Experimental Study on Abrasive Flow Polishing of Common-rail Tube Micro-holes and Surface Roughness Prediction

  • 摘要: 针对共轨管微小孔电火花加工表面的光整加工问题,采用磨粒流抛光工艺,并通过正交实验探索了加工参数及其交互作用对孔道表面粗糙度的影响规律;基于二阶响应曲面模型和幂函数模型分别建立了表面粗糙度预测多元非线性回归模型。研究结果表明:加工参数对抛光效果的影响显著,而交互作用对其影响较小;抛光压强、磨料浓度及加工时间对孔道表面粗糙度的影响均为负效应,磨粒粒径大于148 μm时对表面粗糙度的影响为正效应,粒径小于该临界值时表现为对抛光效率的正效应影响;在最优参数组合条件下,孔道表面粗糙度值(Ra)由初始的1.31 μm降至0.20 μm;二阶多项式回归模型相对于幂函数回归模型有更高的预测精度,相关系数高达0.990,预测误差在9.54%以内。
