Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Race design mostly complete, FEA analysis complete
Third iteration of follower design in progress
rollers removed due to hole causing high forces from deformation
Wishbone profile to allow for two flexing prongs requiring lower forces for displacement
Operator redesign mostly complete, with issues in need of resolution
Dovetailed rails - friction? potential jamming due to offset force? debris catching in rail?
Plunger - torsional force acting on push rod?
Spring placement?
Accomplishments from Previous Week
Completed proof of concept
FEA of races proving reduced displacement
Initial FEA and material selection of follower
Motion study of operator design
Established potential, simpler redesign of operator (increased plunger and weight size)
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Complete preliminary review (Thursday, 5/21)
Finalize follower design
Complete and submit second draft of report and website
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Mike Goldin (Zoom, 5/15): while the necessary redesign of the operator is a lot simpler than the operator design (which, while properly accounting for force vectors, may struggle with friction), it might be nice to keep that design in the background
Action - planning on meeting w/ Dr. Ghazi to explain the situation
In the meantime we're still working on the operator design just so we have it
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Dr. Ghazinejad (Zoom, 5/14) - define materials and manufacturing method of follower; use a plastic v-shaped spring between halves
Rishabh Khanna (Zoom, 5/16) - make sure that design parameters and deliverables are well quantified
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Risks and Areas of Concern
Operator design - it seems that each iteration of the operator creates more issues than the last. We need to meet with Mike more.

Progress on Report and Webpage
Report is about 65% complete? We still have quite a bit of work to do and revisions are necessary in some areas
Website updates: Week 7, added some files to the CAD and internal restricted files, plan to update the front page
