摘要：An ultrasonic vibration assisted helical milling method is proposed for machining 40CrNiMoA/glassfiber reinforced plastics (GFRP) laminated composites. The tool trajectory of ultrasonic vibration assisted helical milling method is analyzed, and the ultrasonic vibration amplitude range of effective machining is deduced. The cutting force, cutting temperature and machining quality of three different machining method under the same tool cutting speed and machining efficiency are analyzed. The results show that, compared with the traditional helical milling and drilling, the cutting forces of ultrasonic vibration assisted helical milling of 40CrNiMoA are reduced by 25% and 40%, respectively; while the maximum cutting temperatures are decreased by 15.7% and 22%. When processing GFRP, the maximum temperature is reduced by 16.5% and 50%. Meanwhile, the hole walk surface quality is significantly improved, the manufacturing defects, such as tearing and burrs, are significantly reduced to reach the manufacturing requirements. © 2015, China Ordnance Society.
