Through the example of ultra-thin wall parts to start on multi-axis high-speed processing, in order to beam between the rib parts, for example, it is a model of civil aircraft parts on the vertical tail structure. The body parts from the process of analysis, technology selection of programs, positioning and clamping NC programming technology point of view, to set such a key part of the CNC machining techniques. In the actual application in the production of product quality, production efficiency has received good results.

By discussing the ultra thin parts processing, multiaxial high-speed rib here to support beam for example, it is the parts of a type of civil aircraft parts used in vertical rudder. From the analysis of technology, the text parts process scheme, selected clamped and CNC programming techniques, etc., to these parts of nc machining key technology. In the actual production of application of product quality, production efficiency has received good results.
