Abstract
Spark-erosion has a marked effect on both surface hardness and fatigue strength of tool steels. This paper gives the relations between the hardness depth, the surface finish parameters and the decrease in the fatigue strength of a 90 MnV8 tool steel for various rates of spark-erosion. Both hardness and maximal depths proved to be of great significance regarding the decrease in the fatigue strength due to spark-erosion. To acquaint the designer with the effect of spark-eroded notches on the fatigue strength; a comparative study with ground notches is also presented. A “Process Factor” is introduced to assess the fatigue strength reduction factors of spark-eroded notches with various shapes.
