Research on Improving Manufacture Reliability of Spindle Boxes Based on Manufacture Error Correlativity
Abstract:
Processing of following holes may decrease manufacture precision of processed spindle holes. To decrease the unfavorable influence on spindle holes and improve the manufacture reliability of spindle boxes, the paper applies a partial correlation relationship and hypothesis testing to find the holes which have correlation with the spindle hole. The partial least squares establishes the mathematical model of manufacture error correlativity so that the paper finds the magnitude of influence these holes has on the spindle hole through coefficients of the modeling. The model provides the foundation for improving manufacturing accuracy of holes that have great influence on spindle holes to decrease manufacturing error of the spindle hole and improve the reliability of spindle boxes. The example proves the methods applied to decrease the unfavorable influence on the spindle hole are specific and operable.
