Avaliação da operação gargalo em uma linha de montagem de motores elétricos

Abstract

Well-structured production processes are fundamental to the good performance of a manufacturing company, and the identification and elimination of losses must be continuous.This premise is valid for all areas of the productive sector, including indirect ones, as is the case with test booths that are part of the production lines to ascertain quality conformity. The present work aims to evaluate the motor testing activity, an activity that is a bottleneck in the production process of electric induction motors. In order to carry out the work, the product mix was evaluated, and the main products produced in different work shifts were identified. The search for alternatives to reduce the time to test the engine was through chronoanalysis and action research, appling the utilizando technical knowledge and experience from the other areas involved (production, quality and metrology). The activities performed by the tester, alternatives for changing the power supply of the engines for a more modern model, installation of a double test station and carrying out the operation that requires more time one post before the test cabin were evaluated. A non-standardization of activities was identified, mainly between work shifts, where a standard procedure for the activity was proposed. It was also noticed that the alternative of starting the engine before the test was more effective in reducing the total time. Despite the need to create one more job in the production line, the alternative allowed to increase the mix of products produced in the line.
