何谓PFMEA 何时作PFMEA 何人作PFMEA
PFMEA (中文版)
通过产品及制造过程的重新设 最好 计,加入poka – yoke方法
替代
用更可靠的过程代替目 运用机器人技术或自动化生产 较好 前的过程以降低失误 技术
简化 使作业更容易完成
合并生产步骤,实施工业工程 较好 改善
检测
在缺陷流入下工序前对 使用计算机软件,在操作失误 较好
其进行检测并剔除
时予以告警
减少 将失误影响降至最低 采用保险丝进行过载保护等
质量是全员参与才可成就的,这早已成为共误,但人人树立预防失 误、防止缺陷的观念,并参与缺陷预防才是最重要的。人人参与预 防了,零失误、零缺陷可有望实现。
4. 追求完美。
在质量、成本、交期、技术和服务几个方面持续追求,比如质量的 “零缺陷”,如果公司文化中认为零缺陷不可实现,无疑会纵容 “人无完人、犯一两次错误没啥大不了的” 等观点的盛行,其结 果可想而知。理念会直接影响人的行动,建立持续追求完善的文化 是防错效果的根本保证。
FMEA表格之应用
典型的失效模式可能是下列情況:
弯曲、毛刺、孔错位、开孔太浅/深、漏开孔、转运损 坏、断裂、变形、表面太粗糙/平滑、接地、开路、短 路、贴错标签等
11)潜在失效后果
指失效模式对顾客的影响 应依据顾客可能注意到的或经历的情况来描述失
效的后果。例如:噪音、工作不正常、不稳定、 外观不良、粗糙、工作减弱、无法钻孔、无法紧 固、无法安装、不连接、无法表面加工等

PFMEA范本案例
PFMEA范本案例PFMEA (Process Failure Mode Effects Analysis),即工艺失效模式与影响分析,是用于识别、评估和控制过程故障和问题的方法。
下面是一个PFMEA范本案例,包括问题描述、风险评估和控制措施。
案例:XX公司生产线工序XPFMEA分析1.过程描述:工序X是生产线上的一个关键工序,该工序涉及零件的装配和测试。
在该工序中,零件被装配在一起,并进行功能性和可靠性测试。
整个过程由机器和操作员共同完成。
2.问题描述:在工序X中,出现以下潜在问题和风险:1)零件装配错误;2)错误的测试参数设置;3)不稳定的测试设备;4)操作员疏忽导致错误装配或测试;5)潜在的零件缺陷。
3.风险评估:为了评估上述潜在问题和风险的重要性和严重性,我们使用了一套1-10的风险评估矩阵,其中1表示风险较低,10表示风险较高。
问题可能性重要性严重性风险等级零件装配错误87956错误的测试参数设置79856不稳定的测试设备58640操作员疏忽导致错误装配或测试66954潜在的零件缺陷310721注意:风险等级=可能性*重要性*严重性4.控制措施:基于上述评估结果,我们必须采取适当的控制措施来减少或消除潜在问题和风险。
问题控制措施零件装配错误1)提供装配指导书和流程图;2)定期进行员工培训,确保操作员技能;3)引入自动化装配设备,减少人为错误。
错误的测试参数设置1)设定可编程的测试参数,并进行封装;2)详细记录正确的测试参数;3)定期进行设备校准和维护。
不稳定的测试设备1)定期进行设备维护和保养;2)评估设备的可靠性,进行适当的维护。
操作员疏忽导致错误装配或测试1)强调操作员的责任和重要性;2)建立良好的质量管理文化;3)使用自动化检测设备进行装配和测试。
潜在的零件缺陷1)加强供应商质量管理;2)引入100%检验,筛选出潜在问题。
注意:控制措施要具体、可行,并由有效的检验和监控机制支持。
