A numbers of sheet metal forming processes such as shearing, bending, stretch forming, deep drawing, stretch drawing, press forming, hydroforming etc. are Toggle navigation. About us · Courses · Contact us · Courses; Mechanical Engineering; NOC:Principles of Metal Forming Technology (Video); Syllabus Because the quality of the edges of the sheet may affect sheet-metal-forming operations, edge defects in rolled sheets often are removed by shearing and Tools include punch, die that are used to deform the sheets. Classification of basic sheet forming processes. Bending. Deep drawing shearing. Page Inderdeep Singh, Department of Mechanical & Industrial Engineering, IIT Roorkee.
