“…The measuring signals of displacement simultaneously contain three elements: the straight-line motion error of the slide track, the profile error of the gyrator, and the rotating shaft roundness error in revolution. Several methods have been investigated by researchers for separating these three errors, such as the multi-step method [1,5], the reversal method [1], the mixed method [6], the three-point method [7][8], and the four-point method [9].…”

This report examines the measurement of rotational accuracy for machine tools, using the concept of cylindrical error on linear motion. This measurement can be divided into three steps: first, separate the straight-line motion error of the slide track from motional parts of the machine tools; next, choose the basic cross section of cylinder and estimate the errors of cross sections through the three-point error separating method; third, estimate the roundness error of each cross section projected onto the perpendicular basal plane according to the measurement of straight-line error; finally, calculate the value of the radius of the minimum circumscribing cylinder in order to evaluate the rotational accuracy of multi-point cutting machine tools.

The three-point method is a technique that uses three displacement sensors to separate the out of roundness of a reference sphere or cylinder as well as the spindle run-out. This method has high potential for ultra-high-precision measurements. However, applications of the three-point method have been impeded because the setting angles of the sensors have not been clearly established. In this paper, the effects of uncorrelated noise in sensor outputs on the calculation results of the roundness are analyzed by applying the process of the three-point method as a digital filter. Then, the optimum sensor angles, which minimize the effects of the noise, are computed where there is uncorrelated white or pink noise in sensor outputs. In addition, the effects of correlated noise in sensor outputs are analyzed.
