The present invention relates to an error compensation based corner processing precision control method and, more particularly, to a method for controlling corner processing precision based on error compensation. The invention is designed to solve the problems that the processing precision in prior art is low, the requirements for the machine tool and the numerical control system are high and the error is large. The method comprises the following steps: 1) establishing a milling force model for corner processing; 1A) establishing a micro-element milling force model; 1B) establishing a milling force model for the corner processing process; 2) establishing a cutter deformation model according to step 1; 3) conducting error iterative compensation to the cutter compensation model established in step 2 for the corner processing cutter path after compensation. The present invention facilitates the optimization of geometric kinematic errors, milling force errors, and thermal deformation errors in corner processing.
