Week 9

Rowan B, Daniel S, Micah B, Elijah M

Last Week’s Sponsor Meeting

• Onboarding / safety paperwork
• NDA / Hi-tech honeycomb intellectual property
• Limited photos of equipment
• Only certain CAD files can be shared
• Talked in depth with the operators about machine specs and current setup
• Different cutters used for each honeycomb cell size
• Force of cutting changes with cell size, smaller cells require more force
• Editing Project Scope
• Dependent on results of risk reduction, rotation will or will not be within project scope
• Discussed budget and project purchases
• Sponsor contact requested a bill of materials for the prototype, and they will get back to us after discussing with their supervisors

​

The Manual Cutting Process

• Manual cutting steps: table is rotated manually, a zeroing block is used, the angular stop is adjusted, cut is performed, cut is checked with gauge, and repeat.
• Final piece is checked in gauge block

Risk Reduction Progress

• Testing work in progress. Force sensors come in tomorrow
• Tested screw clamp (applied force until part could not rotate → no deformation).
• Compared rubber and high density foam on clamping face
• Began building custom clamping mechanism

Risk Reduction Plans

• Gather load force data to present to sponsor on Thursday

Standard screw clamp

Custom clamp

• Bring in clamps to sponsor on Thursday to test

Compare to manual operation precision

Design Steps

- Step 1 Clamping mechanism

-Material Testing

-Prototype in construction

- Step 2 Linear translation

- Between two slider options differing in length, depending on project scope

- Step 3 Rotation

Goals

3/6:

• Test custom clamp on production line
• Bill of materials

​

3/13:

• Present final design to director and engineer on site
• Complete risk reduction tests (vertical screw clamp and prototype “finger” clamp with force sensor)
• Prototype final design
• Initial bill of materials drafted for prototype construction
