Week 10

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Tests pending completion of prototype

  • Final design work having kinks worked out

  • Fabrication near completion--will finish and assemble by Wednesday evening

Accomplishments from Previous Week

• • Puck assembly fabrication 90% complete; only a few flanges still to machine, then ready to assemble and Loctite in place.

  • Hard stops machined, ready to integrate;

  • Spring steel flexures machined; mounting block undergoing v2. machining; machining of blocks to hold roller bearings nearly complete;

  • Base plate ready for machining (this should be a big endeavor, but then all the final assembly is ready);

  • Poster first draft complete

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Finish poster, report, webpage, presentation slides for sponsor presentation (Steven, Sean)

  • Machine machine machine!

  • Presentation at sponsor on Thursday. If plate is in working condition, this would be good timing for setting up some cycle or heat testing.

  • Use results of presentation and cycle tests for last minute modifications in report. 

    • Is a Finals Week update of report and/or webpage okay to include possible testing at the end of Week 10?

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• • None.

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

• • Discuss machining methods with Tom and Isaiah.

    • Tom and Isaiah gave recommendations; Mark helped with fabrication.

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• Peer review of webpage:

  • Front page too cluttered with words; add more pictures everywhere; annotate pictures better

  • Make sure videos work;

  • Multimedia section entirely missing; Still need to add all the up-to-date CAD files and pictures

  • Peer review of report draft:

    • Mostly commentary on avoiding using certain phrases/words

    • Better, annotated pictures and CAD models should (and will) infiltrate the final report

Risks and Areas of Concern

• • Problem with tensioner placement discovered--mounting angles of tensioners had to be changed. Not sure of effect on performance.

  • CNC of base plate should take a good amount of time

Resources or Information Required but not Available

• • None.

Schedule

• • Describe upcoming milestone

  • Update Gantt chart.
