Track: Manufacturing and Design
Abstract
The lifetime of a mechanical system is greatly influenced by surface state in service and the operating conditions such as friction and lubricantion. So the proper functioning of in service pieces depends heavily on the quality of their machinings as well as their finishes. This quality can be approximated by the fractal dimension "D", this latter is a major parameter for the automotive industry because it helps differentiate the gloss to the treated surfaces. It varies within 2
