摘要
为提高磨削质量的预测准确性,引入信息熵的概念,提取砂轮转速、X轴进给速度和Y轴磨削深度等3个工艺参数,作为平面磨削工艺特征参数。通过对平面磨削工艺历史数据库中数据的训练,建立最大熵模型,设计了平面磨削工艺预测软件进行工艺参数预测,输出预测结果。对预测结果分析表明,基于最大熵原理的平面磨削工艺参数预测可为工艺专家系统提供最优工艺方案,提高平面磨削生产质量和效率。
To improve the accuracy of forecast on grinding quality, we introduce the concept of information entropy and extract grinding wheel speed, feeding speed in X axis and grinding depth in Y axis as the technological characteristic parameter. Through the training of plane grinding data in the database, we build the maximum entropy model and design a technological forecasting software of plane grinding to forecast the parameters and output the prediction results. The analysis of the prediction results shows that forecast of technological parameters in plane grinding by using principle of maximum entropy can provide the optimal technological plan for technology expert system and improve the quality and efficiency of plane grinding.
