Estudo de modelagem e dos parâmetros de usinagem CNC aplicados na carcaça do redutor de engrenagens do veículo tipo baja da equipe Procobaja da UTFPR-CP

Abstract

The present study aims to optimize the modeling and define the machining parameters of the housing of a gearbox intended for a Baja vehicle. The motivation for this research lies in the need to improve the prototype's performance, given that the standardized 10 HP engines used in the competition have low power and torque. Therefore, the development of efficient components capable of minimizing losses and reducing overall mass becomes essential. The main objective is to optimize the gearbox housing geometry, using as a reference the current model developed by the Procobaja team from UTFPR-CP, with the goal of achieving at least a 40% reduction in mass without compromising structural strength. The proposed methodology includes the collection of data regarding failures and improvement opportunities in the existing model, optimization of the 3D CAD modeling, execution of structural simulations, and definition of CNC machining parameters such as tooling selection, cutting speed, feed rate, and depth of cut. The expected results include obtaining a lighter housing without compromising rigidity, aiming to improve assembly and maintenance efficiency, as well as dimensional accuracy, surface finish, and overall functionality. By the end of the project, the optimized component is expected to be machined, allowing for an experimental comparison with the previous model. Preliminary results have shown a significant mass reduction without compromising the component's strength.
