FMEA-失效模式及后果分析.ppt

Assigning KPCs/PQCs 指定KPCs/PQCSSeverity vs. Likelihood 严重度与可能性 CRITICAL 关键的 MINOR 次要的 MAJOR 主要的 PQC STANDARD 标准的 KPC REDESIGN 重新设计 Zero 零 Small 小的 Significant 重要的 High 高的 Severity of an Adverse Consequence 不良后果的严重度 Likelihood of an Adverse Consequence 不良后果的可能性 Extra Additional Standard PQC Functional Checks, Verification/Traceability, Safety Compliance and Component Handling All Products and Processes Levels of Care KPC What is a KPC? 什么是KPC? A Key Product Characteristic (KPC):关键产品特性 Is a product characteristic where reasonably anticipated variation (Standard Care) is likely to significantly affect customer satisfaction with the product. 合理的预期变差(标准关注)可能严重影响顾客对该产品的满意度的产品特性. Designated when EXTRA CARE, in the form of VARIATION REDUCTION, is required about a target, because the process CANNOT meet the target consistently. 指定的产品特性.当过程不能总是满足该特性目标时,我们必须实行额外关注.以降低变差. Means mfg./assembly must strive for MUCH BETTER THAN +3s quality (Cpk1.0). 意味着在制造/装配过程中必须努力使CPK远大于1 Target目标 Anticipated State 预期的状态 Desired State 追求的状态 Target 目标 Desired State 追求的状态 Extra Additional Standard PQC Functional Checks, Verification/Traceability, Safety Compliance and Component Handling All Products and Processes Levels of Care KPC What is a PQC? 什么是PQC? A Product Quality Characteristic (PQC): 产品质量特性 Is one in which the customer is equally satisfied across the entire specification. 顾客可以接受的产品规范. Designated when STANDARD CARE is likely to exceed the spec, and EXTRA CARE by mfg./assembly is necessary to consistently CONTROL the process to be “on target”. 指定的特性.用标准关注不能达到产品规范要求,需要在制造/装配过程中采取特别关注,以控制过程总是达到目标. Means mfg./assembly must strive for BETTER THAN +3s quality (Cpk 1.0). 意味着制造/装配过程必须努力使CPK大于1 Target目标 Target目标 Anticipated State 预期的状态 Workshop现场研讨__30’目的：练习识别与失效原因,失效模式和失效后果相关的风险数 利用前面练习中分析的失效模式、原因、后果进行风险数评定. 当填写表格时: 利用前面的分析的结果（失效模式，原因及后果） 首先识别每一个失效后果的严重度数S; 再评定每一个失效原因发生的频度数O; 如果存在针对该失效模式的现行探测措施，则确定探测度D; 计算SO和RPN，并识别优先关注的高风险项目； 填入下页失效模式及后果分析表格中：
