PPAP(生产件批准程序)
PRODUCTION PART APPROVAL PROCESS
一，定义（什么是PPAP）：definition
顾客对供应商的产品、生产条件、生产过程等方面的书面约定与认可。
PPAP is a production part approval process ud by US auto industry (GM, Ford, and Chrysler).
The Production Part Approval Process (PPAP) outlines the methods ud for approval of production and rvice commodities, including bulk materials, up to and including part submission warrant in the Advanced Quality Planning process. The purpo of the PPAP process is to ensure that suppliers of components comply with the design specification and can show documentary evidence that the level can be maintained during the life of the product.
二，目的（aim）：
确定供方是否已经正确微信登不了怎么办
理解了顾客工程设计记录和规范的所有要求，并且在执行所要求的生产节拍下的实际生产过程中，具有持续满足这些要求的潜在能力。
The Purpo of PPAP is to d历史选修一
etermine if all customer engineering design records and specification requirements are properly understood by the supplier and that the process has the potential to produce product meeting the requirements during an actual production run at the quoted rate.
三，过程要求：process requir
用于PPAP的产品必须：
1.取自重要的生产过程；
2.是1小时到8小时的生产，且规定的生产数量至少为300件连续生产的部件，除非顾客代表另有规定；
3.在生产现场使用与生产环境相同的工装、量具、工艺、材料和操作人员进行生产。
四，要求：qualification requirements
1.设计记录（design records）
－应提交包括成套零件图样在内的所有设计记录，如CAD/CAM、数据资料、零件图样和技术规范；
－所有图纸必须被批准，并是最新状态的；
－设计记录应包括YF产品工程师批准的任何工程更改文件（如果有）
Design records are engineering requirements for judging the acceptability of a part characteristic. For qualification, every feature of the product as identified by engineering specifications or part drawing/print must be measured. Design records are consider as, all customer and supplier design records (e.g.: C批复的格式
AD, Pro-E files, part drawing/ prints, specifications)
2.工程更改文件（如果有）Engineering Change Documents (if any)
Engineering Change Documents are defined as any authorized engineering change(s) (authorized by Motorola development engineering) not yet recorded in t雨水节
he design record but incorporated in the product, part or tooling.
3.顾客工程批准（如果要求）Customer Engineering Approval (If required)
Customer Engineering approval is the process that provides for two way communication between the component supplier & the responsible Motorola design engineering activity and through which the supplier requests concurrence for certain design and process changes.
Once Motorola design engineering determines that the change is feasible and an engineering approval is required, the supplier will complete and submit the Process Change Notification for approval.
4.设计FMEA Design FMEA
－只对有设计职责的供应商适用；
－采用FMEA工具和标准表格；
－保留在供应商处，任何时候可供客户评审。
FMEA is an Engineering “Reliability Tool” that helps to define,identify, prioritize, and Eliminate known and/or potential failures of the system, design, or manufacturing process before they reach the customer. The Goal of Design or Process FMEA is to eliminate the Failure modes or reduce their risk.
5.过程流程图 Process Flow Diagram
过程流程图建议采用提供的标准格式
－操作描述应尽量具体；
－过程流程图应体现全过程，包括所有接收、存储、螺旋藻片的功效
生产、检验、返工、包装和标签作业以及发运；
－过程流程图应与PFMEA和控制计划相适应；
－对于关键产品特性（KPC）和关键控制特性（KCC）应注明。
Process is a combination of people, equipment, method,Material, and enviro情感语句
nment that produces output, for a given product or rvice. Process Flow Diagram depicts the flow of materials through the process, including any re-work,repair operations or cycle time.
6.过程FMEA Process FMEA
－采用FMEA工具和标准表格；
－所有潜在失效模式和后果都应被考虑并设法消除；
－如果没有任何建议措施，必须在建议措施栏注明“无”；
－不要用“操作工失误”作为潜在失效，应从工艺和系统中寻找失效的根本原因；
－过程FMEA应由一小组共同完成，这个小组由每一与过程相关的部门代表组成；
－过程FMEA必须确定所有特殊特性（如主要、关键、重要特性）；
－要求评审所有客户和内部问题，并调整风险顺序数；
－过程FMEA是动态文件应在整个产品生命期中不断利用并更新，并提交最新版本。

7.尺寸结果 Dimensional Results
－该记录用于验证零件及总成满足所有图纸上和控制计划的尺寸要求；
－如果是多个型腔、铸模、冲模、仿形模或生产线生产的零件，供应商必须完成每个独立加工过程/变化的至少3个零件的尺寸评价；各个型腔、铸模、生产线必须在PSW和尺寸检验报告上标识；
－测量示意图（图纸）和控制计划上注明的所有尺寸、特性和规范应以适宜的格式与实测值一起列出；
－尺寸检查标识和报告应包括总成和零件；
－必须确定一件为标准样件。
Dimensional results are the measurements results taken off the five production parts from production tool, mold, or t-up. All dimensions (except reference dimensions),Characteristics, specifications as noted on the print and print notes should be measured and listed in a convenient format.
