ADVANCED MANUFACTURING PROCESSES (B) – 5 Credits Prof. Mateo Strano Exam 29.01.2024 Politecnico di Milano Simple numerical ques�ons Companies A, B, C and D are compe�ng with each other. They manufacture small metal automo�ve parts (nuts, bolts and washers) by conven�onal metal forming processes (cold forming). Their produc�on can be divided in families or groups (e.g. dented washers, threaded screws with flat head, etc.). Each family is made of several different dimensional items. Every item requires a different metal forming tool set. All of the parts are made of low alloy, heat treatable steel. Numbers are in the table atached. The companies use EDM or conven�onal machining to manufacture their metal forming punches and dies. They heard about innova�ve applica�ons of Rapid Tooling and Addi�ve Manufacturing. QUESTION 1 Which one of the four companies requires a technological solu�on more oriented to mass produc�on? - A - B - C - D - None of them Explana�on: QUESTION 2 0 50000 100000 150000 200000 250000 300000 350000 400000 450000 0 50 100 150 200 250 300 350 average yearly volume per item # of items mass production highest flexibility ADVANCED MANUFACTURING PROCESSES (B) – 5 Credits Prof. Mateo Strano Exam 29.01.2024 Politecnico di Milano Which one of the four companies requires a technological solu�on more oriented to mass customiza�on? - A - B - C - D - None of them QUESTION 3 Which one of the four companies requires the most flexible technological solu�on? - A - B - C - D - None of them QUESTION 4 Which one of the four companies might start considering the use of polymer rapid tools in their metal forming opera�ons? - A - B - C - D - None of them Explana�on: they all do metal stamping opra�ons at high volumes, impossible to use low quality tools, except maybe for…
