样件，试生产，生产控制计划，它们三者之间应该有哪些方面的区别？

各位好，今天在作体系内审时，发现公司的样件控制计划，试生产控制计划，生产控制计划，它们三者之间没有任何的区别，我觉得这样是不对的，但是这三者之间应有的区别是什么?各自的输入又有哪些?如何根据输入形成不同阶段的控制计划?。

样件控制计划，试生产控制计划，生产控制计划，

Prototype control plan: 在产品设计和验证阶段，关注的是产品的尺寸和性能，输入应该是DFMEA和特殊特性清单，技术规格书，图纸;

Pre-production control plan: 在过程设计和验证阶段，关注的是产品和过程的特殊特性，输入的是PFMEA，特殊特性清单和技术规格书，图纸;

Series-production control plan: 在量产阶段，是关注的是产品和过程的特殊特性，输入的是PFMEA，特殊特性清单和技术规格书，图纸;

Pre-production control plan&Series-production control plan的区别在于：Pre-production control plan的抽样的频度和检测的项目应该相对来说多一点，量产成熟稳定后，可适当降低检测频度和检验项目。

2.5 Prototype Build - Control Plan

Prototype control plans are a description of the dimensional measurements and material and functional tests that will occur during prototype build. The organization’s product quality planning team should ensure that a prototype control plan is prepared. Control plan methodology is described in Chapter 6. A Control Plan Checklist is provided in both Section 6 and Appendix A-8 to assist in the preparation of the prototype control plan.

The manufacture of prototype parts provides an excellent opportunity for the team and the customer to evaluate how well the product or service meets the Voice of the Customer objectives. It is the organization’s product quality planning team's responsibility to review prototypes for the following:

• Assure that the product or service meets specification and report data as required.

• Ensure that particular attention has been given to special product and process characteristics.

• Use data and experience to establish preliminary process parameters and packaging requirements.

•Communicate any concerns, deviations, and/or cost impact to the customer.

3.7 Pre-Launch Control Plan

Pre-launch control plans are a description of the dimensional measurements

and material and functional tests that will occur after prototype and before

full production. The pre-launch control plan should include additional

product/process controls to be implemented until the production process is

validated. The purpose of the pre-launch control plan is to contain potential

non-conformities during or prior to initial production runs. Examples of

enhancements in the pre-launch control plan are:

• More frequent inspection

• More in-process and final check points

• Robust statistical evaluations

• Enhanced audits

• Identification of error-proofing devices

4.7 Production Control Plan

The production control plan is a written description of the systems for controlling production parts and processes. The production control plan is a living document and should be updated to reflect the addition or deletion of controls based on experience gained by producing parts. (Approval of the authorized customer representative may be required.) The production control plan is a logical extension of the pre-launch control plan. Mass production provides the organization the opportunity to evaluate output, review the control plan and make appropriate changes. Chapter 6 and Appendix A-8 present Control Plan Methodology and a checklist to verify completeness.

一般来说，试产时的其他尺寸不需要监测，除非技术部门要求的，因为特殊特性里可能已经包括了很多尺寸了

量产时的抽样频率大小的确是依据试产的CPK情况来确定AQL的

先同意3楼和7楼的。。。。另外，样件控制计划，往往可能是手工件：即可能没有正式的工装、加工方法和检测手段等，而这些在试生产和生产中就可能有勒。控制方法自然就如楼上2位所言，与样件不一样。

个人理解：第一是样件与试生产件在过程控制中的检验容量、频率与批量生产的控制是有区别的，比如样件的检验容量一般是100%，而批量生产的产品只做首检、巡检、末检;

第二是样件与批量产品所使用的加工设备、工装可能会有变化，当然，这个不是绝对的，要根据贵公司的实际

样件的输入应是DFMEA分析的结果、特殊特性清单等。生产控制计划的输出应是现场的作业指导文件
