Lab Schedule

Do NOT email your labs to Professor Provancher, make arrangements with one of the TAs if you are not able to hand your lab in to the ME 4000 basket in the ME office.

• Lab 0

• Lab1
  • Note that it is assumed that radius on the right and left sides of the part are 20mm and are centered on the right and left sides of the part respectively.
  • Also note that it is not required to turn in a dimensioned drawing for lab 1, simply a printout of your completed part that will make it unambiguous to the TAs that you modeled your part correctly. However, I would recommend turning in a dimensioned drawing for practice, since the next several labs will require you to turn in a dimensioned drawing.
  • For lab 1, rather than modeling the part on page 2, you are welcome to model a part that’s relavent to your project (with 2 caveats).
    1. The part you model must be as complex as the part on p. 2 of the assignment
    2. Please do something new, i.e., please don’t hand in a drawing you did freshman year. =)
  • ProE information and tutorials

• Lab 2

• Lab 3: Fits & Tolerances - The spindle and hub revisited
  • When you specify your \”fits\”, you can do this by specifying the fit (e.g., h6) after the dimension and use a tolerance block in the lower left corner of your drawing as a note OR you can display the proper tolerance numerically after the dimension.

  • To display 1, 2 or 3 decimal places following a dimension
    • right click on the drawing background and select \”properties\”
    • click \”Drawing Options\” in the menu window on the right side of the screen.
    • in the \”Drawing Options\” window, scroll down to the section titled \”These options control dimensions\”
    • scroll down a bit further to \”lead_trail_zeros\”
      • Select \”both-english\” from the pull-down bar (currently set at \”none\” I believe). This is why Pro E displays 68 for a dimension on your part.

  • To display tolerances after your dimension
    • right click on the drawing background and select \”properties\”
    • click \”Drawing Options\” in the menu window on the right side of the screen.
    • in the \”Drawing Options\” window, scroll down to the section titled \”These options control dimensions\”
    • scroll down a bit further to \”tol_display\”
    • select \”yes\” or \”on\”

  • To specify tolerances after your dimension
    • Select the dimension (it will highlight in red).
    • right click the dimension, and click properties
    • you’ll see an entry cell for your tolerances (and a pull down menu above that which allows you to chose various tolerance display schemes).

• Lab 4 Due Monday Oct 10th by 5pm (not Sept. 10th):

This lab teaches two advanced modeling techniques - sweeps and blends. Both techniques are highly useful as they closely resemble manufacturing processes such as bending, forming, forging, etc.

• Lab 5: (Lab held in EMCB 102).
  More sketching and brainstorming Please attend if you can.

• Lab 6: Advanced Modeling Through Importing Complex Datum Curves

• Lab 7 :
  This lab involves designing a hoist structure by producing stress and deflection results via FEA and comparing these results to analytical solutions.
  • Please include the amount of time it takes you to complete this lab, when you turn it in.

• Lab 8:

• Lab 9: Finite Element Analysis of a Pin Joint

• Lab 10 (unlikely): Contact Stress Analysis (via FEA and hand calcs).

• Lab 11 (unlikely): Tool path planning
