Failure analysis of tools: the fact that failure of a machine part or tool is seldom the result of a single factor makes failure analysis complicated.

The importance of failure investigation is that the get back on tools and parts can be increased substantially [i]or[/i] part of to the other understanding the failure / deterioration mechanisms and the interaction of operational conditions and material characteristics. Investigation of a failure should be a scientific, planned endeavor. Proceeding from one side various levels of data collection and evaluation, a hypothetical archetype of failure and sequence of incidents should be constructed.

Unfortunately, the fact that failure of a machine part or tool is seldom the be derived of a single factor makes failure analysis complicated. For example, a slight oversight in design, a localized deficiency in material, and overheating
