【正文】 ，一個回形針包括兩個互相貼合的金屬表面，通過金屬絲的彈性來夾緊紙張。 ? As you distort the paper clip away from its equilibrium shape, by spreading the two surfaces apart, it experiences restoring forces. 當(dāng)你將回形針的兩個表面分開，使之變形，會有一個回彈力。 ? These forces tend to return the paper clip to its equilibrium shape and push the two surfaces together. 這種力量會導(dǎo)致回形針回復(fù)到一個平面，并將兩個表面合在一起。 ? A test engineer determined that this change would result in only 2 percent decrease in spring action gripping. 一個測試工程師確定，這種更改只會降低彈力的 2%。 Basic Customer Requirements for a paper clip 對于回形針，顧客的基本要求。 ? Basic Function: Holds papers securely 基本功能：安全的夾緊紙張 ? Maintains integrity of the stack of paper 保持一堆紙張整齊 ? Does not catch, mutilate, or tear papers 不能卡住或撕破紙張 ? Holds a thick set of papers 夾緊一摞厚紙 ? Is easily inserted. 能輕松插入 ? Safe to use 使用安全 ? Does not get tangled with other clips in the box 在盒子里，不能和其它回形針發(fā)生干涉 ? is light weight and requires less postage 輕量，并且需要較少的郵費 ? Is cheap 便宜 ? Is durable—does not rust 耐用，不能生銹 Block Diagram 簡圖 DFMEA ? Develop a DFMEA to determine what are the risks in using this design with the new changes ? 開發(fā)一個 DFMEA以確定這個新的更改所產(chǎn)生的設(shè)計風(fēng)險。 DFMEA ? Requirement: Does not catch, Mutilate, or tear papers ? 要求：不能卡住或撕破紙張 ? Team Exercise 小組測試 ? Develop the branch in the DFMEA for this requirement of the basic function of the item: paper clip ? 以以上要求，開發(fā)一個 DFMEA。 DFMEA ? Requirement： Does not catch, Mutilate, or tear papers. 不能卡住或撕破紙張 ? Failure Mode: Paper Clip catches, mutilates, or tears papers in normal use, on insertion, or on extraction. 在正常的插入或拔出過程中卡住或撕破紙張 with small stack of paper: the sharp ends of the clip dig into the papers when it is removed. 對于一小摞紙張：回形針的尖端會戳進(jìn)紙張 with large stack of paper: the clip either twists badly out of shape or files off the pile and the sharp ends of the clip dig into the papers. 對于一厚摞紙張：回形針既會彎曲變形，又會讓文件散亂，而導(dǎo)致尖端會戳進(jìn)紙張。 Sharp ends 回形針的尖端 Paper Clip—DFMEA Process Flow 過程流程 ? Operation 10: receiving (wire and coatings) 材料接收 ? Operation 20: Receiving Inspection 進(jìn)貨檢驗 ? Operation 30: Uncoiling and straightening 展開拉直 ? Operation 40: Coating—Future 涂覆 —后續(xù) ? Operation 50: Curing—Future 加工 —后續(xù) ? Operation 60: Cutting 切斷 ? Operation 70: Bending 彎曲 ? Operation 80: Unit Packaging 單只包裝 ? Operation 90: Pack and Ship 包裝發(fā)運 PFMEA ? Exercise 測試 ? Conduct and Review the PFMEA and Control Plan 實施并評審 PFMEA和控制計劃 Conclusions 結(jié)論 ? The FMEA process is critical in assuring that all areas of the product and process design (including interfaces and environment) have been evaluated and all potential failure modes have been mitigeted. ? FMEA過程決定于確保產(chǎn)品和過程設(shè)計的所有區(qū)域（包括接口和環(huán)境）都被評審，并且所有潛在失效模式都已經(jīng)被減輕 ? The 4th edition improvement will aid in applying FMEAs at suppliers and reduce some of the auditing issues in relation to FMEAs. 第四版 FMEA的改進(jìn)將會幫助供應(yīng)商對 FMEA的應(yīng)用，并且減少一些對 FMEA相關(guān)的審核。 Questions？ 問題？ 感謝您接受本次培訓(xùn)！ 如果您對本次培訓(xùn)有任何建議或意見，請向您的培訓(xùn)師提出，我們將認(rèn)真的考慮您所提出的任何疑問，以不斷改進(jìn)我們的培訓(xùn)質(zhì)量！ 謝謝觀看 /歡迎下載 BY FAITH I MEAN A VISION OF GOOD ONE CHERISHES AND THE ENTHUSIASM THAT PUSHES ONE TO SEEK ITS FULFILLMENT REGARDLESS OF OBSTACLES.
