1. A method for the quality assessment of a component produced by means of an additive manufacturing method, in particular a component for an aircraft engine, comprising the steps:
a) preparation of a first data set, wherein the first data set comprises absolute limit values that each characterize a maximum allowed range of values at an assigned component position of the component being produced; b) acquisition of a second data set by means of an acquisition device, wherein the second data set comprises actual values corresponding to the first data set, which characterize the assigned component position of the component produced; c) comparison of the first data set and the second data set by means of a computing device and
c1) classification of the component as being qualitatively fundamentally not OK if at least one actual value lies outside its assigned maximum allowed range of values; orc2) classification of the component as being qualitatively fundamentally OK if no actual value lies outside its assigned maximum allowed range of values; and if the component has been classified as being qualitatively fundamentally OK: d) preparation of a third data set, which comprises mean values that are determined from a plurality of actual values of the second data set by means of the computing device, wherein the plurality of actual values characterize an interrelated component region composed of a plurality of component positions; e) determination of at least one best-fit function that is dependent on the component geometry on the basis of the third data set by means of the computing device; f) determination of threshold values that depend on the component geometry by means of the computing device, wherein the threshold values characterize an allowed range of scatter of the actual values around target values predetermined by the best-fit function; g) checking by means of the computing device whether at least one actual value lies outside of the range of scatter characterized by the threshold values, and
g1) if no actual value lies outside of the range of scatter, the component is classified as being qualitatively OK; org2) if at least one actual value lies outside the range of scatter, then all actual values that lie outside of the range of scatter are compiled to obtain a fifth data set, and the component quality is assessed on the basis of the fifth data set and at least one predetermined quality criterion. |
