The invention provides a modeling method for dynamic
machining features of a complex curved surface and belongs to the technical field of CAD /
CAM. The modeling method for the dynamic
machining features of the complex curved surface comprises the steps that firstly, according to a selected
machining scheme, machining
intermediate state features corresponding to all machining stages in the curved surface machining scheme are defined; secondly, curved surface machining area division is conducted on each
intermediate stage feature according to selected machining devices,
cutting parameters and machining optimization objects of different machining stages, so that curved surface machining sub-features are obtained. According to the modeling method for the dynamic machining features of the complex curved surface, FunctionBlock is used as an information carrier of the curved surface dynamic machining features, when manufacturing resources are changed, an event triggering-responding mechanism of the FunctionBlock is utilized, a defined curved surface
feature modeling method in the FunctionBlock is automatically called, and the
intermediate state features of curved surface machining and curved surface machining sub-features contained by the
intermediate state features are updated in real time. By the adoption of the modeling method for dynamic machining features of the complex curved surface, the curved surface machining features can be dynamically updated according to the change of the manufacturing resources, and the modeling method is the key technology for achieving complex curved surface self-adaption optimized machining.
