Abstract

The invention provides a self-adaptive regulation method, device and electronic equipment for blade machining process, belonging to the technical field of aero-engine milling. The provided self-adaptive control method for a blade machining process includes: acquiring profile feature data of a blade to be processed, and constructing a prediction model according to the profile feature data. The prediction model is compared with the pre-stored theoretical model, and the first error data of the theoretical model and the prediction model is calculated. Through the obtained first error data, the tool path of the blade to be processed and the milling parameters of the machine tool are adaptively adjusted, which improves the processing quality and accuracy of the blade and reduces the damage and deformation of the parts.

Description

technical field [0001] The invention relates to the technical field of aero-engine milling, in particular to a self-adaptive regulation method, device and electronic equipment for blade machining procedures. Background technique [0002] The blisk blade of aero-engine is an important part of aero-engine. It is a new structural component designed to improve the performance of aero-engine. The working efficiency of aero-engines can also enhance the working performance of aero-engines, so it has been widely concerned and used by the aviation industry of various countries. The blades of aero-engines are thin-walled, complex and difficult-to-machine parts, and problems such as easy deformation, low machining efficiency, and poor machining quality restrict their development during the machining process. The shape of the free-form surface of the blade is very complex, and its processing accuracy is very high. The unreasonable selection of milling parameters can easily cause damage...
