The shape and size of irregularities on a machined surface have a major impact on quality, performance (leakage), and longevity.

In order to control the manufacturing process or predict a component’s behaviour during use, it is necessary to quantify surface characteristics by using surface texture parameters.

Amplitude Parameters are measures of the vertical characteristics of the surface deviations.

Part 5 of our video series on Surface Finish will discuss amplitude parameters. The full table of contents is below:
