2. Aspects on the optimization of die-sinking EDM of tungsten carbide-cobalt
At present, due to their properties, the tungsten carbide-cobalt (WC-Co) composite materials are in huge demand by industry to manufacture special tools, dies/molds and components under erosion. The powder metallurgy is the usual process applied to obtain WC-Co products, but in some cases this process is unable to produce tools of very complex shapes and hig

3. Estudo dos esforços de corte no processo HSM aplicado à abertura de cavidades / Study of the cutting forces in HSM process applied to pocket milling
The manufacturing of a great number of components in the industry depends on molds and dies used in processes like forging, powder metallurgy, deep drawing, casting and plastic injection. One of the main operations for manufacturing of these parts corresponds to the opening of the initial pocket, from which more complex geometries are machined in order to ob

4. Internal adaptation of cast titanium crowns
As the adaptation of titanium crowns obtained by Rematitan Plus investment, specific for titanium, is not recognized to be suitable, this study evaluated the effect of the concentration of the specific liquid and the temperature of the mold of investments on the internal misfit of crowns cast on commercially pure titanium. Individual dies of epoxy resin were

5. Influence of HSM milling cutting parameters on tribological performance of hardened AISI H13 steel. / Influência dos parâmetros de corte do fresamento HSM sobre o desempenho tribológico do aço AISI H13 endurecido.
Since 90, the HSM milling process to manufacture dies and molds has been applied and, more specifically, in finishing operation those components. In according to LFS/USP survey, among São Paulo region dies and molds users, the dies and molds life dispersion has been confirmed. This dispersion can be related with machining effects on tribological performance

8. Uma contribuição ao estudo do fresamento de aço endurecido com fresa de topo esferico
The milling of molds and dies cavities carried out on hardened steel using ball end mill presents limitations in terms of cavity depth, metal removal rates and tool life. Some milling operations on deep cavities are not possible due to the require of long tool overhang, what generates vibrations and, consequently, resulted in poor surface roughness and short
