Since then, the evolution in the manufacture of tools and the development of special machines has made it possible to manufacture molds and dies with greater precision and heterogeneity. As far as the cutting tool is concerned, the ones that allow higher cutting speeds, longer service lives, or that replace two or more tools are more interesting. Faced with the difficulties of not having a national certified supplier, and the high import costs, the need arose to manufacture a batch of cubic metal molds in accordance with the requirements of the NBR 9831: 2020 standard. The present work aims to demonstrate the main parameters used in the machining of the steel cubic mold. Within this context, the work is divided into some stages, such as, specification of materials, manufacture of components, geometric modeling, and analysis of results. AISI 304 austenitic stainless steel is used to make the cubic mold, due to its high resistance to corrosion. The manufacture of components is carried out through various mechanical manufacturing processes, with milling as the main one, a process widely used on flat surfaces. The modeling uses computer-aided engineering design software, CAD (computer-aided design). The results proved to be quite satisfactory, as the final dimensions met the technical requirements of the standard. At the end, it is concluded that the molds manufactured are able to produce cement slurry cubes for compressive strength tests.Usinagem, moldes e matrizes, fresamento, Aço inoxidávelMachining, molds and dies, milling, Stainless steelbachelorThesis
