Abstract: A trim die for sheet metal or other materials is provided to trim the entire circumference of a drawn part. The trim die includes a trim plate with a connected trim punch moveably mounted in a stripper plate. Cam punches with cam lobes engage cam followers on the trim plate to impart motion to the trim die. The trim die of the present invention minimizes displacement of the part to be trimmed, including the excess material, and therefore is compatible with progressive dies. The corresponding method of trimming a part is also provided.

Abstract: Tooling and a method of employing tooling to produce beneficial stress waves in a substrate to provide high fatigue life structures. Stress waves are provided to work a substrate, causing dimples in the workpiece, along a uniform pressure profile in the workpiece. By use of the method, uniform beneficial residual stress is provided at surface and midplane apertures in a workpiece, so as to improve overall fatigue life. An improved tool shape is described, having a smooth curve, rather than a flat punch. Also, the use of a consumable wafer provides additional uniform stress profile benefits.

Abstract: Metal cold-working tooling and a method of employing such tooling. The tooling is used to produce deformation in a workpiece, to provide a selected beneficial residual stress profile in the workpiece, in order to provide high fatigue life structures in a minimum number of manufacturing steps. An indenter is used to coldwork a workpiece, causing dimples in the workpiece. Preferably, the dimples are provided with a shape formed by application of a uniform pressure profile to the workpiece surface. As optimized, a relatively uniform beneficial residual stress profile is provided at both the surface and at the midplane apertures in a workpiece, so as to improve overall fatigue life. Also, an improved indenter tool profile shape is described, having a smoothly curved indenter surface portion. And, the use of consumable lamina wafers provides the benefit of easy application of uniform stress profile to a workpiece.
