    (Universidad Técnica de Ambato. Facultad de Ingeniería Civil y Mecánica, Carrera de Ingeniería Mecánica, 2022-08) Navarrete López, Bryan Javier; Guamanquispe Toasa, Jorge Patricio
    In the MAVESA INDOAMÉRICA agency, after having examined its current state, it was found that the list of tools and equipment was obsolete due to the recent modernization of these, thus generating certain errors in the handling of information on a daily basis and without having an updated maintenance plan. This evidenced the need for a technical project focused on maintenance. In this project, information on tools and equipment was collected, observing their current state and an updated inventory was generated, then codified technical data sheets and a maintenance statistic were elaborated by calculating times with information for the period September 2020 - August 2021, which allowed elaborating and interpreting the bathtub curve. Following the methodology of the NTP 679, the AMFE matrix was developed, allowing to specify the representative tool systems and equipment of the company, detailing their failure modes, root cause and effect, and then giving them a weighting to obtain the most critical ones, followed by the codified maintenance ranges. As a result, an annual preventive maintenance plan for tools and equipment was developed, organized with activities, frequency and duration for a whole year, and to complement it, a support program was implemented with the help of free software.

    Prevention is the only way to avoid serious future problems, this applied to any work area or even in life itself, in this way in the industrial sector the useful life of machines and equipment could be improved and extended, that is the importance of using a preventive maintenance plan. For its realization, it began with the development of the technical sheets and a study of the current situation of the maintenance carried out on each machine, these data were represented in a statistic and interpreted by means of the curve of the bathtub, then the identification of systems, components and functions of the same for the subsequent analysis of the main causes that cause failures. Next, a mode analysis of failures and FMEA effects was carried out through a matrix where the functional failure, failure mode, effect, root cause and a recommendation of two possible failures were detailed for each component, and the components with greater NPR, in this way the preventive measures of the same were prioritized, this was based on the Technical Note of Prevention NTP 679. Finally, a technological software was obtained as a final product with the annual preventive maintenance plan for the transport system by buckets, which contains the ranges of maintenance, generation of monthly reports, resume, and curve of the bathtub for the control of failure stages.

    The purpose of this technical project is to introduce the philosophy of TPM (Total Productive Maintenance), to carry out a maintenance plan with a one-year projection of the most critical machines of the company PLANHOFA CA, based on the application of the 5S, global effectiveness equipment (EGE), autonomous and planned maintenance. The project establishes the necessary formats for maintenance management such as: technical sheets, work order, red card for unnecessary elements, machine inspection sheet and external services. The activities proposed for the maintenance of the most critical machines are proposed based on the manuals, historical data of each equipment, quantitative criticality analysis and the modal analysis of failures and effects, better known as AMFE, with which the critical components are obtained. On the other hand, a machine is chosen for the calculation and implementation of the overall effectiveness of the equipment, for which an Excel format is made to facilitate the calculations and interpretations thereof. The same that will serve as a pilot test to be applied to the rest of the machines if required by senior management. All maintenance activities are organized and classified in the range, to later translate them into the annual maintenance plan. Therefore, the applied maintenance philosophy can avoid as many unplanned failures as possible and thus be able to provide excellent quality products to the national and international market.
