Substitutive models of press deflections for efficient numerical die cambering

Abstract Cost and time for stamping die tryouts are significant within the car industry. A major contributing factor is that elastic deflections of dies presses usually not considered during virtual design forming simulation phase. Active surfaces only cambered based on previous experiences tool types presses. However, almost all unique, available valid new sheet materials. This leads to component deviations often several loops adjustments needed. Previously partners SMART Advanced Manufacturing research project CAMBER have developed advanced deflection measuring devices quantify deformations Using these measurements, cambering methodologies can be utilized in metal simulations. In this paper numerical substitutive press models described which capable compensating measured dynamics. The result show a compensated improve contact by over 80% compared corresponding without compensation.
