Should cost aplicado na fabricação de parafusos sextavados M10, pelos processos de metalurgia do pó, conformação mecânica e usinagem CNC

Abstract

In an increasingly globalized market, it is necessary to apply methodologies that make the means of manufacturing as competitive as possible. In view of this, the cost should emerge as an excellent tool for analysis and cost management, even for common everyday parts of mechanical engineering, such as hex screws. Using full-thread M10 hexagon screws, the work will address the assembly of 3 production lines, powered by powder metallurgy, mechanical forming and CNC machining, respectively, in order to determine the direct and indirect costs of the processes, so that it is possible to determine the value of each piece produced. Costs were estimated by market research and estimates by comparing values obtained in other works and similar products. Finally, it was resisted that the production line based on mechanical forming was the most economically viable, in sequence, it was established that the production line based on powder metallurgy was the second cheapest and, finally, CNC machining proved to be the manufacturing method that requires higher costs and lower productivity, being indicated for specific batches or large screws. The work still aims to bring the advantages and preservation of each process.
