A new single probe scanning method for on-machine measurement of roundness error

This paper proposes a new measurement method based on a single probe scanning to measure the roundness error of the artifact. The presented method simplifies the mathematical processing. There is no need for complex forward and inverse Fourier transforms. The probe is installed on a micro-stage platform, and a voice coil motor drives the micro-stage platform. In this paper, a precise mathematical model of the proposed measurement method is carried out and a detailed introduction process. Computer simulation analysis proves the feasibility and repeatability of the method. The related factors affecting the accuracy of the measurement system are analyzed, and the corresponding suppression methods are proposed. Finally, a comparative experiment verifies that this method dramatically improves the measurement accuracy compared to direct measurement.
