PROCEDE ET DISPOSITIF SERVANT A GENERER DES ENSEMBLES DE DONNEES DE COMMANDE POUR LA FABRICATION DE PRODUITS PAR COULEE SANS MATRICE ET APPAREIL CONCU POUR FABRIQUER CE GENRE DE PRODUITS
The invention relates to a method, which is used to produce sets of controldata for the production of metallic and/or non-metallic products 2, 21 byfree-form sintering and/or melting by means of a high-energy beam (8), inparticular a laser beam or electron beam, whereby a product 2, 21 is builtup, layer by layer 12 to 15, 20, 22, out of a material 6 that is to be spreadout in layers, by means of said beam 8, which is guided with the help of acontrol data set, whereby the method comprises the steps of loading 23 aproduct target geometry data set that represents the target geometry of theproduct to be produced and of generating 25 the control data set on thebasis of the product target geometry data set. To improve the dimensionalaccuracy, this method comprises the additional steps of determining 24 acompensation data set and/or a compensation function to compensate formanufacturing-related effects caused by the sintering and/or melting and ofcombining 25 the compensation data set with and/or applying thecompensation function to the product target geometry data set to generatethe control data set.The invention further relates to a corresponding device (11) to carry out saidtype of method as well as a correspondingly controlled apparatus (1) forproduction of said type of products 2, 21.
