摘要

摘要: 从估算工艺系统的输入性能即工艺要素能力出发,构造了一种具有工艺能力一般性质的工艺要素能力的通用量化函数,提出了一种度量整体工艺质量的指标——综合工艺能力指数及其估算函数,为在概要工艺设计阶段评估和优选工艺方案提供了有效手段.

Abstract: It is crucial to estimate the process capability of process alternatives selected in the macro-level conceptual process planning during early stage of product development. The classical process capability index is only suitable to estimate micro-level single quality characteristic possessing statisticalnormal distribution in batch production scenario. Based on the idea of estimating the inputs (process elements) performance rather than the outputs (quality characteristics) ones of manufacturing system, a generic function for measuring the capability of process element was put forward and then the estimation formula of composite process capability index was developed. This index was able to measure the whole quality level of a manufacturing system with multiple process elements and multiple quality characteristics. A case study concerned with conceptual process planning for a spacecraft frame part was used to illustrate the validity of the estimation formula of composite process capability. The proposed composite process capability index was used as a effective tool to approximately estimate and select the optimal process alternatives during conceptual process planning in the early stage of product development.
