摘要
以两类错误损失费用最小为目标,对现行发动机零组件加工质量控制中以x±3σ作为控制图控制界限的方法进行了改进,建立了确定最佳控制界限(Kσ)的数学模型与最优控制界限(K)的算式。通过实例对优化结果和现行“x±3σ”方法的结果进行了比较和分析,进一步说明了该方法的优越性。
Aimed at the least loss costs of the two types of errors, the method which takes “x ± 3σ” as the control limits of control-charts in engine subassemblies machining quality control was improved. The mathematics model which confirms the optical control limits was built and the formula for calculating the optical control parameter was obtained. The advantages of method are proved by the comparison and analysis with the results with x ± 3σ method.
