Popis: Machining processes are subjected to machining vibrations and specially to chatter. This self-excited vibration determines the productivity of the processes. Over the years, many studies have been developed analysing the influence of the tool and machine structure on chatter. However, not many studies have been carried out on the workpiece material influence on chatter. The workpiece material is a characteristic settled form the drawings that cannot be changed. Due to this, in which extent the SLD (Stability Lobe Diagram) is affected by the workpiece material parameters is essential to increase the chatter knowledge. To that end, an experimental study of the workpiece influence on chatter was carried out, stablishing specific cutting force and Process Damping Wavelength as the main cause parameters of this influence. In order to obtain the necessary data to demonstrate the influence of both parameters on SLD, some experimental tests were carried out milling 34CrNiMo6 and Al 6082. Thus, these results showed how the SLD is affected.
