Presentation of a three-dimensional metrology software

This paper presents a three-dimensional metrology software,named « GFDSoft » Geometrical Form Defect Software, developed by MOULAI-KHATIR. GFDSoft implements the least squares adjustment criterion (which is the most commonly used criterion on Coordinate Measuring Machine “CMM” software) and the minimum zone (Chebyshev) criterion. We will present in this work, the mathematical modeling by the criterion of least squares adjustment for the case of the flatness. We will also present applications to measure the flatness defect on industrial parts.Then we will validate our software, comparing our results to results of works of the scientific literature, as well as by performing a comparison of our software with others three-dimensional metrology software's
