Draft

The necessary taper on the side of a forgingThe process of working metal to a desired shape by impact or pressure in hammers, forging machines (upsetters), presses, rolls, and related forming equipment. to allow removal from the diesThe metal blocks into which forging impressions are machined and from which forgings are produced.; also applies to the die impressionThe portion of the die surface that shapes the forging.. Commonly expressed in degrees as the draft angleThe angle of taper, expressed in degrees (usually 5° to 7°), given to the sides of the forging and the side walls of the die impression.. As applied to open die forgingForging worked between flat or simple contour dies by repeated strokes and manipulation of the workpiece. Also known as "hand" or "smith" forging. See Open-Die Forging., draftThe necessary taper on the side of a forging to allow removal from the dies; also applies to the die impression. Commonly expressed in degrees as the draft angle. As applied to open die forging, draft is the amount of relative movement of the dies toward each other through the metal in one application of power.... More is the amount of relative movement of the diesThe metal blocks into which forging impressions are machined and from which forgings are produced. toward each other through the metal in one application of power.
