There are many examples of feedback due to improper product design. Product failure can be caused by a series of errors during design, production, material supply, quality control, distribution, and other production cycle processes. FMEA is a way to identify possible mistakes and defects during the design and construction process. There are a total of two categories of FMEA: DFMEA and PFMEA. In DFMEA that tries to identify technical defects in production, reduce product life, safety, and standards resulting from:
- Material specifications
- The geometry
- Connect to other components and systems
- It has engineering noise
PFMEA seeks to identify defects and defects that affect product quality, reduced process reliability, customer dissatisfaction, safety, or environmental hazards such as the following:
- Human Factors
- Procedures related to the process
- Materials used
- Used machines and devices
- Measurement systems affecting acceptance
- Environmental factors affect process performance
Why do the FMEA?
In general, the sooner the cause of the failure is identified, the lower the cost to the manufacturer. The later the failure is detected, the higher the costs will be exponential.
When is FMEA?
- Design a new product, process, or service
- There is a program to change the existing process with a new method
- Our goal is to improve the quality of a specific process
- Our need is to identify and correct process defects
In addition, it is possible to execute FMEA while servicing the product. Click here for more information on fault analysis in engineering components, equipment, and structures.
