摘要

We describe and investigate a method to monitor flexural and torsional vibration of the main axle in a numerically controlled machining tool. The method uses the Doppler-frequency shift of a laser beam. More specifically, the axle vibration is measured using the differential method of two parallel beams and Mach-Zehnder heterodyne interference. The two beams irradiate a symmetrical section of the main axis with equal light intensity. The resulting Doppler frequency shift of the scattered light is affected by both flexural and torsional vibration. The scattered beam interferes with a reference beam. The interference signal after mixing is measured with a photoelectric detector. By using frequency discrimination, we can decouple the transient rotation speed from the torsional vibration of the machine tool. Our experimental results indicate that the transient linear velocity deviation of our measuring system is less than ±0.3 mm/s. Our study shows that it is possible to measure the vibration in a machine tool spindle at high speed rotation with good reliability.
