Meeting 2007.04.03 Analysis

From Teamnumber1

2.72 - Team Number 1
Group Meeting
April 3, 2007

• Short-term To-do List:
  • Marcus --> Get the new dimensions from the updated Solidworks files for HTM analysis
  • Ani & Martin --> elastic errors
  • Will & Dan --> Talk to Dave & Pat about rake angles on aluminum
  • Will & Dan --> Code (MATLAB or MathCAD) to take in cutting force and output bearing load and shaft stresses
  • Meet Thursday after class to discuss progress!

• Long-term To-do List:
  • Spindle Shaft design & bearing selection & consideration of collet
  • Structure design & construction
  • HTM's for elasticity
  • Feasibility of Accuracy = 10 microns
  • Straightness values for threaded lead screw
  • Rail analysis & bushing selection
  • Drive system

• Considerations (to keep in mind):
  • Should use our HTM analysis, lead screw straightness, to evaluate feasibility
  • Drive Train:
    • If using gears or chains - must have a clutch
    • Belts with a "Christmas Tree?" - belts allow slipping at a dangerous torque!
    • Contingency (Direct Drive)
    • Bearings for driver
  • Will have to sit down with Prof. Culpepper & Chris to design the flecture
