Give an example of why the functional specification must also include some idea of the production volume.

What will be an ideal response?

Question 2

Define simultaneous engineering, and point out a problem that might arise if it is not done.

Answer to Question 1

One of the design criteria that must be met is economics. In most molding processes production volume is critical for determining the cost. For instance, in the injection molding process, the size of the mold can mean a difference of tens of thousands of dollars in mold cost. These mold costs are part of the overhead which must be absorbed in the price of the part.

Answer to Question 2

Simultaneous engineering is the concurrent development of the part design and the process design. A problem that could arise if they are not done at the same time is that a part is designed that would be very difficult to make, where with just a minor recognition of the capabilities of a process, the design could be changed and the problem avoided.
