Adaptive NC machining technology has obvious advantages in the machining of high-powered Aeroengine products and prolonging life overhaul machine products

which is based on flexible manufacturing and adaptive control. Adaptive control factors include stock

error

precision

cutting speed

feed speed

cutting force and so on

in the course of NC machining

which mostly embody four aspects: adaptive control for space geometrical position of workpiece

adaptive control for clamping position of parts

adaptive control for cutting load and adaptive control for machine tool production operation. In the paper

the aero-engine product adaptability processing technology and its key technologies are comprehensively elaborated

and the application of adaptive numerical control processing and control elements are discussed. Finally

it is pointed out that adaptive NC machining technology is an effective method to improve the machining efficiency and accuracy of NC machining

and the adaptive NC machining technology of intelligent control will become an important development direction of intelligent manufacturing.
