摘要：The present invention relates to a method for producing a one-piece bladeddisc, comprising: a step in which an abrasive water jet is used to cut a block of material insuch a way as to leave behind blade preforms extending radially from a disc (4), whilekeeping material forming bridging means (112) between at least two directly consecutiveblade preforms; then a step in which the blade preforms are milled in such a way as toproduce semi-finished blades (202) in profile; then a step in which said bridging means(112) are removed; and then a step in which the semi-finished blades (202) are finish-milled in such a way as to obtain the blades (2) to the final profile.
