<p>A three-point method has been used to separate the roundness profile of a workpiece and radial motions of a turntable. First, weighted addition is used to extract the roundness profile, and then, inverse filtering is used to recover the original roundness profile. The three-point method works well in the low spatial frequency domain. However, in the high spatial frequency domain, the setting angle error of the sensor causes a large deflection of the transfer function. Therefore, a combination method of the three-point method for roundness profile measurement and an integration method for the straightness profile measurement is proposed. The three-point method for roundness profile measurement is used to estimate low spatial frequency domain and the integration method for straightness profile measurement is used to estimate the high spatial frequency domain. Experimental results showed that the standard deviation of the combination method was smaller than that of the three-point method for most positions.</p>
