Abstract
A method of manufacturing a turbine disk includes the steps of machining an initial slot using a cutting tool and machining intermediate and semi finished slot using a form tool that forms surfaces of the slot except for the bottom surface. A final finishing step utilizes a cutting tool that includes a shape that forms the bottom portion of the disk slot.

A method of manufacturing a turbine disk, comprising the steps of:
- forming a slot in an initial form in a turbine disk;
- removing material from the turbine disk from surfaces defining the slot to an intermediate finished form using a machine tool;
- machining side surfaces of the slot to a partial final form using a first cutting tool, wherein only the side surfaces of the slot are machined to the partial final form using the first cutting tool;
- and
- machining only a bottom surface of the slot to a completed final form using an end mill that is different than the first cutting tool.

A method of manufacturing a turbine disk, comprising the steps of:
- machining a slot to an initial form in a turbine disk using a first cutting tool, the cutting tool creating a rough slot;
- machining the slot to an intermediate form using a second cutting tool different from the first cutting tool, the second cutting tool creating a semi-finished slot;
- machining side surfaces of the slot to a final form using a third cutting tool different from the first cutting tool and the second cutting tool, wherein the third cutting tool machines only the side surfaces of the slot to a desired final form;
- and
- machining only a bottom surface of the slot to a final form using an end mill different than the first, second and third cutting tools.
