FMEA failure mode analysis of how to do?
? FMEA failure mode analysis of how to do FMEA failure mode analysis, as a precaution special tools, the key head to the find, review product / the whole process potentially invalid and adverse effects; seek solutions to prevent or reduce the potential void created and continue to improve.
According to FMEA can identify and assess the design or engineering project, there will be hazards and shortcomings of the way, and a clear improvement measures to remove or reduce the potential of generating invalid and thus preventive measures to minimize the cost disadvantages of various types of fees to ensure goods / services with outstanding characteristics.
FMEA failure mode analysis of the implementation process:
1, drawing flow charts and risk assessment.
2, a clear analysis of each level of the whole process.
3, each of which established the whole process of quality, dimensional tolerances and so on.
4, a block diagram of the production process is made.
5, for each production process flow, poor way of example generated.
6, resulting in poor carding poor way of reason, the other half is selected as a reflection of the poor way.
7, with Plato will analyze the sake of the poor generated.
8, because of the poor way and included FMEA reports.
9, to the level of hazard, occurrence frequency, detectability, the level of understanding of the equipment is the criterion, to carry out the review level disadvantages embodiment, points Ⅰ, Ⅱ, Ⅲ, Ⅳ like.
10, estimates the serious consequences of the poor, and today's generation probability of detectability, estimates RPN.
11, to establish how to improve the serious consequences, produce and probability of detection.
12, implementation of program improvement plan.
13, collecting statistical data, implement improvements and to determine the actual effect.
14, revised FMEA document, based on improved practical effect rearrangement RPN.
15, from step 12 if necessary to the beginning of a new and improved circulation system.
FMEA failure mode analysis as a basis for risk management and control of technical way, this is a targeted statistical analysis method elite team-oriented in nature, able to identify and reduce risk. If the design and development of common failure causes and consequences of the process of hair that is too late, or is found to only commodity on the market, then the repair and correction countermeasures in this case consumes a great time at the cost of fees and above. The FMEA? Into the early part of the entire process of product development, and conducive to the identification of goods and the whole process of risk, and decreases according to adopt appropriate countermeasures or even prevent shortcomings.
FMEA failure mode analysis of supply is no problem for the use of goods and improve customer satisfaction is very necessary. This reduces costs and prevent common failures and warranty costs and product recall credibility or common faults related to common failure is closely related to the cost of fees.
