A method of on line measurement of contouring error on numerically controlled machine tools or machining centers is characterized by simplicity, time saving and economg. It don’t use coordinate measuring machine that is expensive. Infulence of straight line moving errors of numerically controlled machine tools or machining centers on on line measurement precision of workpiece contouring error is analysed. A method of improving on line measurement precision of workpiece contouring error is advanced by means of removing influence of geometric moving errors of numerically controlled machine tools or machining centers. The experiment results indicate that the method used can improve the on line measurement precision of workpiece contouring error.
