ABSTRACT:
A method of determining parameters for a burnishing operation includes: using a rolling burnishing element to burnish at least two segments on a selected surface of a material sample, the segments having a common width and overlapping each other by a preselected overlap value; measuring the resulting hardness of the surface; and selecting a working overlap value for a subsequent burnishing operation on a workpiece, based on the measured hardness.
