Final answer:
The statement is false as sheet metal operations include a variety of processes such as cutting, bending, forming, deep drawing, and stamping, beyond just pulling, pushing, and stretching.
Step-by-step explanation:
False, the most common sheet metal operations include more than just pulling, pushing, and stretching. They also encompass cutting, bending, and forming processes. Cutting involves shearing the metal to size, bending is about creating angles and shapes in the metal, and forming is a broader term that includes any manipulation of the metal's shape beyond flat. Operations like deep drawing, in which a sheet metal blank is formed into a cup or box-shaped structure, and stamping, where a die is used to shape the metal into a predetermined form, are also very common.
