Press Working Press working may be defined as, a manufacturing process by which various components are made from sheet metal. This process is also termed as cold stamping. The machine used for press working is called a press. The main features of a press are: ·        A frame which support a ram or a slide and a bed, a source of mechanism for operating the ram in line with and normal to the bed. ·        The ram is equipped with suitable punch/punches and a die block is attached to the bed. ·        A stamping is produced by the downward stroke of the ram when the punch moves towards and into the die block. ·        The punch and die block assembly is generally termed as a “die set” or simple as the “die Press operations may be grouped into two categories Cutting operations Forming operations In cutting operations the sheet metal...

Tool and die makers are among the most highly skilled workers in manufacturing. These workers produce and repair tools, dies, and special guiding and holding devices that enable machines to manufacture a variety of products we use daily-from clothing and furniture to heavy equipment and parts for aircraft. Toolmakers craft precision tools and machines that are used to cut, shape, and form metal and other materials. They also produce jigs and fixtures-devices that hold metal while it is bored, stamped, or drilled-and gauges and other measuring devices. Die makers construct metal forms, called dies, that are used to shape metal in stamping and forging operations. They also make metal molds for diecasting and for molding plastics, ceramics, and composite materials. Some tool and die makers craft prototypes of parts, and then, working with engineers and designers, determine how best to manufacture the part. In addition to developing, designing, and producing new tools and dies, these worke...
