摘要
由于采用自动生产线工艺,每个工序须在节拍时间内一次完成。如果设备管理和人员操作不到位,在后续生产过程中很难补救,容易导致管片成品外观质量出现问题。针对该情况,采用QC小组活动方法,通过调查统计,找出了影响管片外观质量的2个主要问题。分析提炼出产生以上问题的3个要因,并有针对性地采取措施,成功将重庆地铁6号线管片外观质量的合格率提高到了98.06%。
Each process of the automatic metro segments production line processes must be completed within the specified time. If device management and workers improperly operate, it＇s hard to remedy the errors in the subsequent production process, which wilt result in quality problems of metro segments. For solving the problem, QC group members of a factory in Chongqing finds out two main problems that influence the appearance quality of the segment by investigation and statistics, and abstracts three reasons why caused the two problems. Thus, taking corresponding measures, the segment appearance qualified rate of Chongqing Metro line 6 is increased up to 98.06%.
