Abstract

This article has as its theme the study of the impacts on productivity resulting from the technological updating of processes, analyzing the results of the installation of new machines in a manufacturing cell of fixed joints used in the transmission of torque from the engine to the front wheels of automobiles. This study is justified because technological innovation has a fundamental role in the search for improvements in processes and products and, consequently, in the increase of production rates in industries, so that more is produced and with less costs. The objective is to carry out a critical study of the replacement of outdated machines, with new equipment in a manufacturing cell of an automobile company, as well as to describe the impacts resulting from this substitution in the production process. Therefore, as part of the methodology, the cell's OEE was used as a parameter to extract the data and analyze the productive bottleneck. Set-up times were also measured and maintenance stops were analyzed to assess machine availability. The cycle times were timed in order to observe the performance of the cell and also, data collected on the quality of the equipment in the months under study. After collecting the data for study and analyzing the results found, the result was that the substitution generated a significant impact, mainly in the availability indicators with a 10% decrease in inherent process stops and a 39% improvement in quality. As final considerations, it was also noted the need to replace another machine to further enhance the impacts of the cell's technological innovation.
