本文研究了碳化硅晶须增强陶瓷刀具在inconel718高速铣削过程中的工件完整性、切屑形成和切削性能。使用圆形刀片进行切削试验，切削速度为300至2000 M/MIN，进给量为0.2 MM/齿，切削深度为1.5 MM，浸入比为0.25至1。使用三轴旋转测功机测量切削力。检查了刀具磨损和表面光洁度。对收集到的芯片进行显微图像分析。

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.
