Process Signatures correlate the thermo-mechanical load within the workmaterial during the manufacturing process with resulting modifications of the material properties. In the case of hard turning, new mechanical and metallurgical material properties in the workpiece surface may severely influence the structural stability and fatigue resistance.

This work investigated whether the concept of Process Signatures is applicable to hard turning of steel AISI 52100. Experimentally obtained surface properties are correlated with numerically simulated material loads, which the surface was subjected to during turning. The process was analyzed under consideration of different tool wear states in order to assess the material modifications for different thermo-mechanical loads.
