Item Plano de manutenção preventiva para uma parafusadeira em uma empresa do Pólo Industrial de Manaus(2020-10-01) Gomes, Felipe Menezes; Costa, José Francisco de Caldas; http://lattes.cnpq.br/5703032306296974; Costa, José Francisco de Caldas; http://lattes.cnpq.br/5703032306296974; Castro, Cristovão Américo Ferreira de; http://lattes.cnpq.br/4930257608461492; Chagas, Sidney Assis; http://lattes.cnpq.br/1705258854443084In the company of industrial pole in Manaus, Beta Ltda (fictitious name) made a study on the failure modes in a screwdriver in the electronic sector in order to diagnose problems related to corrective maintenance and maintenance time. And the objective is to compare a corrective maintenance program (current) with the preventive maintenance plan (ideal). The methodology used was divided into four stages, such as what are the study or case factors, with probability of failure, development of a cycle counter device and finally, or a preventive maintenance plan. As the results were given frequency of failure and the most recurrent failure modes, as well as a probability of failure was identified, the ideal period for preventive maintenance, or the number of pre-failure operation cycles and the preventive maintenance plan used previous results. As final considerations elucidated that were verified without correspondence with the results found for probability of real failure, the cycle counter device is accused of approximately 20º. the day of each month is necessary to carry out preventive maintenance and, finally, the implementation of the preventive maintenance model saves more than 300 min / month of maintenance time.Item Redução de perdas com manutenção corretiva utilizando um sistema de monitoramento em uma linha de usinagem(2021-10-04) Oliveira, Luciana Marta do Nascimento de; Arruda, Gutembergue da Silva; http://lattes.cnpq.br/8833717823163756; Arruda, Gutembergue da Silva; http://lattes.cnpq.br/8833717823163756; Rodrigues Filho, João Nery; http://lattes.cnpq.br/3860803328978892; Castro, Cristovão Américo Ferreira de; http://lattes.cnpq.br/4930257608461492Considering that autonomous maintenance is based on the ability of the manual labor to carry out small and simple maintenance techniques, which can range from cleaning and lubrication to even the retightening and regulation of machines, these types of routines generate a critical sensor in the operators so they are able to look after and detect future problems. In view of the effectiveness of these practices, the WCM (World Class Manufacturing) methodology turned them into one of its 10 technical pillars, for the development of these activities within the methodology it is necessary to follow the tools: CIL-R, Dirt source map, AM cards, Area classification, Golden zone, SOP, 5S, ECRS. The entire process of implementing autonomous maintenance on a machine begins with the reestablishment of its basic conditions, so it is essential to clean and remove useless objects, in order to identify and treat such anomalies. The following steps will only be effective if the first one is done in a thorough and precise way, as they are based on the results found in the previous one. The research presented in this work is related to the implementation of the autonomous maintenance pillar according to the WCM methodology in a packaging machine, expressing in the field all the tools and possibilities for improvement in the processes achieved through the WCM practices.Item Redução de perdas com manutenção corretiva utilizando um sistemas de monitoramento em uma linha de usinagem(2021-08-20) Silva Júnior, Emerson Nascimento da; Plácido, Marisol Elias Barros; http://lattes.cnpq.br/1902514007423220; Plácido, Marisol Elias Barros; http://lattes.cnpq.br/1902514007423220; Costa, José Francisco de Caldas; http://lattes.cnpq.br/5703032306296974; Queiroga, Alberto Luiz Fernandes; http://lattes.cnpq.br/9632649964503729Currently, with the progress of automation, it is possible to capture valuable data and information from an automated process in real time, making the interpretation and use of this data the differential to take decision. With this, automation facilitates the capture of information to be passed on to maintenance managers correctly and at the correct time, maintaining the reliability of the information and being able to anticipate problems. With this in mind, this work aims to analyze the maintenance problem in a two-wheeled pole industry and propose a solution through automation. For this, the methodology was divided in four parts: analysis of the current situation, analysis of causes, analysis of proposed solutions and implementation. In the analysis of the current situation, the maintenance performance indicators were quantified. In the analysis of the causes, the root causes of the problems found were investigated. And then, the specific goals and objectives were quantified. Finally, the study of solutions and implementation of improvements in the machining process was carried out. Through this work, it was possible to visualize the losses of a maintenance process, and thereby obtain several gains. Among them, the reduction of unscheduled equipment downtime, automation of the process monitoring and a 48% reduction in MTTR at the machining plant.
