Zusammenfassung:	The present invention relates to a method for the construction of rotor and stator elements for turbomachinery comprising: preparing a solid (14) of material to be machined; performing cuts (15', 15", 15'", 15"", 22', 22", 22'", 22"") in the solid (14) so as to delimit blocks (20, 24, 28, 29, 32) of material interposed between portions of material intended to form vanes (9) of the rotor or stator element (1 ); removing said blocks (20, 24, 28, 29) to clear passages (27) between the portions of material; finishing the portions of material to provide the final shape to the vanes (9) and to the passages (27). For the formation of each of the passages (27), interrupted cuts (15', 15", 15'", 15"", 22', 22", 22'", 22"", 35) are performed in the solid (14) to delimit in the solid (14) at least one block (20, 32) and, after the removal of said at least one block (20, 32), a respective blind cavity (21, 33). The interrupted cuts (15', 15", 15'", 15""22', 22", 22'", 22"", 35) are substantially rectilinear cuts that terminate inside the solid (14) and, were they to continue beyond respective terminal points (20), they would intersect the final geometric shapes of the rotor or stator element.
