Fillet machining without adaptive probing and parts finished thereby

A forged part having airfoil and platform surfaces finished by a method comprising:

• generating one or more surfaces on a model of the part using a computer system, wherein the one or more surfaces represent an approximate region to be machined on the part and an offset surface corresponding to a selected machining tool;
• extending the offset surface generally linearly in at least one direction to create a drive surface for use by a computer numerical control program;
• creating a machining tool path drive geometry;
• using the machine tool path drive geometry and the drive surface to create a computer numerical control path for a machining tool, wherein the computer numerical control path extends in at least one direction beyond the approximate region to be machined;
• and
• running tool paths on the part in a fixture.

A system for finishing a part having excess material, said system comprising:

• a machining tool;
• and
• a computer system programmed to:
• generate one or more surfaces on a model of the part, wherein said one or more surfaces represent an approximate region to be machined on the part and an offset surface corresponding to said machining tool;
• extend said offset surface generally linearly in at least one direction to create a drive surface for use by a computer numerical control program;
• create a path drive geometry for said machining tool;
• create a computer numerical control path for said machining tool based upon said path drive geometry and said drive surface, said computer numerical control path extends in at least one direction beyond said approximate region to be machined;
• and
• run tool paths on the part in a fixture.
