Abstract
The paper presents the laboratory measurements results of temperature distribution in the cutting zone during orthogonal turning of a GrDe 2 titanium tube. The cutting tool used during the tests was a bimetallic cut-off tool with an uncoated insert made of P10 sintered carbide. The test plan was developed using the miniTab16 computer application and the Taguchi method. The tests were performed in accordance with orthogonal table l9, which describes nine cutting trials for two independent factors, cutting speed vc [m/min] and feed rate f [mm/rev], at three different values. The temperature distribution in the cutting zone was measured by means of a flIr sC 620 thermal imaging camera. The archiving and processing of measurement results was performed with the ThermaCamresearcher Pro 2.9 computer application. The obtained results were used to determine the average temperature for each of the nine trials; then, a statistical analysis of the results was performed.
