摘要

为了研究加工参数对钛合金超声辅助磁性磨料光整加工（UAMAF）的影响，以表面粗糙度和材料去除率（MRR）为指标开展正交试验研究，运用信噪比与灰色关联度分析方法分别对加工参数进行单目标和多目标优化。结果表明，以表面粗糙度和 MRR 为目标的最佳工艺为磨粒粒度均为50/60#，振幅均为14μm，工具转速分别为1000r/min和1200r/min，磁极–工件间隙分别为1mm 和1.25mm，加工时间分别为40min和30min，优化的表面粗糙度R

和MRR分别为0.08μm和30.5mg/h ；综合考虑表面粗糙度和 MRR 的最佳工艺为磨粒粒度50/60#、振幅14μm、工具转速1200r/min、磁极–工件间隙1.00mm、加工时间30min，表面粗糙度R

和 MRR分别为0.12μm 和27.9mg/h。

Abstract

In order to study the influence of machining parameters on ultrasonic-assisted magnetic abrasive finishing (UAMAF) of titanium alloy

the orthogonal experiments were carried out with surface roughness and material removal rate (MRR) as evaluating indicator. The single-objective and multi-objective optimization of the machining parameters were carried out based on signal-to-noise ratio (S/N) and grey correlation analysis methods. The results show that the best process aiming at surface roughness and MRR is the abrasive particle size of 50/60#

amplitude of 14μm

and tool speed of 1000r/min and 1200r/min

magnetic pole and workpiece gap of 1mm and 1.25mm

finishing time of 40min and 30min respectively. The optimized surface roughness and MRR are R a 0.08μm and 30.5mg/h respectively. The optimum process combining surface roughness and MRR is the abrasive particle size of 50/60#

amplitude 14μm

finishing time of 30min

magnetic pole and workpiece gap of 1.00mm

tool speed of 1200r/min. The surface roughness and MRR are R a 0.12μm and 27.9mg/h respectively.
