a new testing shift begins.

21. Test Validation- Repeatability  Testing showed a high degree of repeatability. Testing time had a low std. deviation

22. Value to Southco  Decreased testing time More lots can be tested in a given time.  Set testing procedure Detailed step-by-step procedure  Minimizes operator skill requirements  Takes up less space

23. Project Costs

24. Implementation Plan  Southco will be provided with the interface and necessary hardware/software.  Southco will be provided with a detailed operations manual, including engineering drawings.  Southco will be provided with a first- hand training session for operators.

25. Financial Payback Skilled operator salary: $30/hr Current Test Time: 8.5 hr Tests per day: 1 test = $255.00 per test Skilled operator salary: $30/hr New Test Time: 4.5 hr Tests per day: 1 test = $135.00 per test Estimated Savings = $120.00 per test At a total cost of $2410.85, it would take Southco approximately 20 days of testing to completely pay off the new testing system.
