EN In industrial practice it is often necessary to obtain information regarding the geometrical characteristics of machine elements whose documentation does not exist or is unavailable. One way to obtain such information is by applying reverse engineering methods. This paper presents the process of digitization on a numerically controlled coordinate measuring machine CMM. An important problem is performing a correct numerical analysis of points obtained as a result of scanning of profiles having small radii of curvature, to be used for drawing parametric curves. Interpolation methods are necessary to obtain correct information about geometrical characteristics of machine parts.
