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...
Many components used in the aerospace industry are usually thin-walled structures. Because of their poor stiffness, thin-walled parts are very easy to deform in the process of cutting. Due to the gradual reduced thickness during cutting, the end milling of thin-walled plate is a very complicated process. This paper proposes a new analytical deformation model suitable for static deformations prediction...
Chatter phenomenon often occurs during peripheral milling of thin-walled plate, which affect the quality of the finished part, the tool life and the spindle life. Therefore, it is necessary to avoid chatter with a suitable choice of cutting condition. Several stability models only emphasize the axial depth for chatter free machining. In this paper, it is shown that the radial depth is the same important...
With the development of the modern aircraft, the large-scale thin walled parts have been used in aeronautics and astronautics. In NC milling process, the thin walled plates are very easy to deform which will influence the accuracy and quality. From the point of view of theoretically and numerical calculation, the paper proposes a new analytical deformation model suitable for static machining error...
