Zusammenfassung:	The present invention relates to a method for the construction of rotor and stator elements of turbomachines, comprising: readying an ingot (1) of material to be machined; performing cuts in the ingot (1) so as to delimit blocks (10) of material interposed between portions of material intended to form blades (2) of the rotor or stator element; removing said blocks (10) freeing passages (11) between the portions of material; finishing the portions of material until the final shape is given to said blades (2) and to the passages (11). Execution of the cuts comprises: making first slots (6) on a first side (3) of the ingot (1), wherein the first slots (6) penetrate only partially through a thickness (t) of the ingot (1) to delimit into said ingot (1) a first half-block (7) of material joined to the ingot (1); making second slots (8) on a second side (4) of the ingot (1) opposite to the first side (3) to delimit a second half-block (9) into the ingot (1). The first slots (6) and the second slots (8) intersect each other so that the first and the second half-block (7, 9) define a single block (10) removable from the first side (3) and/or from the second side (4). La présente invention concerne un procédé de construction d'éléments de rotor et de stator pour des turbomachines, comprenant : la préparation d'un lingot (1) de matériau à usiner ; la réalisation de découpes dans le lingot (1) de manière à délimiter des blocs (10) de matériau interposé entre des portions de matériau destinées à former des aubes (2) de l'élément de rotor ou de stator ; l'enlèvement desdits blocs (10) afin de dégager des passages (11) entre les portions de matériau ; la finition des portions de matériau jusqu'à donner la forme finale audites aubes (2) et aux passages (11). L'exécution des découpes comprend : la réalisation de premières fentes (6) sur un premier côté (3) du lingot (1), les premières fentes (6) pénétrant uniquement partiellement à travers une épaisseur (t) du lingot (1) pour délimiter dans ledit lingot (1) un premier demi-bloc (7) de matériau relié au lingot (1) ; la réalisation de secondes fentes (8) sur un second côté (4) du lingot (1) opposé au premier côté (3) pour délimiter un second demi-bloc (9) dans le lingot (1). Les premières fentes (6) et les secondes fentes (8) se croisent de sorte que les premier et second demi-blocs (7, 9) définissent un seul bloc (10) pouvant être retiré du premier côté (3) et/ou du second côté (4).
