    Comparación del comportamiento de la trayectoria de los deslizamientos entre modelos geométricos y empíricos para el mapeo de zonificación de amenaza por movimientos en masa de la vía Bolombolo – Amagá sector Sinifaná Km 57

    Mass landslides are events that can cause the destruction of homes, loss of human life and affect traffic on a road. The study was carried out on the Bolombolo – Amaga road in the Sinifana sector at kilometer 57, leaving Southwest Antioquia cut off for 6 months. These events can reach long routes with high speeds that cause effects of this type. Several studies analyze displacement propagation using an empirical and geometric approach such as Flow R and Model T. These models have a great advantage since they are freely accessible and the input parameters are easy to obtain. A parametric study was carried out to select the variables that best fit each model, because the objective of the following project is to compare the models found for the determination of hazard zoning and behaviors of the trajectory generated by mass movement. The results obtained are validated by comparing them with the corresponding photo-interpretation carried out in the study area.

    Statistical analysis of the main incremental forming-SPIF process parameters that contribute to the change the roughness in an experimental geometry

    Over time the process of incremental deformation of sheet metal without matrix in its variant (SPIF), has been developed in different countries with the aim of meeting the needs of flexible production with no investment in tooling and low production costs. As in any manufacturing process is important to obtain a surface quality of the part that meets customer needs, this variable is evaluated by the average roughness (Ra). For this reason the purpose of this study is to investigate the influence of the variation of three process parameters and determine which of them contributes in greater proportion to the change in the average roughness (Ra) measured parallel and perpendicular to the path followed by the tool. Besides this, it wants to validate the impact that has the spindle speed in the analyzed variable and the orange peel defect. To this end, a full multifactorial design of experiments with three factors and two levels () and three replicates were performed, in order to obtain greater reliability in the model. Subsequently, an analysis of variance is executed and the results are formalized, finding which parameters influence more than others in changing roughness and how the orange peel defect depends on the spindle speed. Additionally, the results are compared with the authors cited. The aspects developed in this study highlight the importance of improving quality variables in any field of sheet metal processing in the international industrial environment.
