摘要: 在精密磨削加工过程中,为了使砂轮保持锐利程度及正确的几何形状,需要对砂轮及时修整。如何有效预测金刚笔修整磨损一直是磨削加工中的一个技术难题。根据金刚笔修整磨损机理分析,提出了基于声发射信号的串行优化算法支持向量机(SMO-SVM)金刚笔修整磨损预测方法,利用小波包算法对声发射信号特征信息进行提取,建立了将小波包提取的声发射信号特征量作为的输入SMO-SVM的金刚笔磨损预测模型;实验结果表明基于声发射信号的SMO-SVM模型对金刚笔磨损前后的预测准确性达到95.257 1%以上。

Abstract: In precision grinding process, grinding wheel should be dressed in time to keep the wheel sharpness and correct geometry. Now, it is still a difficult problem how to effectively predict the dresser wear in process. According to the single-point dresser wear mechanism, a method was proposed to predict the single-point dresser wear based on the acoustic emission signal and the sequential minimal optimization support vector machines (SMO-SVM) model. The wavelet packet algorithm was used to exact acoustic emission signal characteristic information. According to the large sample of acoustic emission signal, the sequential minimal optimization support vector machines (SMO-SVM) model was established to predict single-point dresser wear, and the signal characteristic information is as input for SMO-SVM model. The experiment result shows that the model's accuracy is above 95.257 1%.

Key words: single-point dresser wear, SMO-SVM, intelligent prediction, experiment
