Warpage

Term generally applied to distortion that results during quenching from heat-treating temperatures; hand straighteningA straightening operation performed on a surface plate to bring a forging within the straightness tolerance. Frequently, a bottom die from a set of finish dies is used instead of a surface plate. Hand tools used include mallets, sledges, blocks, jacks, and oil gear presses in addition to regular inspection tools.... More, pressA machine tool with a stationary bed and a slide or ram that has reciprocating motion at right angles to the bed surface; the ram is guided in the frame of the machine. straightening, or coldFaults produced in a forging by incorrect tool design or incorrect flow of steel that results in the formation of a crack in the forging surface. restriking is employed, depending on the configuration of the part and the amount of warpageTerm generally applied to distortion that results during quenching from heat-treating temperatures; hand straightening, press straightening, or cold restriking is employed, depending on the configuration of the part and the amount of warpage involved. The condition is governed by applicable straightness tolerances; beyond tolerances, warpage is defect and cause for rejection. The term is not to be confused with "bend" or "twist."... More involved.
