Description

technical field

[0001] The invention relates to a numerically controlled machining test model of aircraft structural parts, in particular to a CAD (Computer Aided Design) / CAPP (Computer Aided Process Planning) / CAM (Computer Aided Process Planning) / CAM (Computer Auxiliary processing) software performance test model, specifically an integrated aircraft structural parts CNC machining capability test model and its application. Background technique

[0002] Aircraft structural parts are an important part of the aircraft body skeleton and aerodynamic shape, mainly including frames, beams, ribs and other types. The use of the overall structural parts of the aircraft greatly reduces the number of aircraft body parts, reduces the assembly workload, and significantly improves the manufacturing quality of the aircraft. The structure of aircraft structural parts is complex, with many processing features, including a large number of free-form surfaces, intersecting features and special ...
