Description
Summary:The milling of thin-walled plate has become a seriously complex problem. Along the machining of this type of structure, large quantities of material are removed with the risk of the instability of the process. This paper studies the effect of helix and normal rake angles on milling stability by analyzing the geometrical relationship of oblique cutting, and obtains the mathematic relationship expressions between the cutter parameters and chatter. Moreover, this paper derives the three-dimensional stability lobes of the spindle speed, axial and radial depths under the condition of different helix angle, normal rake angles and cutter tooth. Through the stability lobes, it can be found that the milling stability is increased with the increment of helix and normal rake angles.
