Abstract
In thin-walled Titanium Ti6Al4V machining, vibration is the dominant factor affecting the quality of components. Excessive vibrations can generate chatter, this condition occurs because it is not suitable in choosing machining parameters. Chatter is not expected because it causes dimensional errors, rapid tool wear and poor surface finish. This experiment tries to identify chatter-free conditions with the appropriate parameters. Uncoated carbide is used as a cutting tool with a diameter of 10 mm and machining under the MQL system with coconut oil as a cutting fluid. In the result of the milling showed if this machining is free of chatter, where from frequency was achieved is not equal to the natural frequency from simulation, then this is also approved from result surface roughness and surface photography. In surface roughness result, the value is smaller than minimum critical amplitude, where good result in high value of the cutting speed and small feed rate and result of the surface photography was identified no severe surface condition along thin-walled. The experiment also calculated for non-thin-walled Ti6Al4V as evaluation, where the result of both acceleration and surface roughness was obtained smaller than milling thin-walled.
