摘要：
Aiming at the nonlinear error caused by linkage between the rotating shaft and the translational axis for five-axis Machine with dual rotary table, an analytical model for real-time predicting and compensating the nonlinear errors was proposed. Based on the error distribution in classical post processing, the nonlinear error model of harmonic function analysis was established. The analytical expression of the model was used to quickly predict the nonlinear error between two tool points, and the real-time error of the intermediate interpolation points was compensated. The Maltlab simulation analysis for the tool position file of an impeller part was carried out, and the simulation results verified the effectiveness of the proposed algorithm. © 2020, Editorial Department of CIMS.
