In the study, the optimum cutting parameters were determined by studying the effects rates of the independent variables (cutting speed, progress amount, cutting dependency and line-end radiation) used during the cutting of the C45 manufacturing steel, depending on variables (surface smoothness). Tornating tests were carried out according to the surface response method L27 orthogonal (orphological) directory. As independent variables, 3 different cutting speeds (160 m/min, 260 m/min and 360 m/min), the progress amount (0.05 mm/dev, 0.18 mm/dev and 0.31 mm/dev), the cutting depth (0.1 mm, 0.3 mm and 0.5 mm) and the set end radius (0.4 mm, 0.8 mm and 1.2 mm) were used. The analysis of variants examined the effects of independent variants and the effects of interactions on dependent variants. As a result, the most effective independent variable on the dependent variable is determined to be the progress amount and the set end radio, respectively, while the effect of the cutting speed and the cutting depth is determined to be low. The amount of progress increased, the dependent variable increased, the team end radiation increased and decreased.
