1.	Which of the following manufacturing processes operates under the influence of external forces?(a) Metal forming(b) Powder metallurgy(c) Casting(d) WeldingThis question was posed to me during an interview.The above asked question is from Classification of Metal Forming Processes in chapter Forming Process of Casting-Forming-Welding II
Answer» RIGHT option is (a) Metal forming Explanation: In the metal forming process, the raw MATERIAL is CONVERTED into a desired shape by the APPLICATION of external force. The metal work piece is subjected to plastic deformation which results in changing of shape and size of the work piece or specimen under the influence of external forces or stresses.
