精益六西格玛在副箱气缸改进中的应用

Application of lean six sigma for Range Cylinder Improvement

介绍变速器副箱气缸使用时漏气故障,通过对气缸加工、装配、设计,运用六西格玛方法进行调查分析,确定失效原因,制定改进方案,并将改进方案应用在实际生产中,跟踪售后数据,改进效果显著,故根据车型设计匹配、加工控制是降低气缸漏气故障的关键。

Introduce the air leakage failure model on range cylinder during working condition, using six sigma method to investigate and analyze the cylinder machining, assembly, design, identified the root cause, established improvement measures, and implemented the measures in actual production, follow up the customer warranty claim data, improvement is efficiency, therefore, the vehicles matching design, process control for cylinder machining is the key to reduce the range cylinder air leakage failure rate.
