The invention discloses a preparation
system of quick
numerical control machining of complex parts of an
airplane and a method. The
system takes the existing CAD /
CAM system as a platform, and comprises a technology resource and
knowledge base management module, a quick blank generation module, a part classification and technical scheme analysis module, an
automatic programming module, a quick tool generation module, a strain analysis and
deformation control module, a front and rear
process module and a technology data generation module. The system is built on the basis of a three-dimensional numeric part model, systematically and exactly embodies a specialized flow path for supporting the
numerical control machining technology preparing and the
programming of the complex parts of the
airplane, can greatly reduce man-
machine interaction operation required by preparing technology and
programming, effectively solves the problems of the unstable programmed procedure and the unreasonable scheme design of the
machining technology caused by the lack of the experience of process operators, and the like, can effectively control the deformation quantity during and after machining the parts, can obviously improve the efficiency and the quality of the
numerical control machining preparing and the
programming, and improves the professional level and the intelligence level of the CAD /
CAM system.
