Study on the Effects of the Machining Parameters on Surface Roughness and Vibration in Milling 34CrNiMo6 Steel

In this study, 34crnimo6 alloyed steel was machined with tialn coated carbide cutting insert and the vibration and surface roughness during the process were measured. experiments were carried out through three different cutting speeds (90, 120 and 150 m / min), three different feed rates (0,12, 0,17 and 0,22 mm / tooth) and three different depth of cuts (1, 2 and 3 mm) based on 27 full factorial experiments. the experimental results were statistically evaluated using analysis of variance (anova) and mean effect plots. the test results indicated thatthe most effective cutting parameter on surface roughness was feed rate while the most effective parameter on vibration was cutting speed. the cutting speed and depth of cut were not exhibited a meaningful effect on the surface roughness and the vibration was increased with increasing cutting speed values.
