Research of Surface Roughness Anisotropy

Research of Surface Roughness Anisotropy

The authors of the paper have investigated surfaces with irregular roughness for the purpose of determination of roughness spacing parameters perpendicularly to machining traces – RSm1 and parallel to them – RSm2, as well as checking the relationship between the surface anisotropy coefficient c and...
