Trim Optimization
Stampack includes the ability to automatically develop the blank outline by using the trim line optimization tool. It is an essential tool for the determination of optimum blank shapes and trimming lines. The trim optimization tool automatically adjusts the blank outline to remove or add material until the desired final part boundary is achieved. Simulating for trim optimization not only prevents the wastage of material, but also reduces the product development period, improves product quality, and reduces occurrence of defects like wrinkling and tearing.
Especially for multi-station processes, trimline optimization delivers significantly better results than approximations given by any “one-step” solvers which do not simulate incrementally.
Thick Deep Drawn Parts
With thick drawn parts, material thickness of the part can vary as you add or remove material to the blank outline. This makes determining initial blank outlines very time consuming to preform by hand or in the shop. With Stampack you can even optimize for either the inside, midplane, or outside edge of the material in order to have the correct part geometry after optimization.
Large Panels
For large panels and mid-sized parts, finding the optimized blank outline in the simulation can have large savings for the strip width when accurate outlines are known.
Optimizing Coined Geometry
Trim Optimization can even be run on parts that include coining and ironing. This can lead to additional savings by creating high accuracy cutting punches, which can completely remove the need for secondary trim stations after part forming.
