Which process is more economical, casting or forging or sheet metal fabrication, without considering initial and tooling costs?
It depends on the application, the shape of the item being made and the number being make.
Also to not include initial and tooling costs is unfair since an item that can be fabricated by welding has fewer tooling costs and is good for one time items.
casting is cheap but the quality which you expect may not be present

Casting is more economical but makes the metal weak. Forging makes the metal strong but costs more.

The basic consideration for manufacturing process decision of any component is
Application of the component,
Design of the component ,
Material to be used for the component ,
Quantity of the component
Finish and accuracy required by the component
Produceability
Economics is one amongst them , and that alone can not decide the manufacturing process.
