1.	Which of the following processes of metal forming is best suited for making products like aircraft wings and window frames?(a) Forging(b) Rolling(c) Drawing(d) Stretch formingI have been asked this question in examination.I need to ask this question from Stretch Forming topic in section Miscellaneous Forming Processes of Casting-Forming-Welding II
Answer» Correct option is (d) Stretch forming To explain: Stretch forming is a sheet metal forming process in which the sheet metal is clamped at the edges and stretched by USING the dies or form blocks. And no any lubrication is required significantly during the process. This method is BEST suited for MAKING the PRODUCTS LIKE aircraft wings, window frames, automobile door panels etc.
