基于6σ的抛光工序质量改善

Quality Improvement of Polishing Process Based on 6σ

针对汽车生产线零部件区域抛光工序遇到的瓶颈问题,采用6σ分析方法,从问题定义、问题测量、问题分析、问题改进及成果保持五个方面入手,确认根本原因并提出改进措施,使链板抛光后倒角合格率大于99.5%,每年节约相关生产成本73万元。

Aiming at the bottleneck encountered in the polishing process of automobile parts in production line, 6σ analytical procedure was used to identify the primary cause with improving measures from the aspects of problem definition, problem measurement, problem analysis, problem improvement and results maintaining. So that the pass rate of polishing process of rear chamfer of chain plate is more than 99.5% with an annual saving of 730 000 Yuan for relevant production cost.
