The Analysis of the Machining Influence of the Surface Layer on Durability

Abstract:

The paper deals with the influence of the properties surface layer of notched components. This material is widely used in the automotive industry. This material is subject to different kinds of processing, and therefore present a different quality of the surface layer. For many manufactured components, we find diverse types of notches, such as slots, recesses and holes. They are the place where is stress concentrated, so called the macroscopic stress concentrator. When we focus more on the surface profile, we find the diversity of technologies in the surface, which creates different sizes and shapes of microscopic notches. In these places, there is a higher risk of the destruction of the components. Many designers prescribe unnecessarily high surface quality. It is important to maintain adequate quality of the surface to achieved high durability.
