摘要
碳纤维复材是典型的难加工材料,碳纤维复材飞机蒙皮构件的高质高效切削铣边技术是国内外航空先进制造技术研究热点。探讨了碳纤维复材的超高压水切割机理,分析了大尺寸碳纤维复材飞机蒙皮构件精密水切割装备的设计难点,阐述了500 MPa压力级水射流机组、五轴联动水切割机床、浮动点阵柔性托架、水刀头机构、数控系统等部件的关键技术,经过方向舵蒙皮精密水切割试验表明符合相关加工要求。
Carbon fiber composite is a typical hard-to-machine material.High-quality and high-efficiency cutting and milling technology of carbon fiber composite aircraft skin components is a research focus of advanced aviation manufacturing technology at home and abroad.The mechanism of ultra-high pressure water cutting for carbon fiber composite was discussed,and the design difficulties of precision water cutting equipment for large-size carbon fiber composite aircraft skin components were analyzed.The key technologies of 500 MPa pressure level waterjet unit,five-axis linkage water cutting machine tool,floating lattice flexible bracket,water cutting head mechanism,numerical control system and other components were described.The precision water cutting test of rudder skin shows that it meets relevant machining requirements.
