Abstract

A new multi-probe method was proposed for cylindrical figure measurement of heavy and large sized cylinders. Six displacement probes, which are placed in three cross-sections around the cylinder workpiece, are employed in this method for the purpose of separating the cylinder figure errors from the motion errors of the cylinder spindle and the probe carriage. The probe numbers in the three cross-sections are three, two and one, respectively. The roundness profiles at each position along the central axis of the cylinder are measured first using the three probes placed in the same cross-section based on the conventional three-probe method. The deviations of average radius and the horizontal and vertical straightness of the central axis of the cylinder can also be evaluated through employing the outputs of the six probes, leading to a complete figure measurement result The measurement is not affected by the scanning motion errors and the probe zero-adjustment errors. Taper-shaped cylinders can also be measured with this method. A prototype instrument capable of measuring a large cylinder with a length of up to about 1,650mm was designed and built to realize the proposed multi-probe method. Experiments were also carried out to confirm the effectiveness of the instrument.
