Redução do risco de uma operação com máquinas rotativas utilizando engenharia reversa e impressão 3D

Abstract

Additive manufacturing and reverse engineering are important topics of the fourth industrial revolution and show themselves as the solution for a diversity of situations. This work presents an application using these two technologies for the project and fabrication of nutrunners protections used at the automotive industry, in Curitiba, Parana, Brazil. The PDCA methodology – Plan – Do – Check – Act – was the base for the development, done in this part of the project until the “Planning” step. The process was detailed, step by step. The root causes were identified, and reverse engineering in addition to 3D printing were identified as the best solution. The two technologies were shown as ideal alternatives, attacking all the root causes simultaneously. A standard tool scanning, modeling and printing method was proposed. The part was printed, tested and validated at the production line, with help of the Occupational Health & Safety department. The risk was reduced as expected.
