Abstract(s)
Esta dissertação foi desenvolvida na empresa ABER Embraiagens e Comandos Hidráulicos, na Maia, e teve como tema a realização de um plano estratégico para a manutenção. A metodologia escolhida foi o Total Productive Maintenance (TPM) e as células escolhidas para a implementação foram os Tornos CNC e Centros de maquinagem CNC. O TPM compreende um conjunto de atividades de manutenção, que advêm da manutenção preventiva, e focaliza-se na eliminação de perdas de eficiência. Analisaram-se e eliminaram-se os principais problemas dos equipamentos contidos nas células. Através da análise dos manuais de manutenção e do know-how interno, foram criados procedimentos de manutenção autónoma e planos de manutenção preventiva a serem executados com determinada periodicidade. No final do estudo, os resultados foram muitos positivos graças às ações corretivas, preventivas e de melhoria efetuadas. Verificou-se uma diminuição no tempo de paragem por avaria de 23% e 38% para tornos e centros, respetivamente, que provocou um aumento evidente na disponibilidade das máquinas.
This project was developed at ABER Embraiagens e Comandos Hidráulicos, in Maia, being the main focus the Implementation of a strategic plan for maintenance. The philosophy chosen was Total Productive Maintenance (TPM) and the cells chosen for implementation were CNC Lathes and CNC machining centers. The TPM uses some maintenance activities, which come from preventive maintenance, and focuses on eliminating efficiency losses. The main problems of the cell equipment were analyzed and eliminated. Through the analysis of maintenance manuals and internal know-how, autonomous maintenance procedures and preventive maintenance plans have been created to be executed following a given timeframe. At the end of the study, the results were very positive thanks to the corrective, preventive and improvement actions carried out. There was a decrease in breakdowns due to failure by 23% and 38% for CNC lathes and CNC machining centers, respectively, which resulted in an evident increase in machine availability.
