Iterative Algorithm for Establishing the Optimal Compensation Model of Blade Cutting Path Based on Finite Element Analysis

Abstract:

Blade deformation during its machining is a key problem in aviation manufacturing. Machining error of a low rigidity blade caused by cutting force reduces its processing precision. And this kind of error is difficult to predict and control. In the paper, Finite Element Analysis is used to simulate blade machining process. The errors at sample points are gotten and used to evaluate the change of tool path. An optimal compensation model of blade machining path is put forward to consider the coupling effect between blade deformation and cutting force in multiple feeds. And an iterative algorithm is also presented to solve the optimal model. Thus, the object is achieved to reduce the blade machining error to a satisfying extent.
