Ítem Desarrollo de una herramienta inyectora de fertilizante soluble para el cultivo del banano(Universidad EAFIT, 2010) Colorado Herrera, Jorge Mario; Acevedo, MauricioÍtem Manufacturing process planning under a product lifecycle management approach(2010-12-08) Mejía Gutiérrez, Ricardo; Ruíz Arenas, Santiago; Universidad EAFIT. Departamento de Ingeniería de Diseño; Ricardo Mejia (rmejiag@eafit.edu.co); Santiago Ruiz (s.ruizarenas@tudelft.nl); Ingeniería de Diseño - GRIDThe Product Lifecycle Management (PLM) concept may be used to align Knowledge Management with Manufacturing Process Planning -- This paper presents an ongoing research in the use of a PLM tool to support the process planning of machining processes, including High Speed Machining (HSM) -- The project integrates a novel and competitive PLM solution for emerging markets, such as developing countries or Small and Medium Enterprises (SME) -- A module for managing CAD/CAM information under a PLM approach is proposed and its implementation is described to clarify the Manufacturing Process Planning under a PLM environment -- The paper reports the experience using the tool and discusses opportunities and pitfalls in its useÍtem Modelación paramétrica y manufactura de mezcladores para extrusión de termoplásticos utilizando sistemas CAD-CAM(Universidad EAFIT, 2008) Marín Urrego, Juan Sebastián; Romero Escobar, Luís Felipe; Rodríguez Arroyave, Carlos ArturoÍtem Modelo de integración de la Gestión de Procesos de Negocio (BPM) y la Gestión del Ciclo de Vida del Producto (PLM) en el diseño de pequeños aerogeneradores (SWT)(Universidad EAFIT, 2017) Palacio Laverde, Carlos Eduardo; Mejía Gutiérrez, RicardoThe project presents the integration of methodologies such as Business Process Management (BPM) and Product Life Cycle Management (PLM) to propose a model that allows standardizing the design of small wind turbines -- To do this, a relationship is established between the process management methodologies applying the management chains where the process flow design and the product life cycle management are shown, showing the life cycle and flow design in addition to the application of CAD, CAE and CAM tools -- To achieve this objective, ARIS Express software for the development of process flows and ARAS Innovator for the development of life cycles and workflows is applied -- The Aris Express software application shows the design of two processes, the first the study of the place and the second, the design of the small wind turbine -- For the construction of the model, design methodologies published in the journal and in some books where the design of small wind turbines are presented, or the analysis of these, but a model is not proposed where the management of the processes is integrated in a collaborative way and the management of the life cycle in a way that allows to establish a standardization in the design process of small wind turbines -- The construction of the model was applied in a case study that shows the integration in a collaborative way of the Process Management and the Product Life Cycle Management and the application of the engineering tools from small wind turbines developmentÍtem Product conceptualization through a 3D natural interface considering in real-time spatial and ergonomic restrictions(Universidad EAFIT, 2014) Arroyave Tobón, Santiago; Osorio Gómez, Gilberto; Osorio Gómez, GilbertoCurrently, the conceptualization of products whose shape and configuration depends on the context is a highly time-consuming process since it has to be achieved asynchronously between the real environment of the product’s usage and the design office -- In general, the designer manually maps the context in order to create a 3D model of it and then to start the product design process -- The literature presents some proposals to digitalize the context without the need of a manual mapping -- However, these approaches are mainly computer-centric tools where the designer is desk-bound and (s)he does not have a clear spatial perception since the interactions with the 3D models are usually based on 2D interfaces -- On this research we aimed to prove that conceptualization of context-dependent products directly over its real environment through gesture-based modeling tools, allows the designer to consider spatial and ergonomic restrictions that the context imposes to the product, through the real-time analysis of the interaction user-context -- In order to prove that, we developed a tool called Äir-Modeling, in which the designer is able to create virtual conceptual products quickly and efficiently, taking advantage of hand gestures meanwhile (s)he is interacting directly with the real scenario in an Augmented Reality (AR) environment -- Air-Modeling also allows a continuous evaluation of the user postures involved in the product usage and assembly in order to analyze ergonomic risks, and perform the necessary changes in the product shape or configuration from early stages of the design process -- A test was carried out to prove the effects of the use of the proposed tool in the design process in comparison with the traditional way through traditional CAD packages -- We found that the real context can be used as an information input in real-time during product conceptualization -- Beside this, we could notice that virtual parts creation is more efficient from a 3D input than a 2D interface such as a mouse or a keyboard -- This was reflected in the experiment carried out in which 21 users conceptualized a bookcase for a given context using both Air-Modeling and a commercial CAD tool -- It was obtained a reduction in the modeling time using our tool on 76% of the cases with a final average reduction of 44%. Finally, we concluded that 3D modeling in AR environments using the hands as interface and the context as an information input in realtime, allows the designer to conceptualize potential solutions in quick and efficient manner, exploiting as much as possible, inspirational instants -- On the other hand, modeling in a natural scale directly over the real scene prevents the designer to draw his/her attention on dimensional details but allows him/her to focus on the product itself and its relation with the environment -- Besides, developing 3D models in natural scale allows analyzing the interaction between the user, the context and the virtual model for determining ergonomic issues related with the product usage or assembly process -- We believe that this kind of technologies makes the development of customized products more efficient by adding spatial and ergonomic restrictions to the conceptualization process in real-time -- This facilitates the convergence to the design solution, possibly avoiding some iteration in the design processÍtem Sistema posicionador de clisés en lonas de PVC, para la impresión de cajas de cartón corrugado(Universidad EAFIT, 2010) Muriel Gil, Luisa Fernanda; Moreno Llano, Andrés; Gómez González, Mateo; Roldán Peláez, María Paola; Aristizábal Restrepo, Sergio
