Zusammenfassung:	In an exemplary embodiment, a method for manufacturing turbine wheel airfoils includes: defining an initial design with an initial respective line for a straight line cut for a respective surface of each airfoil; evaluating an initial score for the initial design based on mechanical, aerodynamic, manufacturing cost, and robustness criteria; performing, in an iterative manner, a sequence of changes to the initial design, by adjusting the initial respective line for the straight line cut for the respective surface of each airfoil to generate different iterative designs; evaluating respective scores for each of the different iterative designs; selecting a design from the initial design and the different iterative designs that generates an optimized score based on the mechanical, aerodynamic, manufacturing cost, and robustness criteria; and cutting along the straight line for the surface of each airfoil, based on the selected design, to form each airfoil.
