液氮内喷式钻头φ4-切削性能对比试验

检测所研制液氮内喷式冷却钻头的切削性能，依据《麻花钻寿命试验方法》（JB/T 11453-2013）规定的检测方法，对碳纤维复合材料进行孔加工，检测加工后孔形貌和刀具磨损形貌。To evaluate the cutting performance of the developed internally nitrogen-jet cooled drill bit, hole machining was conducted on carbon fiber reinforced polymer (CFRP) composites in accordance with the test methods stipulated in *Standard for Life Test of Twist Drills* (JB/T 11453-2013). The morphology of the machined holes and the tool wear morphology were then inspected.
