Abstract

An intelligent numerical control machining programming system and method for aircraft structural parts. The system employs an existing CAD / CAM system as a platform and comprises five major modules including a model detection module (2), a process scheme automatic generation module (3), a process resource and knowledge library management model (1), an automatic programming subsystem module (4) and a numerical control program intelligent optimization module (5). Being set up upon a three-dimensional model, the system gives a comparatively systematical and accurate reflection of and also support to the professional procedures of the numerical control machining programming for aircraft structural parts, and therefore, man-machine interaction operations required during the course of technological preparation and programming process can be reduced remarkably, unstable programs, prolonged programming periods and other such problems resulting from universal platform and human experience-based interactive programming are effectively solved, the efficiency and quality of numerical control machining preparation and programming can be enhanced significantly, and the levels of professionalism and intelligence of the CAD / CAM system are raised.

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. It was born and developed rapidly with the advent of the world's first three-coordinate CNC milling machine. Model the process of CNC automatic programming. Throughout its development, what drives this change is the requirement of vivid production practice for NC machining prog...
