Ítem Monitoring of machining in the cloud as a cost management service and follow of cutting parameters: Environment developed with IoT tools(IGI Global, 2019-01-01) Giraldo-Castrillon F.-A.; Páramo-Bermúdez G.-J.; Muñoz-Betancur J.-M.; Giraldo-Castrillon F.-A.; Páramo-Bermúdez G.-J.; Muñoz-Betancur J.-M.; Universidad EAFIT. Departamento de Ingeniería de Producción; Grupo en Tecnologías para la ProducciónThe present work developed an environment in the cloud with IoT tools for the intelligent monitoring of cutting processes in a three-axis CNC machine. To achieve it, a group of sensors incorporated into the machine are connected to a data acquisition card in charge of sending the measurements delivered by the sensors to the IoT environment in the cloud. The data received was processed in real-time, and at the end of the machining, an automatic report was generated that includes: the cost of the operation, total process time, average energy consumption in watts, and positions of the X, Y, Z axes in function of time. The findings of this study bypass production managers from developing a processes sheet, reducing fabrication time, and increasing productivity. The architecture of the system was put to the test raising two case studies, which demonstrate the relevance and the significant impact of the platform in the new era of digital manufacturing. © 2019, IGI Global.Ítem Statistical analysis of the parameters in SPIF/DPIF in the thickness reduction in an experimental geometry(Inderscience Publishers, 2019-01-01) Giraldo-Castrillon F.-A.; Giraldo-Castrillon Y.-M.; Páramo-Bermúdez G.-J.; Giraldo-Castrillon F.-A.; Giraldo-Castrillon Y.-M.; Páramo-Bermúdez G.-J.; Universidad EAFIT. Departamento de Ingeniería de Producción; Grupo en Tecnologías para la ProducciónThe objective of the present study was to determine the thickness reduction during the incremental deformation process with two techniques: SPIF/DPIF. A geometric structure was built using software computer-aided design (CAD) and the paths simulated in software computer-aided manufacturing (CAM). Experimental design of a full factorial type was made 23, for each technique, eight simulations, and three replicas. The variables studied in each experiment were the wall angle, the depth increase and the diameter of the tool. The three parameters are associated with the incremental deformation, although the angle was the most influential and the interaction between them in both techniques was significant. There was no difference in the comparative analysis between the different points in which the reduction of the thickness measured, just as neither one technique showed to be superior to the other. The angle of 68°, the depth of 1.0707 mm and the diameter of 9.3737 mm produced the least deformation with the SPIF technique and the angle of 60°, the depth of 1.2 mm and the diameter of 8 mm produced the least deformation with DPIF. © 2019 Inderscience Enterprises Ltd.
