Abstract
The invention relates to a method for determining the geometry of a raw part, which is shaped to form a finished part in a hydroerosive grinding method, comprising the following steps: (a) creation of a structural model of the finished part to be produced, the structural model of the finished part to be produced being used as an initial model for the first execution of the next step (b); (b) mathematical simulation of the hydroerosive grinding method, with which an intermediate model with a modified geometry is produced starting from an initial model; (c) comparison of the intermediate model produced in step (b) with the structural model of the finished part and determination of the distance, orthogonal to the surface of the structural model of the finished part, between the structural model of the finished part to be produced and the intermediate model at each node of the structural model, and comparison of the orthogonal distance with a predetermined limit value; (d) creation of a modified model of the component by adding from 5 to 99% of the distance determined in step (c) with the opposite sign at each node on the surface of the model which is used as an initial model in step (…
