Question

Is assessment length greater than the transaction length in surface finish measurement? Why?

Answer 1

Is assessment length greater than the transaction length in surface finish measurement because in assessment length we have to Write by Hand on Any Copy And transaction length we have to do in Computers with Fast

Answer 2

Surface roughness often shortened to roughness, is a component of surface texture. It is quantified by the deviations in the direction of the normal vector of a real surface from its ideal form. If these deviations are large, the surface is rough; if they are small, the surface is smooth. In surface metrology, roughness is typically considered to be the high-frequency, short-wavelength component of a measured surface. However, in practice it is often necessary to know both the amplitude and frequency to ensure that a surface is fit for a purpose
