基于价值流的胖轴精益生产分析

Optimization of Sulfidation Machine Chief Axle Process Applied on Value Stream

为提高胖轴作业效率,通过调查,首先应用价值流图技术,绘制当前状态图,分析胖轴加工过程中存在的生产计划、在制品库存、生产方式等问题,区分胖轴加工中的增值和非增值部分;然后,依据精益思想和工业工程的基本手法,提出平衡物流、合并工序、拉动生产等改善措施,绘制未来状态图作为改善的路标。实施后,胖轴批量加工时间比原来减少54%,形成均衡、拉动生产,减少了在制品库存,使生产过程大为精简。

In order to improve work efficient of Fat-bearing, the present status chart of fatbearing is drawn by applying on the value stream technique. After analyzing some problems in Fat-bearing processing, such as production schedule, work-in-process, production mode and so on, increase and decrease in value parts are distinguished. According to lean thinking and the basic method of IE, some improvement method is put forward, for example, logistics equilibrium, procedure combination and production management After improvement, the process time of Fat-bearing is reduced up to 54%, the balance and pull production are formed, and the inventory is cut down. The production process is simplified.
