Study of Si_3N_4 Ceramics Materials in Magnetic Abrasive Finishing Based on Orthogonal Orthogonal Test

利用雾化快凝法制备的球形磁性磨料,设计合理的交互正交优化实验,对Si_3N_4陶瓷材料进行磁力研磨加工,探究加工Si_3N_4材料的最佳工艺参数组合。并对各影响因素进行分析。通过SEM扫面电镜及白光干涉仪对加工后的表面粗糙度进行分析,探究所能达到的最佳表面粗糙度。结论:当工艺参数为:转速S=1000 r/min,加工间隙δ=2.5 mm,磨料填充量为2.5 g时,经分析可得,工件的平均表面粗糙度由加工前的1.95μm下降到0.56μm。

Design a reasonable orthogonal orthogonal optimization experiment to polish Si3N4 ceramics with The spherical magnetic abrasive prepared by atomization fast coagulation.The magnetic abrasive processing of Si3N4 ceramic materials was carried out to explore the optimum combination of process parameters for processing Si3N4 materials.And the influence factors are analyzed.With the aid of white light interferometer and scanning electron microscope,the surface morphology of the polishing was analyzed.The results showed that the average surface roughness of the workpiece decreased from 1.95 μm to 0.56 μm when the process parameters were speed S =1 000 r/min,the machining gap δ=2.5 mm and the abrasive filling amount of 2.5 g.
