RESUMO

The purpose of this research is the study of the surface roughness of turned workpieces. One of the specific purpose is the possibility of using the workpiece surface roughness as a tool life criterion of single point carbide tools. The study of influence of cutting speed, feed and tool wear is another specific purpose. Several turning tests were performed with ABNT 1045 steel using tests were several cutting speeds and feeds. Some of these performed five or ten times and the surface roughness of the workpieces were measured using Ra and Rmax as parameters. Besides, the wear of several tools were measured too. One of the most important conclusions of this research is that and Rmax the tool life prediction using limit values of Ra is a reliable procedure and can he used under industrial conditions
