This paper presents a kinematics detection and evaluation method for tool axis direction error of five-axis machine tools. By measuring the trajectory errors of two tool center positions corresponding to two different tool lengths, the tool axis direction error can be obtained by combining the two measurements. Compared with the evaluation method in ISO10791.6.2014 which can only evaluate the tool center position errors corresponding to a single tool length, the proposed method can infer the processing accuracy corresponding to different tool lengths and to evaluate the comprehensive accuracy of five-axis flank milling. The proposed method is verified through simulations and experiments on a five-axis gantry machine tool.
