摘　　要：为研究金属玻璃的微铣削表面粗糙度,采用直径为0.5 mm的双刃硬质合金微铣刀,在Vit1块体金属玻璃表面加工微尺度沟槽结构;以试件表面粗糙度Ra值为衡量指标,利用三因素五水平正交试验方法分析主轴转速、进给速度和铣削深度对微铣削表面质量的影响。试验结果表明:主轴转速对表面质量影响最为显著,而进给速度影响较小。对影响表面质量及形貌的原因进行了深入分析,其结果对研究Vit1块体金属玻璃的微铣削加工机理具有一定的借鉴意义。To study the influencing factors of micro-milling surface roughness of metallic glasses,two-edged alloy micro-milling tool with 0.5 mm diameter was used to process a micro-scale groove structure on the surface of Vit1 block metal glass.Setting the surface roughness Ra of the test piece as the measurement standard,three-factor and five-level orthogonal experiment method was used to analyze the effects of spindle speed,feed rate and axial of cut on the quality of micro-milling surface.The results show that the spindle speed has the most significant effect on the surface quality,while the feed rate has little effect.Moreover,the reasons that affect the surface quality and morphology were further analyzed.And the results may provide some reference for the micro-milling mechanism of Vit1 bulk metallic glass.
