Abstract
Methods and systems for wire-electro discharge machining of components are described. The method comprises machining a first component by moving a wire-EDM electrode along a first set of cutting paths associated with a plurality of cutting passes, the cutting paths determined based on a desired profile shape of the component, obtaining a cutting parameter of the first component post-machining, determining a first modified cutting path for a second component based on the cutting parameter, and machining the second component by moving the wire-EDM electrode along a second set of cutting paths associated with the plurality of cutting passes, the second set of cutting paths comprising the first modified cutting path.
