    摘要:

    机床床身的质量对整机可靠性影响极大，对其进行合理的评价可以指导工艺规程的改进。针对热时效过程下机床床身的质量进行定量评价，提出热时效熵的概念。从5M1E 6个方面分析导致床身质量损失的原因，采用模糊综合评价等方法获得对6个方面的初始评价值，然后结合熵权法和基于Vague集的模糊评判得到各影响因素的综合权重，最后基于6个因素的综合权重与初始评价值得到床身质量综合评价值。

    Abstract:

    The quality of lathe bed has a great influence on the reliability of the complete machine, and reasonable evaluation can guide the improvement of process regulation. On the basis of quantitative evaluation of the bed's quality in thermal aging process, the concept of thermal aging entropy is proposed. The cause of lathe bed quality problem are analyzed in six aspects of 5M1E. By fuzzy comprehensive evaluation, the preliminary evaluation of the six aspects is obtained, and then the entropy assessment is combined with the Vague fuzzy evaluation to attain the comprehensive weights based on the six factors. Finally the integrated weighting factors and the preliminary evaluation are used for comprehensive evaluation of lathe bed quality.
