The techniques about intelligent NC programming of aircraft integral panel are discussed according to the aircraft panel characteristics
typical machining process route and problems in NC programming. The techniques include the construction of the intelligent NC programming system of air craft integral panel
comprehensive knowledge representation of NC machining
slicing recognition of generalized pocket
automatic cutting tool selection based on geometrical characteristics and automatic sequencing based on knowledge reasoning. By using the above techniques
the rapid NC programming system of aircraft integral panel is developed.
