Predicting Polishing Performance of Magnetic Abrasive and Optimizing Its Preparation Process Parameters Based on Taguchi-GA Synergy
In this study,an orthogonal experiment was designed by changing the preparation process parameters of bonded magnetic abrasives.Then,a series of magnetic abrasives with different specifications were prepared,and their morphology and composition were detected.Taking the 3D-printed AlSi10Mg plate as the processing object,the influence of the magnetic abrasive preparation process parameters on the polishing quality was revealed through the planar magnetic abrasive finishing experiment.A regression model between parameters and responses was established based on regression analysis,and the genetic algorithm optimized parameters.The results show that under the condition that SiC is 18～25 µm,the mass ratio of Fe to SiC is 4.7,the mass ratio of resin to curing agent is 2,the curing temperature is 100 ℃,the material removal rate is 1.7 mg/min,and the surface roughness is reduced from the original 3.90 µm to 0.27 µm with a reduction of 93.1%.
