OPTIMIZED PROCESS FOR MANUFACTURING A MONOBLOC WATER DISC WITH ABRASIVE WATER JET

摘要

The present invention relates to a method for manufacturing a monobloc blisk comprising a step of cutting by abrasive water jet a block of material (100) in the general shape of a disc, made to remove material of the block at inter-vane spaces to reveal blade preforms extending radially from a hub, the step of cutting by abrasive water jet comprising, for the realization of each space inter blades: - a first three-axis cut of a piece (114a) passing through the thickness of the block (100), implemented so that the cut piece escapes from the block (100) automatically by gravity; followed by at least one refining cut.
