We investigate the manufacturing of various metal parts to be produced by metal casting and molding. For each part, indicate which molding process is the best.

Note. Your answer will be considered as correct only if you choose the best process for each application. A process that could be used but which is not the best among the different propositions is a wrong answer.

In orthogonal cutting, the shear plane angle depends on the friction coefficient of the material being cut as the chip slides on the tool.

We would like to manufacture a curved pipe like illustrated below.

We assume the pipe inner diameter is 20 cm and that the pipe should be made of cast iron. Furthermore, we plan to produce up to 50 of these pipes.

Which molding process would you recommend?

What are the possible observations that can be made during and after a machining operation if a discontinuous chip is produced?

We would like to manufacture a curved pipe like illustrated below.

The 2D Fourier transform (2D FT) is a useful tool when dealing with surface analysis. Select all the correct statements.

Let us consider a beam of fixed length with square cross-section of area . It is loaded at its tip with a point force . What is the ratio to optimize in order to minimize the mass and achieve the maximum strength in bending?

Reminder. Elementary equations for uniform rectangular beams subjected to bending:

• Bending moment:
• Section modulus of rectangular beam of width and height :

These pictures represent various concrete surface profiles (CSP) after specific machining operations. We assume that the scale is the same for the four images. The viewing windows are 8 x 4 microns (width x height).

Please assign the best illustrative image among the four above to the following descriptions: (a given picture might be assigned multiple times; only one possibility per description)

Select the most accurate statement that best describe the Ashby method.
