Abstract
The present paper deals with the analysis of the manufacturing price of two pieces, produced in batch, by machining in a CNC machine with support of an integrated CAD / CAM system, aiming to establish the factors that most influence the final price of the product and the ways to optimize them. In order to perform the work, two random pieces of different materials that were modeled were selected and had their manufacturing process simulated through an integrated CAD / CAM software system. During the simulations it was possible to identify the most appropriate tools for the process as well as the best parameters and machining strategies aiming at the optimization of the costs related to the machining times. The simulations were based on the characteristics of the ROMI-600 machining center at the UFRN Manufacturing Laboratory, while the tooling and machining parameters were consulted in the SANDVIK catalog for rotary tools. Some costs (infrastructure, taxes, material price, personnel expenses, supplies) were fixed for the analysis of the price of the part, these costs have a significant part in the composition of the price of the product, the other part was related to the costs related to the machining times , these were optimized in order to achieve the lowest possible final price for the part, considering the constraints of the project. At the end of the work it was possible to obtain a final price of R$ 131.01 for part 1 and R$ 50.44 for part 2.
