ABSTRACT:
A fixture for supporting a workpiece such as a cast turbine blade allows bending and/or twist correction of the workpiece with the movable ram of a press. The fixture includes a base and a pair of workpiece supports mounted at spaced locations on the base. A bearing such as a spherical swivel bearing is included in each workpiece support. Each bearing has a mount receiving a portion of the workpiece therein. When the workpiece is supported by the bearing mounts along a support axis, and is engaged by the press ram intermediate the workpiece supports for bending correction, the bearings and workpiece can move in at least one plane including the support axis. Preferably, the bearings also allow rotational movement about the support axis, while a rotation imparting member allows twist correction by rotational movement of one bearing and the workpiece portion therein with respect to the other bearing which is restricted from rotating.
