Optimized tip performance for turbine airfoils is obtained through a sequenced manufacturing process. The turbine airfoils are assembled into the dovetail slots of a turbine disk. The tips of the turbine airfoils assembled in the turbine disk are then measured to determine the turbine airfoils that do not have adequate tip clearance. The tips of those turbine airfoils that do not have adequate tip clearance are then machined to obtain adequate tip clearance. Once all the turbine airfoils have adequate tip clearance, environmental coatings and/or thermal barrier coatings are applied to the blade tips.
