Summary The objective for this lab was for each individual to make a truck bed from a 1010 steel metal sheet. The individual would learn the process of bending the the metal, designing a shape based on dimensions, and shearing off parts that lack purpose in the design. This process of designing the truck bed takes time, precision, and carefulness. From this process one learns the basics of forming, and all the basic equipment required to create a truck bed.
Introduction Modern day manufacturing provides us with a vast array of metal forming processes to choose from. Sheet metalworking includes cutting and forming operations performed on relatively thin sheets of metal . Its most most commonly done as a cold working process

The sections of metal that could not be cut with the notcher were cut with hand held tin snips. Next, the stationary hole puncher was used to punch holes at each of the designated spots on the sheet metal totaling in eight punches. Each hole punched was approximately 0.188 inches, according to the schematic. The metal sheet is now ready to be shaped into a box. The first step in the bending process requires the outer shaded region of the metal sheet to be bent inwards at a 180˚ angle. In order the make it flatter you must safety roll the bent part. The process is repeated but instead of bending 180˚ the parts must be bent 90˚. The first section that must be bent is the welding side followed by the two adjacent sides. Before welding, a hand file was used to remove as much rust as possible from the sheet metal to ensure that a good weld is formed. Once the sides are bent and aligned as close as possible, the welding parts should be welded before bending the last side. When using the spot welding machine the user must wear gloves at all times and keep fingers and other items away from the welding nodes. After the welding is done and the last side is bent at 90˚ angle, the box must now have rivets placed in the sections where the metal has holes. First align the parts together so that the rivets go through both holes and create a
