3D Surface Roughness and Wear Measurement, Analysis and Inspection

Surface texture measurement – did you set the cutoff lengths properly?

Along with specifying the surface roughness with Ra (average roughness), one must establish the cutoff lengths used to measure the surface. A specification of Ra alone is inadequate, since measurement with different cutoff lengths may result in different measured Ra values.

Per the ASME B46.1-1995 standard, the long wave cutoff length must be specified on all drawings. Per ISO 1302-2002, both the long and short wave cutoff lengths must be specified…
