AB Machining belongs to the basic and permanent manufacturing technology also on the present time, despite there was an idea (theoretical considering) in the publications of many experts in moulding and casting at the turn of the 70th and 80 years, that the machining could be replaced for the most part by accurate methods of casting or moulding. Although the material losses have been reduced in recent years due to approaching of components' size prepared by moulding or casting to the size desired by technical drawing, it is not possible to achieve the required accuracy of dimensions and shapes. The paper deals with statistical methods application to the evaluation of the maximum height surface roughness profile Rz and mean height surface roughness profile Ra in relation to the feed, cutting speed and depth of cut in longitudinal turning of steel C45. The main part of the paper is to demonstrate the procedure of statistical processing of experimentally obtained data in order to create a prediction model and compare it with the theoretical calculation formulas.
