[Abstract]:In order to solve the problems such as low programming efficiency, large workload and unstable quality of NC (NC) machining for aircraft structural parts, an automatic extension technology based on corner surface is proposed, and the machining model is established based on process knowledge. It lays a foundation for the realization of automatic programming technology of corner NC machining. Firstly, the concepts of rotation angle, corner surface, corner machining model and corner machining interference domain are defined, and then the automatic extension, calculation of side rotation surface and tangent element, and construction of interference domain are given to realize the construction of corner machining model. Finally, the automatic programming system of corner NC machining is developed based on the above research and applied to the production of certain aircraft structural components. The application results show that this technology can significantly improve the efficiency and quality of NC machining programming. Reduced programming effort.
