THIS PAPER INVESTIGATES THE WORK PIECE INTEGRITY, CHIP FORMATION, AND CUTTING PERFORMANCE OF SiC WHISKER REINFORCED CERAMIC TOOLS DURING HIGH SPEED MILLING OF INCONEL 718. CUTTING TESTS WERE PERFORMED USING ROUND INSERTS, AT CUTTING SPEEDS FROM 300 TO 2000 M/MIN, FEEDS UP TO 0.2 MM/TOOTH, DEPTH OF CUT UP TO 1.5 MM, AND IMMERSION RATIO OF 0.25 TO 1. CUTTING FORCES WERE MEASURED USING A 3-AXIS ROTATING DYNAMOMETER. TOOL WEAR, AND SURFACE FINISH WERE EXAMINED. MICROGRAPHIC ANALYSIS WAS PERFORMED ON THE CHIPS COLLECTED.
