Abstract
The C110 steel is used in oil industry applications where it is exposed to a highly corrosive aqueous environment. In order to verify the resistance of this steel to corrosion, tests are carried out, such as the corrosion under voltage, regulated by the standard NACE TM0177. The test specimens for this test are manufactured by a series of operation procedures, initializing by turning operation. Subsequently, as the specimen must have a surface roughness Ra maximum of 0,250 μm, it is necessary to do a grinding process. The main aim of this paper is to analyses a turning proposes in order to eliminate the need of a grinding process. For this, it was analyzed the behavior of roughness parameters, such as Ra, Rq, and Rz surface machined in test specimens using carbide and cermet tools with the same cutting speed varying the feed rate (0.05; 0.10; 0.15) mm/rev. Results showed that it was not possible to reach the roughness limit of 0.025 μm using the parameters of this work. The best value founded was of 0.0277 μm, using hard metal and feed rate of 0.05 mm/rev value relatively close to. Further studies should be necessary to verify the feasibility of eliminating gridding finishing by just using turning operation.
