METHOD FOR PRODUCING A TURBINE ENGINE PART, AND RESULTING MOULD AND INTERMEDIATE BLANK |
| 摘要 |
The invention relates to a method for producing multiple metal turbine engine parts, comprising steps consisting in:
a) casting a metal alloy in a mould in order to produce a blank (3); andb) machining the blank in order to produce the parts,
characterized in that the blank obtained by casting is a solid polyhedron having first and second sides (30a, 30b) and third and fourth sides (30c, 30d), in which the third and fourth sides extend between the first and second sides, flaring apart from the first side towards the second side, first at a first angle and subsequently at a second larger angle, and said at least one part is machined in the blank. |

1. A method for producing at least one metal turbine engine part, comprising steps consisting of:
a) casting a metal alloy in a mould in order to produce a blank; and b) machining the blank in order to produce the at least one part, wherein the blank obtained by casting is a solid polyhedron having first and second sides in which third and fourth sides extend between the first and second sides, flaring apart from the first side towards the second side, first at a first angle and subsequently, from a break of slope, at a second larger angle, and said at least one part is machined in the blank. |
