    Desarrollo de un plan de mantenimiento en el subproceso de molienda en La Industria Harinera S. A.
    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2020-09) Chiguano Allauca, Wilmer Wladimir; López Velástegui, Jorge Enrique
    The purpose of this technical project was to introduce the philosophy of TPM (Total Productive Maintenance) in the company La Industria Harinera SA, for which, 11 of the 12 necessary steps were carried out that are established by the JIMP (Japanese Institute of Plant Maintenance ) in the milling sub-process, which is the most critical of the whole flour-making process. This project established all the necessary parameters for the functional implementation of the philosophy, which are presented in a master plan for the 5 S, autonomous maintenance, planned maintenance, predictive maintenance and quality maintenance. This allowed them to be applied in the other sub-processes that the company owns, in the future if senior management so has it. The activities proposed for the planned maintenance in the B1 grinding bench were proposed based on the calculation of the maintenance indicators MTBF (Mean Time Between Failures) and MTTR (Mean Time To Repairs), these provided important data to perform the OEE calculation. (Global Effectiveness of Equipment) and thus allowed to make maintenance decisions that improve the performance of the equipment and the activities proposed for predictive maintenance, was based on recognizing with the TPM group the best predictive method that fits the parameters of the machine to be carried out maintenance. In each of the planned maintenance processes, standardization and audits were imposed to control and be able to carry out the continuous improvement method in a more efficient way.

    Elaboración de un plan de mantenimiento basado en el mantenimiento productivo total (TPM) para la maquinaria de recuperación de turbinas del CIRT EN LA Empresa CELEC EP –HIDROAGOYÁN
    (Universidad Técnica de Ambato, Facultad de Ingeniería Civil y Mecánica. Carrera de Ingeniería Mecánico, 2017) Lozada Cepeda, José Antonio; Castro Miniguano, Christian Byron
    The purpose of this project is to make a master plan in order to develop TPM (Total Productive Maintenance) philosophy for the Vertical Turning Lathe of the Turbine Research and Recovery Establishment CIRT. This project develops five of the twelve steps established by JIPM (Japan Institute of Plant Maintenance) for the TPM implementation. This project also provides the necessary documentation for: 5S and autonomous maintenance application. Also, some safety health and environment suggestions are provided. PM (preventive maintenance) activities are chosen based on RCM (Reliability Centered Maintenance) techniques like: CA (Critical Analysis) and FMEA (Failure Mode and Effect Analysis). Also, several predictive maintenance activities are established following ISO 3655, 1986. All these activities including automotive maintenance ones are organized and scheduled. Finally OEE (Overall Equipment Effectiveness) rate is applied to a broaching process to the vertical turning lathe in order to identify the principal losses on the machine.
