ABSTRACT:
A method of manufacturing a turbine blade retainer using a material cutting device and a material bending device includes steps for suspending a bar stock material between a polyurethane shock absorber and a bore of a cutting jig support, moving the cutting punch downward to press the distal end of the bar stock material into the shock absorber and then cut the bar stock material to thereby generate a blank, clamping the blank between a bending punch and a receiving slide by pressing the bending punch against the receiving slide, bending the distal end of the blank against a chamfered section of a bending support in response to continued downward motion of the bending punch to thereby form a blade retainer precursor, and milling the blade retainer precursor to form the blade retainer. Corresponding devices for performing these steps are also described.
