Method for obtaining design data, use of such a method, electronic computing device, computer program and computer readable medium

摘要

The invention relates to a method for determining design data for producing a forming tool. By means of an electronic computing device, a simulation is carried out in which it is simulated that tool parts of a tool move towards each other and are thereby moved into a closing position. The simulation simulates that by moving the tool parts into the closing position a workpiece is reshaped and thus transferred from an initial state to a first deformed state. The simulation simulates:that the tool parts remain at least temporarily in the closed state and thereby keep the workpiece in the first deformed state. The simulation simulates that the tool parts are moved away from each other. In the simulation it is simulated that as a result of moving the tool parts into the open position, the workpiece is automatically deformed to a second deformed state starting from the first deformed state due to internal stresses of the workpiece in the first deformed state (step S1).
