On your die project:
I can't believe that the semester is close to an end! The workload for this course was heavy. But I enjoyed teaching this course and I hope you enjoyed learning the materials of this course and the 5 projects you have had!
As you noticed from fixture project presentations, the designs were great and I am happy that you came up with so many good ideas for that relatively hard project that I assigned for you.
Anyway, for your last project remember that I have introduced two unknowns in the project just to keep you a little bit busier! (but not more than 5-10 minutes that I promised).
Remember that the diameter of the shell is 14 times the punch radius (there is a typo in project sheet and it should read "the punch radius" and not the draw radius). In fact d=14r. Start with finding r or the punch radius and after that everything will be easy (finding the punch radius should have been listed as number one task in the project).
You do not need to prepare this project in the form of a booklet. Just find the unknowns for the die drawing operation and then hand-sketch the die neatly. Use any of those die drawing designs we discussed in class. But remember to draw different parts according to the scale of the drawing. You can use this paper if you wish.
Let me know if you have any questions.
Happy die designing!

On your last test:
You can bring a formula sheet to the test (write just the formulas and not the facts!)
The drawing operation is either feasible or not feasible. In any case, go ahead and find other unknowns such as drawing force, blankholder force, etc.
And for hand-sketch, assume that the drawing can be accomplished anyway and consider the punch diameter and other values that you have found (This is just because of the limited time that you have).
