LASER/EDM DRILLING MANUFACTURING CELL Abstract A process and apparatus for drilling precision small diameter holes in fuel nozzle parts includes the process of directing a laser beam against the nozzle part at a first hole drilling station to form an undersized hole therethrough and thereafter positioning the nozzle part with the laser hole formed therethrough in alignment with a wire electrode of an electrical discharge machine and controlling the energy input to the electrode wire and advancing it with respect to the preformed laser hole so as to form a precision hole diameter and surface finish throughout the length of the laser beam formed hole as EDM particles are flushed through a flow path defined by the laser hole from one face to the opposite face of a part wall.
