Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Support frame and load frame metal has arrived
Motor, motor controller, motor plate has arrived
Start fabrication of components that need fabrication
Still tweaking design for the best method of fastening parts together
Accomplishments from Previous Week
Finished machining C-beams and began cutting parts -Jorge Sergio
Updated motor mount design to allow for adjustment of motor in x direction -Brandon
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Find lubricant and lube-gun for the pillow blocks - Jerry
Finish design on safety cage - Jerry
Finish preparing parts for assembly- Jorge Sergio
Need a laptop with Labview for motor controller programming - Jerry
Pulley size and length needs to be determined - Brandon
Update parts list for motor assembly - Brandon
Purchase 6061-T8 Aluminum tube from DX Engineering - Jerry

Bearings and tube tolerance
Oversize bearings, loose fit of tube and bearings
Machining an h7 shaft tolerance = ask Tom
Maybe use a collar within a collar, or a shim
Motor mount cantilever
Should add additional supports that can make fine adjustments on the position and angle of motor mount plate
Tom Chalfant and Isaiah Freerksen (in person, 5/7/2012)
Bearings and tube tolerance
Machining an h7 shaft tolerance over the entire length (6ft) of tube = very difficult to accomplish, not worthwhile for multiple tubes
Able to machine near h7 for ends
Consider only one bearing to fix tube axially
Maybe use a shim to close the gap between bearing ID and tube OD

Risks and Areas of Concern
Motor mount plate was not designed to move the motor axially but transversely
Resources or Information Required but not Available
6061-T8 Aluminum Fatigue testing data
Schedule
Upcoming Milestone
Complete fabrication of the support and load frame
Pillow blocks arrive, are mounted, and are lubricated
Safety Cage design finalized
Motor is wired up and tested
Motor controller is tested with motor
Update Gantt chart.
Budget (list amount spent and amount remaining)
$1158.12 spent
$841.88 remaining
Progress on Report and Webpage
Report critique from professor has been received and will update report soon
