Measuring Surface Finish Surface Texture Parameters Sample Filtering Modern surface texture measuring instruments record the stylus movement over the evaluation length electronically and can produce output readings to a significant level of detail. The instruments measure the roughness variations and the wavine...
The principal ISO standard that specifies syrface roughness is ISO 1302 and defines the surface roughness symbology and additional requirements for engineering drawings. The details in ISO surface finish standards relate to surfaces produced by abrading,

A surface finish or surface roughness probe (10) comprises a deflectable stylus (18) associated with a skid (14). It is mounted in a coordinate measuring machine (CMM), which drags the skid (14) and stylus (18) along a surface (24) to be measured. Stylus deflections relative to the ...

Being able to quantify a surface finish is both a complex and necessary task. While surface topography relates to a three-dimensional property, the most accepted surface measurement parameter is average roughness (Ra), a two-dimensional parameter. Ra is relatively simple to quantify and can be me...
