Spc | Arithmetic mean value of peak curvature |
Sa | Mean arithmetic height of the scale-limited surface area |
RSm | Mean spacing of the profile elements |
Ra | Arithmetic mean value of the height |
Sdr | Developed transition area ratio of a scale-limited surface |
Str | Aspect ratio of the surface texture |
Sz | Maximum height of the scale-limited surface |
Rz | Maximum height |
