| Abstract: | A method of on-line measurement of contouring error on numerically-controlled machine tools or machining centers is a simple, high-speed and economical. It don't use coordinate measuring machine that is expensive. Infulence of straight line moving errors of numerically-controlled machine tools or machining centers to on-line measurement precision of workpiece contouring error is analysed. The geometric moving errors of a machinine center are measured. A method of improving on-line measurement precision of workpiece contouring error is advancing by means of removing influence of geometric moving errors of numerically-controlled machine tools or machining centers. The on-line measurement precision of workpiece contouring error is improved using the method according to the experiment results. |
