Abstract
A method of manufacturing a part having a beveled edge with a serration formed in the beveled edge. The method includes positioning a part between a first die piece and a second die piece; and moving the first die piece relative to the second die piece. The movement results in both shearing a portion of the part to create the beveled edge, and serrating the beveled edge to create the serration.
Claims11
A method of manufacturing a part having a beveled edge with a serration formed in the beveled edge, the method comprising:
- positioning a part between a first die piece and a second die piece;
- and
- moving the first die piece relative to the second die piece, the movement resulting in both shearing a portion of the part to create the beveled edge;
- and serrating the beveled edge to create the serration;
- wherein moving the first die piece relative to the second die piece includes moving the first die piece at an oblique angle relative to the second die piece, the oblique angle defining a bevel angle of the beveled edge;
- and
- wherein the second die piece includes a plurality of projections configured to form the serration in the beveled edge, and wherein moving the first die piece relative to the second die piece creates a compression force between the part and the plurality of projections such that the serration is formed by displacing material of the part.
