METHOD FOR MACHINING CAVITIES IN A TURBOMACHINE TURBINE DISC

摘要

A machining method for machining peripheral slots in a disk of a turbine of a turbine engine, such as an airplane turboprop or turbojet, the method including: machining the slots by reaming using a substantially cylindrical reamer of length greater than an axial thickness of the disk, and extending substantially parallel to the axis of the disk, outlines of the slots being machined by moving the reamer perpendicularly to its axis along the profile of each slot.
