A method of manufacturing a press-formed article includes first press forming and second press forming. In the first press forming, an intermediate formed article is formed from a metal sheet by subjecting the metal sheet to processing including performing draw-forming on the metal sheet to form a peripheral wall portion, bending the metal sheet to form a convex flange portion, and bending the metal sheet to form at least a side standing flange main body portion of a side standing flange portion and a floor flange main body portion of a floor flange portion. The second press forming includes bending the intermediate formed article to form the convex flange portion to an inclined flange portion.

The present application provides a deformation correction system for a hot gas path surface of a turbine shroud. The deformation correction system may include a first die having a curved surface and a second die such that the hot gas path surface of the turbine shroud is positioned between the first die and the second die.

A method for rerounding a tubular structure includes the steps of: (1) inserting the tubular structure into a rerounding tool that is in an open position, the rerounding tool having a first block with a first semi-circular trough formed therein in a first surface thereof and a second block with a second semi-circular trough formed therein in a second surface thereof, the tubular structure being laid within the first trough; and (2) closing the rerounding tool by bringing the first surface into contact with the second surface such that the tubular structure is also received within the second semi-circular trough resulting in rerounding of the tubular structure due to the first semi-circular trough and the second semi-circular trough defining a cylindrical cavity.

In the straightening of radial run-out faults or linearity faults on elongate workpieces having at least one toothed region having peaks and troughs of the teeth of said toothed region, such as on toothed shafts or toothed racks, for ascertaining deviations from the ideally straight workpiece, the locations of the surfaces of the not yet straightened workpiece that form a reference plane are scanned at least at points or in portions on or in the region on the active reference circle or pitch circle, respectively, of the toothing that lies between the peaks and troughs of the teeth. The resulting measured items of data are utilized by the straightening machine such that a workpiece that is as ideally straight as possible at least in the toothed region is achieved by the straightening. The elevated locations of the tooth heads of the toothed region that form the peaks of the teeth and the elevated locations of neighboring tooth surfaces that lie in the reference plane are detected, and the height differentials of the elevated locations of the tooth heads in relation to the elevated locations of neighboring tooth surfaces that lie in the reference plane are ascertained. The height differentials are utilized by the straightening machine as corrective measured items of data such that said height differentials are considered when straightening the workpiece so as to form a workpiece that is as ideally straight as possible in the reference plane.
