通过介绍挤出过程SPC系统的设计原则和逻辑关系,给出挤出过程SPC系统软件的设计思路及设计过程。对挤出过程SPC系统软件进行实际运行实验,在相同压力值下,通过设定不同上下偏差,对应用统计过程控制所得到的结果进行对比分析,以此说明在挤出过程控制系统软件的功能及应用。
By introducing the design principles and logical relations of SPC system during extrusion process, the design ideas and design process of SPC system software during extrusion process are given. The SPC system software in the extrusion process actual running experiments at the same pressure value, by setting different upper and lower deviation, the application of statistical process control results obtained comparative analysis to illustrate the function of the extrusion process control system software And application.
