| 摘 要： | 为了实现微通道的高效加工,提出利用微细铣刀对铝合金薄板进行微通道阵列结构加工,并通过改变加工工艺参数的方法,系统研究了铣削加工参数(背吃刀量、进给速度和主轴转速)对微通道的几何尺寸的影响规律。研究结果表明:选用直径为0.4mm铣刀的条件下,加工出微通道的宽度随着背吃刀量和进给速度的增大而逐渐增大,且背吃刀量的影响较为明显。在6 000~21 000r/min的主轴转速范围内,随着主轴转速的增加,微通道的宽度尺寸变化不大。因此,通过选择优化的切削加工工艺参数,可以实现微通道阵列结构的加工。

| Abstract: | In order to improve the milling efficiency of microchannels, the micro milling cutter is proposed to fabricate the microchannel array structures on the aluminum alloy sheet. The processing parameters such as back engagement, feed speed and spindle speed are varied to study their influence on the geometry size of microchannels. The result shows that when using the milling cutter with diameter of 0.4 mm, the width of microchannels increases with the increasing of back engagement and feed speed, especially for the back engagement. When the cutting speed is in the range of 6 000~21 000 r/min, the width size of microchannels barely changes with the increasing of spindle speed. So microchannel array structures can be fabricated through selecting optimized processing parameters. |
