Abstract(s)
O presente trabalho teve como objetivo a aplicação das ferramentas do Lean Manufacturing em um processo de fabricação de carcaças para motores elétricos. O foco do trabalho deu-se na redução de tempos de setup a partir do uso do Single Minute Exchange of Die e na atualização das ferramentas envolvidas no processo de fabricação para diminuição do tempo do processo geral. O trabalho desenvolve-se seguindo a metodologia DMAIC, onde é feito o mapeamento dos processos envolvidos, a medição de tempos das atividades, a análise das possíveis melhorias e modificações, a aplicação desses projetos elaborados e posteriormente o controle e a documentação do novo processo desenvolvido. Através da implementação destes novos métodos de produção obteve-se um ganho de capacidade da máquina em torno de 20%, reduzindo os turnos extras para compensar a produção e aumentando significativamente a capacidade da linha produtiva. Desta forma, restou evidenciada a relevância de um setup aprimorado e um bom gerenciamento de ferramental para maquinagem no tempo final de um produto.
The present work had the objective of employing the tools of Lean Manufacturing in the fabrication process of carcasses for electric motors. The focus of the study is on reducing setup times by the usage of SMED and by upgrading the tools involved in the manufacturing process to decrease overall process time. The work is developed while following the DMAIC methodology, in which the involved processes are mapped, the activities times are measured, the possible improvements and modifications are analyzed, the developed projects are applied, and finally both control and documentation of the new process are performed. By implementing these new production methods, the machine gains about 20% more in its capacity, reducing the extra shifts for compensating production and significantly increasing the efficiency of the production line. Hence, it is evidenced the relevance of an improved setup and of a good management of machining tooling on the total time of production.
