Influence of installation error on roundness error measurement [PDF]
IOP Conference Series: Materials Science and Engineering, 2019 Abstract The installation tilt causes the actual measured circular contour to be an elliptical contour [1], and the installation eccentricity causes the sampled points uneven [2], which can both affect the measurement accuracy of the roundness error [3, 4].
