  1. PECOPRODUCT DESIGN SPECIFICATIONS REPORT PRESENTATION Group Members: Jonathan Boschiero Kiehl McIntyre Jeff Bennett Ryan Ernst

  2. PECO Manufacturing, Inc. produces fuel tank access doors for installation on Boeing aircraft.

  3. A completed door consists of a nylon panel with twenty three internally threaded metal inserts pressed into pockets around the perimeter.

  4. Mission Statement The PECO capstone design team will redesign Lola to eliminate deficiencies in its current design. Systems that identify correct insert type, provide consistent and verified insert temperatures, and verify correct pressing depth will be designed, prototyped and installed.The design will be completely documented by a design report including: analysis, detailed drawings, and a bill of material.

  5. The process of interest is the pressing of inserts into the pockets. There are three problems with the insertion process: • The wrong type of insert may be pressed into a panel. • Installed inserts may not meet pull-out and torque-out requirements. • Inserts may not be pressed to the correct depth.

  6. Insert type pressed is incorrect PECO produces 2 models of fuel access door.

  7. Insert type pressed is incorrect There are two paths that lead to the wrong insert being pressed: • Inserts may be left in the machine between set-ups. • Inserts loaded into the machine may be mixed. To ensure only inserts of the correct type are pressed: • A quick and reliable method to remove unused inserts between set-ups is needed. • Inserts loaded into the machine need to be identified as the proper type before being pressed.

  8. Failing to meet pull-out and torque-out requirements Success of the pressing process is dependent upon temperature. • Inserts pressed at a temperature that is too low fail to meet pull-out and torque-out specifications. • However, if the temperature is too high, nylon flows out from around the insert causing undesirable features. • Control of insert temperature before pressing is needed to ensure pull-out and torque-out specifications are met.

  9. Pressing depth is incorrect Inserts must be pressed to a specified depth below the surface. • A flange around the circumference of the ram limits maximum pressing depth by contacting the panel surface. • While the flange does limit maximum depth, if too little force is applied the insert will not be pressed to the minimum depth. • The depth to which inserts are pressed needs to be verified as correct during machine operation.
