What is a Process FMEA? 什么是程序FEMA?
A systemized group of activities intended to:
一个系统化团队:
Recognize and evaluate the potential failure of a process and its effects
确定和评价过程的潜在失效和后果
Identify actions that could eliminate or reduce the chance of the potential failure occurring
确定可以消除或减少潜在失效发生机会的措施
Document the process - it defines what a process must do to satisfy a customer
把以上的措施规定下来并标准化--操作JIS

Purpose of PFMEA’s
PFMEA‘s 的目的
To identify potential failure modes and rate the severity of their effects
确定有哪些潜在失效模式和其后果严重性
To identify Critical Characteristics
确定评价特性
To rank order potential process deficiencies
确定潜在过程缺陷的等级
To focus on eliminating process concerns and help prevent problems from occurring
注意消除装配过程的缺陷和防止问题发生

Customers of FMEA’s FMEA‘s 的顾客
The customer for a Process FMEA is normally seen as the “End User”.
“最终用户”,也指车辆的最终用户。
However, customers can also be any subsequent or downstream manufacturing or assembly operation, as well as a service operation.
,以及服务工作。

PFMEA 什么时候完成
The PFMEA is a living document and must be updated whenever significant changes in the manufacturing or assembly process occur
PFMEA当:
零件设计基本完成;
基本操作已经了解;
相关操作流程已经明确;
--就可以制定PFMEA,原则上越早越好。
PFMEA同时还是一个动态的文件,在制造和装配过程中发生任何显著变化时,文就可件必须更新。
