Abstract

For the calibration of rectangular and trapezoidal profile roughness specimens, stylus tip will increase profile peak width and decrease valley width, which may cause the Ra changes (either increase or decrease, depends on the profile shape). Sometimes the changes are even larger than the calibration uncertainties. That raises a question as to whether the measured surface parameters should be corrected for the significant tip size effect.
