Abstract
A method of forming a curved slot in a turbine disk includes the steps of forming a pre-slot in the turbine disk and finishing the pre-slot to form a slot that receives a portion of a turbine blade. The turbine disk including a first face, an opposing second face, and an outer perimeter surface extending between the first face and the opposing second face. The pre-slot includes a first curved wall and a second curved wall that each extend between the first face and the opposing second face. An intersection between the outer perimeter surface and each of the first curved wall and the second curved wall is defined by a curved line.

A method of forming a slot in a turbine disk, the method comprising the steps of:
- forming a pre-slot in a turbine disk, the turbine disk including a first face, an opposing second face, and an outer perimeter surface extending between the first face and the opposing second face and the pre-slot including a first curved wall and a second curved wall that each extend between the first face and the opposing second face, wherein an intersection between the outer perimeter surface with each of the first curved wall and the second curved wall is defined by a curved line;
- and
- finishing the pre-slot to form a slot that receives a portion of a turbine blade
A method of forming a turbine disk, the method comprising the steps of:
- forming a pre-slot in a turbine disk, the turbine disk including a first face, an opposing second face, and an outer perimeter surface extending between the first face and the opposing second face and the pre-slot including a first curved wall and a second curved wall that each extend between the first face and the opposing second face, wherein an intersection between the outer perimeter surface and each of the first curved wall and the second curved wall is defined by a curved line;
- finishing the pre-slot to form a slot that receives a base of a turbine blade;
- and
- inserting the base of the turbine blade into the slot of the turbine disk, wherein a shape of the slot corresponds to a shape of the base of the turbine blade.
A turbine disk comprising:
- a body portion including a first face, an opposing second face, and an outer perimeter surface extending between the first face and the opposing second face;
- and
- a slot in the body portion that extends between the first face and the opposing second face, wherein the slot receives a portion of a turbine blade and defines an opening on the outer perimeter surface, and the opening is defined by two curved lines.
