Propuesta de mejoramiento del proceso productivo del área de mecanizado en la Empresa López Torres Industrial S.A. aplicando las herramientas de Lean Manufacturing

Abstract

This degree research has as objective to develop a proposal to improve the production process of the machining area the company López Torres Industrial S.A. applying Lean Manufacturing tools and one of these was Value Stream Mapping (VSM), where the flow of products and information of the production process was observed with the help of the process diagram, in addition the waste of the production process was identified, first the initial VSM was performed in which waste was found such as, overproduction, on processing, waits and defects; these wastes were analyzed and the future VSM was proposed, where the improvement proposals were established, he state of order and cleanliness of the company was also evaluated through the 5’s methodology, a fundamental tool of the Lean philosophy. The results obtained from the initial VSM were 90.05 min at the time of the process, a takt time of 90.05 min/u and 145.4 min in the lead time these data these data pertain to the pump axis, in the housing pipe the process time is 41.3 min, takt time of 41.3 min/u and the lead time of 79 min; in the future VSM the results were on the pump shaft 9 min less in process time, 9 min/u less in takt time and 18.6 min less in lead time; compared to the accommodation pipe were 7.8 minutes the reduced in lead time. The second tool used was the 5'S, in the initial audit it found an unsatisfactory percentage of 33.33% compliance, by implementing the methodology its percentage increased to 84.45% which is satisfactory. In conclusion, Lean Manufacturing's tools helped to identify waste and propose improvements in the production process of the machining area.
