Abstract in Portuguese
Corpos de prova de ferro fundido foram usinados com altíssima velocidade de corte. Tiveram diversos parâmetros de sua rugosidade medida e os valores foram descritos em gráficos de rugosidade versus profundidade de corte. Pode-se verificar uma dependência entre estes valores, mas não o clássico aumento da rugosidade conforme o aumento da profundidade de corte. Realizou-se ainda a inspeção metalográfica dos corpos de prova na busca de mudanças de fase na estrutura ferro carbono que indiquem temperaturas elevadas no local, causadas pela alta velocidade de corte.

Abstract in English
Cast iron test parts were high-speed machined. They had several roughness parameters measured and these values were plotted on roughness versus depth of cut charts. It could be noticed a relation between these values, but not the classical roughness increase due to the increase of depth of cut. Moreover, the metalographical analisys was performed for these test parts, in a search for phase changes on the carbon-iron structure which indicate high temperatures at the region, caused by the high cutting speed.
