Why a PFD?
一个全面详细的PFD是制定加工工艺的起点 – 图形的方式表示加工过程 – PFMEA的必要基础 - “Roadmap路标” – 工艺文件的出发点 - PFMEA, PCP, Routing, 有助于提高设备的性能. – 过程中如何控制非一致性材料? – 如何实施检查，哪些是必须的？ – 零件如何重新引入过程中? 一个改进了的PFD有助于改进PFMEA – 整个过程一目了然。 » changeover, fab, inspect, rework, scrap, move, store, audit – 明确定义了重要的产品和过程特性 » 产品特性 = 输出 = 潜在失效模式 » 过程特性 = 输入 = 潜在原因
