Final Concept Selection
•
•
•
•
•
•
•
•
•
Combination of best components from each system concept
Different fixture for each model
PLC/HMI display with LED lights
Manual Door Slide with electric door interlock
Locate and secure nozzle using a yoke plate (previous MSD team)
Manual input with a scanner
Electric Centrifugal pump to circulate oil
Internal reservoir to store oil
Gravity flow to return oil to reservoir

Cost
Budget: $10,000
Estimated costs of major components based on benchmarking:
•
•
•
•
•
•
HMI/PLC - $800
Sensors - $250
Door Lock - $50
Pump - $500
Door handles - $10
Oil lines - $80
Total: $1,690

Engineering Analysis
• How many fixtures are needed/What parts need to change?
•
Prototype different options
• How long will a changeover take?
•
Prototype a fixture and time a mock changeover
• Will the pump provide appropriate pressure and duration?
•
Benchmark
• Which type of door lock ensure safety and eliminate leaking?
•
Benchmark
• Will all of the sensors be compatible with the PLC?
•
Benchmark

●
●
Pump--verify the pressure at different points
Pneumatics--verify cylinder actuation and verify no bleed-off
Pressure sensors--verify they meet specs
Fixturing alignment--verify part fit-up with oil injector
Cycle time--different parts and change-over
Door lock--verify that the door will not open during operation
Noise level--verify less than 50dB
Scanner--verify communication with PLC and pulls up correct parameters
LED and HMI--verify the systems output the correct data at the correct time
User interface--verify intuitive controls
System Control--verify system runs correct parameters and operates as planned

Lessons Learned
•
•
•
•
Have a method to track risks at a high level
Project schedule may vary from MSD schedule
Have document owners
Practice design review with your guide
