Abstract (en)

[origin: WO2004096493A1] The invention relates to a method for rounding part edges, in particular for turbomashines. According to said invention, an edge (2,3) formed by at least two adjacent surfaces (4, 5) of a part (1) is rounded in a direction to said adjacent surfaces. A jet (7) consisting essentially of abrasive particles is directed to the edge (2, 3), the jet centre being tangential with respect to a bisectrix (6) between said surfaces (4, 5). Said jet is displaceable according to a defined feed with respect to the part (1) along the edge (2,3) in such a way that a defined removal of the part material is carried out associated with rounding in the direction of the surfaces (4, 5).
