Research on the adaptive adjustment of the parameters in grinding process

Abstract

The grinding process is influenced by many factors which make it prone to fluctuations in the quality and hard to guarantee the effectiveness and reliability. Therefore, as for this problem, an adaptive adjustment model of the parameters in grinding process is established. First single factor experiments were conducted to get the influence of the processing parameters on the quality qualitatively and the variation range of the parameters can also be obtained. Then, based on the orthogonal experiments, multiple linear regression method was used to establish the empirical relationship between the processing parameters and product quality quantificationally. Moreover, the parameter sensitivity function was presented through the relationship. On the basis of the analyses above, the model of the adaptive adjustment of the parameters was presented using fuzzy theory and the adjustive sequence, direction and step length were given. Finally experiments were conducted and the results show the effectiveness of the adjustment method.
