Abstract

A regulation method, corresponding device, and computer program product for the additive manufacturing of a component. The method includes: a) acquiring spatially resolved temperature data for a layer built up additively during the manufacture of the component; b) determining at least one region-of-interest on the layer, which is intended to be processed during the manufacture of the component; c) classifying temperature values of the region-of-interest; d) forming an average value of the classified temperature values; and e) controlling a processing device with the formed average value as the input value in order to process the layer.

Claims16

Dependent claims

A regulation method for the additive manufacturing of a component, comprising:

a) capturing spatially resolved temperature data relating to an additively constructed layer during the manufacturing of the component,
b) determining at least one region of interest of the layer which is intended to be processed during the manufacturing of the component,
c) classifying temperature values of the region of interest,
d) forming a mean value of the classified temperature values, and
e) controlling a processing device with the formed mean value as an input value in order to process the layer,
wherein the processing apparatus is an induction heating apparatus for preheating the layer and comprises a regulation system which receives the mean value as an input value.
