中文摘要 | 「製程失效模式與效應分析」(PFMEA-Process Failure Mode and Effects Analysis)是失效模式與效應分析(FMEA)技術的延伸,FMEA依目的可分為「設計FMEA」與「製程FMEA」。「設計FMEA」是運用在新產品的研發設計,藉此來提升產品的可靠度,進而預防產品因設計變更所增添的機會成本。而「製程FMEA」則是當新產品進入量產前,在製程的設計與流程規劃中,如何預先防範製程可能造成產品損壞或設備的故障,甚至可能危害操作人員的安全,此乃如何確保並提高生產過程可靠度所需探討之重點。又於製造過程中,何者是關鍵製程?如何決定?又如何保證經此製造過程所生產的產品,其可靠度能滿足顧客需求?諸如此類,皆是「製程FMEA」所需探討之主題。 本文藉由製程FMEA之實證,探討汽車引擎機油泵於量產裝配前,經由製程FMEA團隊成員的腦力激盪,決定機油泵的生產流程,再評估每一細項流程的風險優先度(Risk Priority Number, RPN)。透過製程FMEA技術,在產品符合顧客滿意度最大的原則下,使製程設計能最適化。 |
英文摘要 | Due to the purpose of reliability promotion and to reduce redesign cost, enterprises use the methodology of failure mode and effects analysis (FMEA) to develop new product. However, there lays sequential considerations need to be taken into account, such as procedure arrangement for mass production, precautious recovery for product damage and equipment break down, and a critical first aid management for operators to reduce harm in process. The FMEA of process has ensured the reliability of product in process. This research is used FMEA to study the key assembling process of auto engine oil pump before in mass production. In order to find the critical points and sequence of process improvement, FMEA team under member meeting to find risk priority number in risk evaluation adopts a brainstorming. In this meeting, the FMEA team selects the bigger risk priority numbers as the key process or proposes the critical points for quality control. After adopted the above improvement, which under the continuous improvement of Deming PDCA (planning, doing, checking, and action), it is available to revalue the RPN of engine oil pump assembling process. In addition to revaluate the index of RPN to confirm upon improved result as for dealing with modifying strategy feasibility in the secondary item of RPN. Product manufactured by the most appropriate process may be achieved to the maximum satisfaction of customer requirement. |
