Definition
In the field of precision engineering and metrology, inspection can be defined as the set of hardware, software, procedures, and activities that can provide measurements of geometric characteristics of physical manufactured products.
Such geometric characteristics can refer to absolute dimensions (e.g., diameter) and form (e.g., free-form surfaces), to tolerances of dimensions and form (e.g., flatness), as well as surface parameters (e.g., average surface Roughness).
Theory and Application
The main goal of inspection is to ensure the functionality of workpieces, products, and testing devices and thus ensuring economical value of products. As such, the main objective of inspection in the field of precision engineering and metrology is to quantify the dimensional characteristics of components by means of measurements and to compare the results of those measurements with the product specifications (ISO 8015 2011).
Inspectionis today very closely connected into the...
