摘　　要：通过研究硬质合金和CBN刀具切削加工铌基合金材料过程中的加工性能,优化出适合铌基合金材料零部件超精密切削加工的刀具材料。通过硬质合金刀具在铌基合金材料切削加工过程中切削三要素(切削速度、进给量和切削深度)的正交切削加工试验,研究了其对切削加工表面粗糙度的影响,建立了硬质合金刀具切削加工铌基合金材料表面粗糙度预测模型,并利用AdvantEdge金属切削有限元仿真软件开展了切削工艺参数对切削加工过程的影响。The application of carbide and CBN tools on the cutting of niobium-based alloy is discussed and the appropriate tool material is obtained.The influence of cutting speed,feed rate and back engagement are discussed to analyze the performance of cutting parameters.The prediction model of surface roughness is built to evaluate the appropriate cutting parameters during the manufacturing of niobium-based alloy parts.Professional finite element software(AdvantEdge)is simulated on the influence of cutting parameters on the cutting of niobium-based alloy.
