Examples sheet metal formed. 16 kalpakjian design for sheetmetal working ch. Ongoing miniaturization in various technical fields such as the electronics industry or micro systems technology requires precise forming processes for the production of small and thin components. M p groover fundamentals of modern manufacturing 3 e basic types of sheet metal processes 1.

Bending straining sheet around a straight axis 3. Both the die and the punch have shape of the part to be manufactured. Or in other words drawing is the operation of producing thin walled hollow shaped parts from sheet metal. Cutting shearing to separate large sheets blanking to cut part perimeters out of sheet metal punching to make holes in sheet metal 2.
