The main purpose of deep drawing is to create hollow metal pieces for various applications. So the answer is (a).

Deep drawing is a metal forming process in which a sheet metal blank is drawn into a die cavity to form a cup-shaped or cylindrical part. The process is used to manufacture a wide variety of parts, including beverage cans, food cans, automotive parts, and electronic components.

In deep drawing, the metal sheet is held between a punch and a die. The punch is a shaped tool that presses the metal into the die cavity. The die cavity is shaped to form the desired part.

As the punch presses the metal into the die cavity, the metal flows inward from the periphery of the die hole. The metal is prevented from necking and breaking by the pressure of the punch and the friction between the metal and the die.

The depth of draw is the distance that the metal is drawn into the die cavity. The depth of draw is limited by the strength of the metal and the friction between the metal and the die.

Deep drawing is a complex process that requires careful control of the process parameters. The process parameters include the punch force, the die pressure, the friction coefficient, and the temperature of the metal.

Deep drawing is a versatile process that can be used to manufacture a wide variety of parts. The process is relatively inexpensive and can produce high-quality parts.
