【摘要】 在概述一般的工序能力指数计算方法的基础上,提出应用成组技术把工艺过程相似、结构相同而公差要求不同的零件归类,通过数据变换转化为服从同一分布的数据,由此计算工序能力指数,旨在解决多品种小批量生产方式下计算工序能力指数中数据不足和工序能力指数繁杂的问题。更多还原

【Abstract】 This paper summarizes methods of calculation of process capability indexes.In multi-specification and small-batch production,there are many process capabilities if every product is calculated.Group Technology(GT)is employed to classify products with similar processes,the same structure and different tolerance requirements,then to teanstorm the products into data subject to the same distribution.更多还原
