The article deals with relation identification of cutting time and morphology of tooled surface, expressed by surface roughness profile parameters - average roughness and creation of mathematical - statistical model of the investigated dependence.
Article deals with creation of mathematical - statistical model of cutting forces at turning of steel ISO 683/1-87 by means of regression and correlation analysis. It has been identified the significance of that factors that influence the investigated parameter. and Článok sa zaoberá vytvorením matematicko - štatistického modelu rezných síl pri pozdĺžnom sústružení ocele ISO 683/1-87 s použitím metód regresnej a korelačnej analýzy, ako aj identifikáciou významnosti týchto faktorov na skúmaný parameter.
