Abstract
Significant technological advances in engineering have facilitated the production of parts for the medical industry, such as the Single Point Incremental Forming process (SPIF) for the conformation of customized parts in a reduced time. In this technique, the geometrical deviation of the surface and the system for its measurement are essential factors, given the difficulties of achieving close tolerances and obtaining accurate measurements quickly and cheaply. In this sense, the geometric conformity for medical applications of pure titanium cones formed by SPIF was evaluated in this work, in addition to comparing the measurement methodologies by 3D scanning with Kinect and by contact using a 3-coordinate measuring machine. From the comparison of shape deviations in relation to the theoretical cone and the surfaces measured by the two methods, the mean errors and mean standard deviations could be calculated, and 4D graphics showed the most deformed regions of the cones, which were the base and the top. The observed deviations were acceptable for many medical parts, while the use of Kinect proved to be feasible for fast, versatile, and highly economical verification of coarser tolerances on surfaces produced by SPIF.
