Method for automatically adapting at least one adaptable process parameter of a tooling machine such as a milling and/or turning tool, the tooling machine being part of a first or second manufacturing process for physically processing input work pieces into output work pieces. According to the method, at least one geometric feature of an output work piece is measured by a coordinate measuring machine, the geometric feature being a direct or indirect result of the processing with the tool. The measurement result is together with nominal measurement data of the geometric feature fed into a deterministic digital simulation of at least a part of the manufacturing process with a digital model such as a digital twin of the tooling machine and modelled process parameters, therein the adaptable process parameter of the tooling machine, simulating at least a deterministic behavior of the tooling machine relevant for an operation of its tool. The simulation is executed with varying of at least one of the modelled process parameters with the objective to emulate the measurement result. From the simulation with thus adapted modelled process parameters and based on nominal geometric data of the feature an adapted value for the adaptable process parameter is derived which enables an adapted operation of the tooling machine with respect to its tool resulting in a reduced difference between real and nominal geometric data of the feature.
