摘要
压梗工艺为制梗丝生产线切梗前的预处理工艺,为加强对压梗工序的质量控制,建立了压梗工序质量控制评价方法,用于对压梗工序质量控制能力的判定。通过建立压梗厚度检测方法及评价方法,计算出压梗厚度的均值、标准方差S2、样本标准偏差S,过程控制能力指数Cp、Cpk,找到压梗工序的不足之处并加以改进,最终实现稳定压梗工序的质量控制水平。应用结果表明,该方法适用于对压梗机过程质量控制能力的评价,从而保证压梗工序质量控制的稳定性。
The process of stem flatten is the pre-process of stem cutting.To enhance the quality control of the stemflatten process,an evaluation method is developed to measure its ability.Based on the measurement and evaluation ofthe width of stem flatten,the average of width,variance S2 and standard deviation of samples,as well as index of pro-cess control Cp and Cpk are calculated.Thus the deficiency of stem flatten process would be figured out and then im-proved,and finally the level of quality control of stem flatten process would be remained stable.The application prac-tices have demonstrated that this method is suitable for evaluating the ability of quality control of stem flatten processand guarantees the stability of such a process.
