Wes Demirjian
Freestanding NPI
• From Nashville, TN
• Junior at TN Tech
University
• Mechanical Engineering
• First Rotation
• Freestanding NPI
• Mentor: Jamie Little
• Literature
• Controls Rework
• Torque Tests
• Pre-Pilot Build
• Other Assignments
• New models (with new
software) mean new literature
• Proofread existing manuals,
omitting obsolete details and
adding new information
• Used new graphics to form a
rough draft of what the new
Use and Cares might look like
• Updating software and hardware separately caused EMI
issues
• Fixed issues by modifying one connection on circuit
board
• Problems with stripping
screws during previous build
• Took different fasteners and
different hole types to test the start
and strip torques of all possible
production variations
One instance (CR control trim) showed that only one out of
three of the current screws was satisfactory in a sense that the
maximum start and minimum strip torques were a great deal
separated
• Rework
• Loops
• UL/Miswire FMEA
• Overlay Tape Design
• Warping Control
Trims: Details
• Doors failing STTs:
Analyzing
• DST
Abrasions:
Simplicity
• Everything in industry takes longer than
expected
• Flexibility is
essential
• It’s not what you know, but who you
know

Editor's Notes

  1. Good way to learn about different models and industry lingo and special functions
  2. Learned a lot about range electronics; first of many steps to a lot of work I would do during co-op
  3. 1.) .020” here and .015” there can add up! 2.) Many minds are greater than few; multiple modifications caused doors to pass STT 3.) Don’t over-engineer: Simple fixes work
