A non-iterative deformation error compensation method for thin-walled part

Abstract Thin-walled parts, which are widely used in the automotive and aerospace industries, always have a problem of low machining quality due to the force-induced deformation in the machining procedure. To solve this problem, a non-iterative deformation error compensation model based on the mirror principle is proposed. First, the milling force is reconstructed by introducing a comprehensive coefficient, which is used to establish the non-iterative deformation prediction model. Then, based on the mirror principle, the total compensation value is derived from the closed-form solution to build the error compensation model without iteration. Finally, the feasibility of the proposed models is verified through the flank milling experiment and simulation.
