Abstract: Engineering workpieces are designed, manufactured and measured to meet tolerance specifications of various geometrical characteristics (e.g., surface texture, size, angle, radius). After a workpiece has been manufactured, it is necessary to verify the derived characterization (tolerance) parameters to ensure it performs its designed functions. Though the designed functions of a workpiece are the comprehensive effect of several characterization parameters, surface texture is often the dominant one. The roughnes…
