Abstract

The invention belongs to the technical field of aviation blade machining, in particular relates to an aviation blade machining method based on error compensation. The aviation blade machining method is characterized by comprising the steps of building of a milling physical simulation model, determination of a compensation scheme, milling of a blade through computer intelligent control, comparison after the error compensation and formation after adjusting correction. The milling physical simulation model is built, and the deformation quantity in the blade machining engineering is accurately forecasted according to an error compensation principle, so that the milling error caused by the deformation of the blade and a milling cutter is largely reduced, the blade machining precision can be effectively improved, and the working efficiency is enhanced; and the blade deformation is controlled through the cutting surface finite element analysis and the cutter path finite element analysis, so that the blade machining deformation quantity is reduced, the cost is decreased, and the machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of aviation blade processing, and in particular relates to a method for processing aviation blades based on error compensation. Background technique [0002] During the milling process of the aero-engine blade, because the milling track of the milling cutter is a helical line, due to the deformation of the blade, the tool deviates from the original milling track. Although the deviation is not very large, it still has a certain impact on the machining accuracy of the blade, which may cause deformation of the tool. Due to the deformation of the tool, the tool center shifts and the instantaneous milling force also changes, resulting in machining errors. Under the interaction force between the cutter and the blade, both of them undergo a large deformation. After the CNC machining and milling is completed, the blade is deformed due to elastic recovery, resulting in a decrease in the machining accuracy and surface...
