摘　　要：针对尺度较大的微沟槽阵列结构加工成本高、效率低的问题,提出数控对磨修整的方法,在三轴加工中心上利用金刚石油石将锯片铣刀刃口区域修整出V形微刃,并使用修整后的锯片铣刀对铝合金材料进行角度120°、深度160μm的微沟槽阵列铣削试验。试验结果表明:修整后的锯片铣刀V形微刃两侧刃口规则整齐,锯片铣刀铣削后的微沟槽角度误差平均值为1.2°,沟槽深度误差为1.5μm,说明对锯片铣刀修整后进行V形微沟槽铣削的加工方法可行。To solve the problems of high processing cost and low efficiency of micro-groove array structure with large scale,the method of CNC grinding and trimming is proposed,and the cutting edge area of the saw-tooth milling cutter is trimmed into a V-shaped micro-edge by diamond petroleum stone on the three-axis machining center.The micro-groove array milling experiment with an angle of 120°and a depth of 160μm is carried out on the aluminum alloy material by using the trimmed saw-tooth milling cutter.The results show that the edges on both sides of the V-shaped micro-edge of the trimmed saw-tooth milling cutter are regular and neat,the average angle error of the micro-groove after milling is 1.2°,and the micro-groove depth error is 1.5μm.It shows that the processing method of V-shaped micro-grooves is feasible for the saw-tooth milling cutter by trimming first and then milling.
