1. Modelo térmico para a solução de problemas inversos em transferência de calor com aplicação em um processo de usinagem por torneamento / Thermal model for the solution of inverse problems in heat conduction with application in machining process
Durante o torneamento a energia mecânica é convertida em calor através da deformação plástica do cavaco e do atrito entre a ferramenta e a peça. O calor conduzido na ferramenta de corte resulta em altas temperaturas na interface de contato. A partir do conhecimento destas temperaturas é possível avaliar de uma forma mais eficiente o desgaste da ferr

2. Effect of cutting speed and cutting fluid on the BUE geometry of a SAE 12L14 free machining steel
A well known phenomenon, the "built-up edge - BUE", occurs at the chip/tool interface when multiphase materials are machined at low cutting speeds. Under high compressive stresses, seizure prevents the material from sliding over the tool’s rake face. Although many reports have been published on the subject, studies of the BUE phenomenon have been marked by

3. N. Machinability of low carbon free-machining leaded steel ABNT 12L14 with different levels of residual elements (chromium, nickel and cooper) / Usinabilidade do aço de corte-fácil baixo carbono ao chumbo ABNT 12L14 com diferentes níveis de elementos químicos residuais (cromo, níquel e cobre)
The purpose of this thesis was to study the machinability of low carbon free-machining leaded steel (ABNT/AISI 12L14) with different levels of residual (tramp) elements such as chromium, nickel and copper. Nine batches of steel were produced with controlled chemical composition, and with alterations in the mentioned residual levels so as to apply two levels
