You are a quality control engineer at the Alief Premier Forging Company, and one of your jobs is to oversee the forging process. (a) If the unknown raw billet (5 cm in diameter) displayed a true stress and true strain curve shown in the figure, based on your learning in DfM, identify the most likely material from the supplier according to the parameters listed in the DfM lecture. (Must show mathematical proof of your answer.) (10 points) True Compressive Stress (MPa) 1000- 900- 800- 700- 600- 500- 0.01 0.1 1 10 True Compressive Strain (mm/mm) (b) Based on the data in the graph, what is the FORCE (N) required to upset a billet to 60% of its ORIGINAL HIGHT? (Neglecting the influence of friction and the barreling effect.) (10 points) (c) Assuming that the final forged product is a disc washer that has a center hole without webbing, and the final product dimension is 12 cm (OD) x 6 cm (ID) x 2 mm (height). Assuming that the cost of raw material is $5.10/kg, determine the material cost for a forged washer. [Hint: (1) Follow the unit in the slides, cm $\rightarrow$ mm. (2) Consider the hold for the perimeter. (3) There is one value missing, and you need to suggest a value based on results in (a) and (b) and provide the source of the value.] (20 points)
