• Lab 10 wraps up the CAD laboratory sequence with tutorials on CAD Animation and Finite Element Analysis of a Pin Joint

• Lab 9
  • This lab involves designing a hoist structure by producing stress and deflection results via FEA and comparing these results to analytical solutions.

• Lab 8

• Lab 6

• In Lab 7 you will learn advanced Modeling Through Importing Complex Datum Curves

• Lab 5

• Lab 4

• Fits and tolerances lecture

• Main/Lab4

The purpose of Main/Lab4 is to give you practice with assemblies and drafting and to think about practicalities of designing mating parts. You will be reminded of the basics of fits and tolerances at the beginning of the lab session, but you can also refer back to the lecture given on this topic back in ME3910.

• ME3910 Lectures
  • Fits and tolerances lecture

• Lab 3: Sketching II
• This lab emphasizes:
  • More sketching and exploring your design project (including brainstorming).
  • Come to class with a project (\”your thing\”) idea in mind… some part of your project that is composed of at least two mating parts. If you don’t have something in mind, the TAs and Prof. can help you come up with something. Make sure to coording
• No CAD tutorial this week

• Lab 2 has been posted.

• Lab 2 has been posted.

• SolidWorks information and tutorials coming on the Lab2 page

General Content:

• Sketching and brainstorming

• Lab 1 information and handouts are here.

General Content:

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. However, they are not obligated to do this for you, so tread lightly.

• lab 2 will be similar to Lab1 from last year, but will also include some basic drawing formatting and tolerancing.
  • 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.
  • For lab 2, rather than modeling the example part in the assignmet, 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
  • SolidWorks information and tutorials coming…

• Lab 3: Sketching II will be similar to Lab 5 from last year.
• This lab will emphasize:
  • More sketching and brainstorming as applied to your individual design project.
  • Come to class with a project idea in mind… some part of your project that is composed of at least two mating parts. If you don’t have something in mind, the TAs and Prof. can help you come up with something.
  • ProE information and tutorials
  • SolidWorks information and tutorials coming…

• Lab 4 will be posted in the coming weeks, but will be similar to combining Lab 2 and Lab 3 from last year.

• From last year’s 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 ProE 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 5 will be similar to Lab 4 from last year.
  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.
  • include a screen shot of your part’s feature hierarchy to show that the part was constructed via sweeps and blends.

• Lab 6
  • In Lab 6 you will take 2 or 3 of the most promising concepts that you sketched up for Lab 3 and create solide models and assemblies.
    • By drawing out these concepts in more detail and scaling them to the required size and using COTS parts with your assemblies it will help you to understand if your designs are feasible.
    • Provide a short writeup of the design & function of each concept
    • Formatted drawings of these are not required, screen shots are fine

• Lab 7 will be similar to Lab 6 from last year: Advanced Modeling Through Importing Complex Datum Curves

• Lab 8

For Lab 8 you’ll show your design trade and final formated and toleranced assembly drawing of your individual design project, along with any supporting information you used to help make this decision.

• Lab 9 will be similar to Lab 7 from last year:
  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.
