Measurement of Geometry of Small Axisymmetric Sheet Metal Component after Forming

<p><span lang="EN-GB">Axisymmetric small components shape has many 3 dimensional curves, diagonals and “hidden” areas that are subject to changes during production and these changes are necessary to detect. Measurement with required accuracy may be challenging because of limitations connected with one measurement method. Component geometry and deformation is necessary to observe for several reasons. Modelling the forming process requires the feedback from production of components with real geometry, deformations and even changes in sheet metal thickness. These values can change during production process because of changes in tool condition, material properties, coating and sheet metal thickness. Changes in part geometry and deformations affects the final product properties that is important to study. The purpose of the study is to improve the product reliability and control the geometry of the components during the manufacturing process. In present study different components are measured with different methods and compared to each other. Metallographic cross-sectioning method is developed to get reliable results of sheet thickness and hidden areas geometry of the component assembly. Results show that some 3D scanning methods can provide accurate measurements and can be used as reasonable labour-intensive method for the most of the measurements. However combined measurements are used to get all necessary data from the component. Metallographic cross-section method is necessary especially for assembly measurement.</span></p><p>DOI: <a href="http://dx.doi.org/10.5755/j01.ms.21.3.7384">http://dx.doi.org/10.5755/j01.ms.21.3.7384</a></p>
