Question
1. Describe the main uses to which a completed FMECA can be applied.
2. Describe three methods that can be used to analyse and improve the processes that will be used for the manufacture of a new product design.
3. Explain why the actual mechanical strength of engineering components is very much less than the theoretical strength. How does this difference affect the predictability of strength?
4. Briefly describe the three most common causes of strength degradation of mechanical components. Give examples of each, with descriptions of methods used to prevent or reduce the chances of failure.
Explanation / Answer
1.FMECA has many uses. Examples include evaluating system reliability, evaluating hardware and software interfaces, identifying potential design defects and safety hazards, simplifying maintenance, and trouble-shooting. It is also useful for rating alternative solutions to a problem. FMECA produces and uses a lot of product/system data that must be distributed to many users in the development process. To avoid loss of valuable information about the design, this information must be carefully stored and distributed. Engineers must be able to see what changes were made to previous versions. As designs change, new revisions of FMECA analysis results will be created and modified. They too will have to be stored and be made available for future use. An EDM/PDM system can be used to manage the storage, access and distribution of FMECA data.
