Abstract: This study investigates the effect of tool wear on the rolling contact fatigue performance of superfinish hard machined surfaces. The rolling contact fatigue test results indicate that the flank wear width can contribute to the prediction accuracy of fatigue life model for the CBN tool with a tool nose radius of 0.79 mm. If the relationship between tool wear and the residual stress distribution and the relationship between tool wear and the micro-hardness distribution are established, it is expected that tool wear can contribute to the prediction accuracy of fatigue life model for more general conditions.
