Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Design: Completed
Fabrication: Completed
Analysis: Completed
Tests: Mostly Completed
Completed repeatability, accuracy, resolution, current sensing testing
Need to perform test run in magnet room for magnetism, operation
Accomplishments from Previous Week
Repeatability and Accuracy testing
repeatability: +/- 0.025mm, no backlash
accuracy: +/- 0.25mm, backlash
Calibration of resolution
1 step = 0.057mm
Stall torque analysis for different speeds and amperage
Current sensing analysis
Landmarking option incorporated into GUI
GUI interface finalized
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Connect fiber optics to PCB (Alex)
Connect optical sensors to circuit (Brian)
Machine covers for pulleys and motor (Ola)
Machine box for electronics, incorporate shielding (Sally)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
"Save Position", "Saved Position" = "Set Landmark", "Landmark"
incorporated landmarking to denote target location on sample
separate "save position" option to denote adjusted position from isocenter
Calibrate steps in terms of distance
created sub-VI to translate stepper counts into millimeters
Sample positioning with laser to establish fixed distance to move to home, isocenter
Don't want to operate without being right next to the system (at least in the beginning)
suggest future designs for enabling position in magnet room
Only need to move relative distance
GE system: switch with metal pin to indicate "home"
created relative "home" position
Would be nice to eliminate unnecessary motion when positioning
Can use ruler by system; sight along ruler and input as "home" in GUI
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Think about how to show moving to the same area on video
single run video using fine adjustment and returning to saved position
Think about what you need to show on the final presentation, poster, etc
Coordinate time for sponsor presentation
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Risks and Areas of Concern
Integrating PCB, fiber optics, and optical sensors
Current sensing sensitivity, reliability
Resources or Information Required but not Available
Schedule
Describe upcoming milestone
Update Gantt chart.
Budget (list amount spent and amount remaining)
Total budget: $1500
$827.65 spent, $672.35 remaining
Progress on Report and Webpage
Report: mostly completed, need to add instruction manual
Webpage: uploaded more pictures, videos; need to upload code
