FINISH AND CUTTING SPEED ON CRITICAL PARTS OF JET ENGINES EDM MACHINED

THERE IS A PROBLEM IN ELECTRICAL DISCHARGE MACHINING (EDM) OF CRITICAL JET ENGINE PARTS DUE TO THE METALURGICAL DAMAGE TO THE SURFACE FINISH OF THE AREAS CUT BY EDM. EXTREME CARE MUST BE TAKEN, AND EDM CUTTING SPEED REDUCED NOT TO DAMAGE CRITICAL PARTS. EDM OPERATOR SKILLS AND ATTENTION HAVE SIGNIFICANT RELATIONSHIP TO QUALITY OF EDM WORK ON EXPENSIVE COMPONENTS. WE HAVE INVENTED A COMPUTER CONTROLLED EDM POWER SUPPLY WITH SUPER HIGH SPEED COMPONENTS, ADAPTIVE CONTROLS, DATA BASE, REMOTE VIEWING AND CONTROL THAT LENDS ITSELF TO RETROFITTING TO OLDER EDM MACHINE TOOLS IN JET ENGINE PLANTS SUCH AS GENERAL ELECTRIC, PRATT & WHITNEY, AVCO, ALLISON AND GARRETT. WE WISH TO DO A TRIAL RUN OF PARTS TO BE SELECTED BY WRIGHT-PATTERSON IN COOPERATION WITH AN ENGINE FIRM, OR WITH W-P, TO PROVE OUT OUR QUALITY ENHANCEMENT AS WELL AS COST REDUCTION, AND TO BUILD THE DATA BASE FOR FUTURE USEAGE. WE SEE SIGNIFICANT COST SAVINGS AND QUALITY IMPROVEMENTS FROM THESE TESTS THAT WILL MAKE PHASE II WORTHWHILE TO PURSUE. WE ARE INTERESTED IN SMALL COOLING HOLE DRILLING APPLICATIONS TOO.
