摘要
铝基复合材料作为应用最广泛的一种金属基复合材料,具有高比强度、高比刚度、高导热性、高耐磨性、高耐腐蚀性等多方面优点。在加工该材料的薄壁零件时,飞行式电解铣削的方式不会产生加工应力,可以有效规避加工中的变形与震颤。通过分析研究加工电压及进给速度对加工效率产生的影响,总结得出试验结果:沟槽深度随加工电压及进给速度的增大而增大,且近似呈线性关系;进给速度的增大能够提升材料去除率,但上升的趋势由18.5%降至2.8%。在40 V加工电压的参数下,单次进给的最大沟槽深度为1.22 mm,最大材料去除率为608 mm^(3)/min。
As one of the most widely used metal matrix composites,aluminum matrix composites have the advantages of high specific strength,high specific stiffness,high thermal conductivity,high wear resistance,high corrosion resistance and so on.When processing thin-walled parts of the material,the flight-type electrochemical milling method does not generate processing stress,which can effectively avoid deformation and tremor in processing.This paper analizes and studies the influence of processing voltage and feed rate over processing efficiency.The test results indicate that the groove depth increases with the increase of processing voltage and feed rate and is approximately linear.The increase of feed rate can improve the material removal rate,but the upward trend is reduced from 18.5%to 2.8%.Under the parameters of 40 V processing voltage,the maximum groove depth of a single feed is 1.22 mm,and the maximum material removal rate is 608 mm^(3)/min.
