Why Measure Components
Component measurement can be used for a number of purposes, the most frequent being:
- To make sure that a component being developed conforms to set parameters. For example, if a plastic part has to interact with others, e.g. as part of a complex assembly, then it must fall within predetermined tolerances.
- To see how an existing product is performing as it is subjected to use
- To ‘reverse engineer’ an existing component. Measurements are used to create an accurate drawing (such as a 3-Dimensional CAD file) from which additional components can be manufactured.
- To make sure that a measurement device (such as a digital Vernier), jig or gauge that is used to monitor the dimensions of parts in production is within tolerance. This is called fixture verification
