Abstract

The invention relates to an intelligent numerical control machining programming system and an intelligent numerical control machining programming method for aircraft structural parts. According to the system, an existing CAD / CAM (Computer-Aided Design / Computer-Aided Manufacturing) system is taken as a platform; the system comprises a model detection module, a process scheme automatic generation module, a process resource and knowledge base management model, an automatic programming subsystem module and a numerical control program intelligent optimization module. The system is established on the basis of a three-dimensional model, the numerical control machining programming specialization process of the aircraft structural parts is relatively systematically and accurately reflected and supported, the man-machine interaction operation required in the technological preparation and programming process can be greatly reduced, the problems of unstable program, long programming period and the like caused by interactive programming based on universal platform and artificial experience are effectively solved, the numerical control machining preparation and programming efficiency and quality can be obviously improved, and the specialization level and the intelligence level of the CAD / CAM system are promoted.

Description

technical field [0001] The invention relates to an intelligent numerical control machining programming system and method for aircraft structural parts, which is applied to the programming of numerical control machining programs for large overall structural parts of aircraft, and improves the automation and intelligence level of numerical control programming, so as to shorten the numerical control programming cycle of aircraft structural parts and improve the Machining efficiency of structural parts. The technical invention belongs to the field of aircraft digital manufacturing technology. Background technique [0002] The development of CNC programming technology has a history of more than 50 years.
