Approximation trend undulations extended surfaces on the results of calculation of roughness parameters
From measurements of the roughness profile ordinates the possibility of interconnecting statistical measurements, which are understood as a numerical calculation of surface quality characteristics - roughness adopted for the bulk, and the simultaneous computation of one (or more) additional features - waviness having the main known statistical or deterministic relationship. For assessments of the quality of simple surfaces of extended products proved the possibility of two-dimensional analysis of roughness when moving to independent linear induction based contact sensor with extended dynamic range for measuring roughness ordinate approximation trend waviness on the results of calculation of roughness parameters on the standard linear finite bases.
