Method for separating cast parts from clusters obtained by means of casting processes, the cluster comprising a pouring cup, cast parts attached to the cluster through attachment elements (15b, 15c) and feeding risers (16a, 16b), characterized in that it comprises: a) defining a first spatial reference system (X, Y, Z) for a first computer vision system, defining a second spatial reference system (X',Y',Z') for a first industrial manipulator in a second working area where the cast parts are separated by means of a separating system, and interrelating both spatial reference systems according to the distances (x,and,z) separating them and the orientation of each axis; b) developing a basic programming algorithm for the first industrial manipulator based on movement instructions through parameters; c) storing data corresponding to the cast parts, feeder lines (15a, 15b, 15c) and risers (16a, 16b) of the clusters, comprising data of the cutting points for cutting the cast parts from the cluster; d) placing the cluster in a first working area; e) obtaining an image of the casting cluster by means of the first computer vision system; f) processing the image of the cluster obtained by the first computer vision system in phase e) to obtain the orientation of the cast parts and the coordinates of the cutting points according to the data of the image of phase e) and the data stored in c); g) converting the coordinates of the cutting points and orientation of the parts of the first spatial reference system (X, Y, Z) of the first computer vision system to the second spatial reference system (X', Y', Z') of the first industrial manipulator; h) determining the entering angle for separating each cast part based on reference entering angle values contained in a database in computer equipment; i) transmitting the coordinates and orientations calculated and the entering angle of phase h) to the first industrial manipulator which allows confronting the separating system containing at least one separating tool with the cutting points for cutting the cluster, with the suitable orientation and with the determined entering angle; j) securing the cluster in the second working area and separating each cast part from the cluster by means of the separating system in the second working area. a) defining a first spatial reference system (X, Y, Z) for a first computer vision system, defining a second spatial reference system (X',Y',Z') for a first industrial manipulator in a second working area where the cast parts are separated by means of a separating system, and interrelating both spatial reference systems according to the distances (x,and,z) separating them and the orientation of each axis; b) developing a basic programming algorithm for the first industrial manipulator based on movement instructions through parameters; c) storing data corresponding to the cast parts, feeder lines (15a, 15b, 15c) and risers (16a, 16b) of the clusters, comprising data of the cutting points for cutting the cast parts from the cluster; d) placing the cluster in a first working area; e) obtaining an image of the casting cluster by means of the first computer vision system; f) processing the image of the cluster obtained by the first computer vision system in phase e) to obtain the orientation of the cast parts and the coordinates of the cutting points according to the data of the image of phase e) and the data stored in c); g) converting the coordinates of the cutting points and orientation of the parts of the first spatial reference system (X, Y, Z) of the first computer vision system to the second spatial reference system (X', Y', Z') of the first industrial manipulator; h) determining the entering angle for separating each cast part based on reference entering angle values contained in a database in computer equipment; i) transmitting the coordinates and orientations calculated and the entering angle of phase h) to the first industrial manipulator which allows confronting the separating system containing at least one separating tool with the cutting points for cutting the cluster, with the suitable orientation and with the determined entering angle; j) securing the cluster in the second working area and separating each cast part from the cluster by means of the separating system in the second working area.
