Diseño de una máquina con movimiento radial para corte de tubos con capacidad de hasta 10 pulgadas de diámetro

Abstract

This thesis focuses on the design of a machine with radial movement for cutting metal tubes up to 10 inches in diameter, aimed at strengthening the Ecuadorian metalworking industry through locally developed solutions. The relevance of this work lies in the growing need for companies and the industry to have precision equipment that reduces dependence on imported machinery, optimizes manufacturing processes, and enhances the competitiveness of workshops, small enterprises, and medium-sized industries. This research is positioned within the field of mechanical design and industrial machinery development, implementing principles of plasma cutting and fatigue failure analysis. The methodology is structured in several stages: a literature review, a comparative analysis of different cutting technologies, conceptual design, and computer-aided design (CAD). The calculation reports allow for evaluating bending stresses and determining the required safety factors on the shafts, ensuring that mechanical components do not fail under real operational loads, even when accounting for variations, unforeseen conditions, or fatigue.
