Claim Text:
1. A method for machining a component, comprising: establishing desired component shape and dimensions for a work piece machined surface to be formed by an electrical discharge machining (EDM) or a laser machining ablation method, which creates a recast oxide layer on the machined surface; establishing ablation machining speed and energy application rates for forming the machined surface to the desired component shape and dimensions; determining recast oxide layer thickness that will result from performing the ablation machining speed and energy application rates, prior to said machining; determining a fluoride ion cleaning (FIC) process that is intended to remove all of the previously determined oxide layer thickness, prior to said cleaning; ablation machining the work piece with an EDM or laser machining apparatus, at the established machining speed and energy application rates, so that a resultant machined surface of the work piece conforms with the established component shape and dimensions, forming a recast oxide layer of the previously determined thickness there upon; performing the determined FIC process with FIC apparatus; inspecting the work piece after completion of the FIC process, in order to confirm that the machined surface of the work piece conforms with the established component shape and dimensions and that it has a clean surface, which has no recast layer.
