摘　　要：以典型难加工材料硬质合金为研究对象,以微细激光铣削加工表面粗糙度为质量指标,设计了正交实验方案,获得了硬质合金在Q频率、激光电流、Q释放时间、激光扫描速度、激光扫描次数五因素四水平下的表面粗糙度,用方差和极差分析比较了各工艺参数对表面粗糙度的影响趋势,得到了最优的工艺参数组合。The orthogonal experiment was designed as studying on the typical alloys which are machined hardly and taking surface roughness in micro laser milling for quality index.The surface roughness of cemented carbide was obtained under five factors and four levels including Q frequency,laser current,Q release time,laser scanning speed,laser scanning times.The influence of process parameters on the surface roughness was compared with the variance and dissimilarity analysis,and the optimal process parameters were obtained.
