The paper presents the result of an investigation of cemented carbides cutting tools performance in interrupted turning of Inconel 718. The discussion is based on case study revealed from industry experience. The spacing created for operational reasons cause interruption in turning process what has crucial effect on tool life and wear. Furthermore cutting parameters and tool geometry have significant influence on creating burr at the edge of spacing which leads dimensional deviation. The research based on two stages, preliminary and modelling, was introduced. In the first an effect of cutting speed, feed, depth of cut, rake angle and tool major cutting edge angle on wear and burr size was investigated. The second step was a regression based modelling of major parameter influence on various process aspects such as values of forces, tool wear and burr size. It was found that the consequential effect on plastic deformation of edge and tool performance have depth of cut. It also has been proven that higher cutting speed, lower values of angles provides better quality of machined element. The paper gives recommendations for turning parameters selection to acceptable burr forms, tool life and process performance.
