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.
