NC Milling Process Planning for Thin-Walled Parts with Low Rigidity

To solve the problems that the low rigidity thin-walled part is easy to deform in NC milling process and some parts of the complex surface is difficult to process, this paper points out the measures for increasing accuracy of thin-walled NC machining process from the selection of material and blank, the choice of machine tool, the determination and optimization of the clamping method, the choice of cutting tool, the determination of the tool path, the velocity field distribution of the cutter shaft and the modeling of motion constraint, etc. These theories and methods have certain guiding significance for the efficient numerical control milling of thin-walled parts and they can be used to guide the production practice.
