Variability Analysis of Multiple Geometry Data for Accuracy Assurance of Reverse Modeling of Precision Parts

Abstract

In reverse engineering of precision mechanical parts, ensuring the quality of measurement data is crucial, as it forms the basis for accurate modeling. To validate the accuracy of measurements, it is necessary to repeatedly measure the same shape and assess the variability. In this study, a coordinate measuring machine (CMM) was used to perform multiple measurements of extrusion-shaped samples at various locations. Detailed analysis of the variability in the contour data obtained provided valuable insights for improving the accuracy of reverse modeling.
