Item Aplicação da ferramenta FMEA na máquina de sangrar freio numa indústria automobilística de duas rodas(2023-08-01) Iwata, Bruno Hiroshi Nakamura; Maciel, Paulo Fernando Figueiredo; http://lattes.cnpq.br/0169675639305530; Maciel, Paulo Fernando Figueiredo; http://lattes.cnpq.br/0169675639305530; Pinto, Camila da Costa; http://lattes.cnpq.br/5909706356694272; Queiroga, Alberto Luiz Fernandes; http://lattes.cnpq.br/9632649964503729Given the growth of competitiveness in the industrial scenario, the existence of maintenance management is essential for increasing asset reliability and availability. Thus, ReliabilityCentered Maintenance (RCM) suggests a structured methodology for conducting maintenance management with a focus on preventive actions. Therefore, this study proposes the use of the Failure Mode and Effect Analysis (FMEA) tool in a brake bleeding machine of a two-wheeler automotive industry. The main objective of this work is to reduce failure time and increase the Mean Time Between Failures (MTBF) of the respective machine. To determine the machinery to be applied in the tool, a survey was conducted on four machines that had the highest records of unplanned maintenance in the year 2021, and thus, the one with the greatest impact was chosen. For this process, the FMEA table was filled out with the main components of the machine, indicating their function, the main failure modes and effects, as well as the classification of the priority index for each item, through risk assessment. Subsequently, the existing preventive maintenance plan was reviewed and reformulated based on the analysis. Additionally, the necessary materials were acquired and scheduled replacements were carried out according to the established work schedule. The implementation of the methodology contributed to the optimization of maintenance plans, as well as a 70.4% reduction in corrective failure time compared to the initial analyzed period.Item A importância da inspeção de defeitos de soldagem por fusão através de ensaios não destrutivos e da metodologia PoD(2017-06-28) Garcia, Luiz Eduardo Caldas; Monteiro, Alberto de Castro; http://lattes.cnpq.br/8300386519703896; Monteiro, Alberto de Castro; http://lattes.cnpq.br/8300386519703896; Nascimento, Andrea Regina Leite do; http://lattes.cnpq.br/2993012897803928This work came initially from the need to make a study on the reliability of non destructive tests in the application of detection of welding defects. We know that inspections, in most cases, are performed manually, and the human factor, however well-trained and knowledgeable for make this activity, reduces the reliability of inspection visual results. Therefore, it is necessary to apply auxiliary statistical tools in the detection of defects, to guarantee the reliability of the inspection. First, a review of the literature on welding and applications was made. The following was a survey of the main defects inherent in fusion welding processes. The study allowed us to conclude that the use of PoD curves in the tests is a simple methodology, which provides a greater reliability to the test because it allows greater certainty that an identified defect is actually present in the inspected part, since the curve Is generated according to the dimensions of a defect.Item Estudo de caso: a implantação do planejamento e controle da manutenção em uma indústria do polo de duas rodas de Manaus(2021-05-21) Sena, Thamires Lucena de; Castro, Cristovão Américo Ferreira de; http://lattes.cnpq.br/4930257608461492; Castro, Cristovão Américo Ferreira de; http://lattes.cnpq.br/4930257608461492; Lima, Placido Ferreira; http://lattes.cnpq.br/0865439005714077; Gama, Marcelo Martins da; http://lattes.cnpq.br/2955108730907462Taking into account the demands and competitiveness of the market to be able to increase efficiency and reduce costs, it is necessary to apply techniques in the management of sectors, especially in the maintenance sector. This work intends to accompany the Implementation of the Maintenance Planning and Control (PCM) functions in a two-wheel hub company in the industrial district. This implementation proposes to approach the concepts of PCM, portraying the system used until then by the sector in order to suggest improvements based on the management of the PCM. The methodology used will then be divided into four stages. The first is based on assessing which maintenance methods are appropriate for the assets present in the company. In the second phase, the specific functions of the PCM are structured, with the registration and classification of assets being carried out in agreement with the sectors of production and quality. In the third stage, maintenance schedules are developed and maintenance sheets are created, in the last stage, maintenance indicators are implemented. The final objective is to obtain a maintenance control structure able to guarantee the availability and reliability of the assets.
