卷烟计量型测量系统的分析

Analysis of Cigarette Measurement System

摘要: 为准确了解卷烟计量型测量系统现状,将工序自检、过程巡检、出厂检验3个环节相同质量指标测量单元视为一个测量系统,采用MSA新方法对质量、圆周、长度、吸阻、硬度5个测量系统进行了分析。结果表明:5个测量系统的研究公差比(%P/T)在10%~30%之间,说明测量系统能力满足对产品质量判定的要求;除硬度测量系统外,4个测量系统的研究变异比(%R&R)在10%~30%之间,说明测量系统能力满足对生产过程改进分析的要求。

Abstract: In order to know the status quo of cigarette measurement system,five systems for measuring cigarette weight,circumference,length,draw resistance and hardness separately in operator's self-inspection,regular process inspection and ex-factory inspection were analyzed with MSA(measurement system analysis) method.The results showed that the precision to tolerance ratio(%P/T) of the five measurement systems ranged from 10% to 30%,which indicated that the capacity of measurement systems satisfied the requirements for product quality assessment;the repeatability and reproducibility ratio(%R&R) of four measurement systems(excluding hardness measurement system) ranged from 10% to 30%,which indicated that the capacity of the measurement systems satisfied the requirements for analysis and improvement of production process.
