Industrial art of manufacturing stamping dies, plastics molds, and jigs and fixtures to be used in the mass production of solid objects. The making of dies for punch presses constitutes most of the work done in tool and die shops, and most such pressworking dies are used in the manufacture of sheet-metal parts such as the panels of an automobile body.
Mold
In biology, a conspicuous mass of mycelium and fruiting structures produced by various fungi . Molds of the genera Aspergillus, Penicillium, and Rhizopus are associated with food spoilage and plant diseases, but some have beneficial uses, as in the manufacture of antibiotics and certain cheeses. Neurospora, or orange bread mold, has been invaluable in the study of biochemical genetics. Water molds live in fresh or brackish water or wet soils, absorbing dead or decaying organic matter.
jigs and fixtures
Components of machine-tool installations, specially designed in each case to position the workpiece, hold it firmly in place, and guide the motion of the power tool . Jigs can also be guides for tools or templates, as in the furniture industry. Special cramping jigs that ensure squareness are set up so that, for example, a wardrobe can be glued up in one operation by power-driven rams.
punch press
Machine tool that changes the size or shape of a piece of material, usually sheet metal, by applying pressure to a die in which the workpiece is held. The form and construction of the die determine the shape produced on the workpiece. A punch press has two components: the punch, which is attached to the reciprocating ram of the machine; and the die, which is clamped onto a bed or anvil whose flat surface is perpendicular to the path of the ram. The punch pushes against the workpiece, which is held in the die. Punch presses are usually driven by electric motors.
