Description
Summary:The present work is classified within the framework of the final thesis in mechanical engineering at Högskolan i Skövde. The aim is to carry out a literature review and a subsequent analysis of how workpiece clamping is performed in the thin-walled machining industry. Specifically, in the boring operation so that the workpiece is correctly clamped and does not suffer greater form errors than desired.In order to get to know the work environment, some preliminary concepts are presented to get used to it. Then, at the core of the work, an exhibition of the conceptual alternatives for generating the clamping of the thin-walled workpiece is presented.When concepts have been gathered, development of CAD models of the two clamping systems observed in the literature review that are the most used in the industry is performed, the 3 jaw-chuck, and the 6 jaw-chuck models.At the last stage, to proceed to the comparison of the two models, virtual validation of the two models is performed through FEM analysis. Through FEM it is observed that there is a clear between using more clamping points and contact area and fewer deformations in the workpiece. Lastly, the model that presents better results in the analysed environment is chosen, which is the 6 jaw-chuck system.
