Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Guide Rail Design: Mostly finalized -- 8020 T-slot profile part # 40-4080
Drive System: Timing Belt Drive
Sensor: Incremental Optical Rotary Encoder (HKT22)
DAQ: Arduino and LabView
Accomplishments from Previous Week
Measured Dove-Tail size, actual carriage size
Took additional photos of existing system
Quotes on pillow block bearing, guide rails, stepper motor, encoder, non-magnetic ball bearings
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Finalize parts and order
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Verified Translation Distance: 64 cm +/- 10 cm
Leave Stepper Motor on at all times: OK
LabView: Sponsor needs to confirm with IT, but believes licensing should be no problem
design considerations
avoid looping wires
prevent getting things caught in the system (and safety)
emergency and/or automated stop
wider table for additional work space
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Look into V-grooves
$100/ft
Minimize constraints
Fixed and Floating Bearing Design
Fixed Bearing and Wheel Bearing Design
Single Guide Rail Design (V-groove or 8020 profile)
Look into motor driver with current signal to shut off power
Get quotes on guide rails -- typically pretty expensive
SRA08CC-048.000 -- $528
CCR08-048.000 - $400
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
What about a hydraulic system? If you know the amount of fluid pumped into the hydraulic ram you can know very precisely how far the ram has moved.
More clarification is needed for the DC motor test slides.
Research availability of 2-way pneumatic and spring return cylinders
Is position tolerance constrained in one axis only or in three?
Look at systems used in bed of CNC mill
Figure out what material will disrupt the image of the MRI as soon as possible
Note the budget for the project
Potentially 3D print a plastic lead screw
Look into linear actuators/controllers made by the maker of Labview NI if using Labview
Improve on drawings and diagrams, including 2D and 3D for concepts
Risks and Areas of Concern
Anti-Crashing Technology
Confirm LabView laptop?
Resources or Information Required but not Available
NEMA stepper motor power-torque plot
Schedule
Finalize design, order parts, and built system
Update Gantt chart.
Budget (list amount spent and amount remaining)
$0 spent out of $1500
