ABSTRACT Introduction. The temperature generated in the machining zone is a critical parameter that aff ects the dimensional accuracy, surface quality, material properties of the workpiece, and tool wear resistance. This is especially important when machining critical components for machinery operating under severe conditions. Such parts are typically made from heat-resistant alloys, with titanium nickelide (nitinol) being a notable example. Temperature can be infl uenced by various methods, but the primary approach used in this study was the selection of rational machining parameters. The purpose of this work is to evaluate the impact of cutting parameters on the temperature generated during the machining of titanium nickelide workpieces. Materials and methods. Experimental studies were conducted on the turning of titanium nickelide (TN-1) workpieces. The variable parameters in the tests were the cutting parameters: cutting speed V (m/min), feed rate S (mm/ rev), and depth of cut t (mm). The temperature T (°C) generated during machining was measured using a CEM DT-9897 thermal imager. The machining process was recorded during the tests, and was later reviewed to determine the peak cutting temperature. This value was taken as the average cutting temperature, as its maximum occurs at the contact point between the chip and the workpiece’s front surface, which is obscured from direct observation by the chip itself. Results and discussion. The following results are obtained during the research: experimental studies are conducted according to a developed plan, and the cutting temperature generated under various turning modes of TN-1 titanium nickelide workpieces are determined; mathematical dependencies of temperature on cutting parameters are established; verifi cation of the obtained dependencies is performed by comparing calculated cutting temperatures with experimental data (it is found that, according to the derived dependencies, the calculation error does not exceed 5.8%); rational turning modes for titanium nickelide workpieces are established based on cutting temperature, and recommendations for selecting cutting parameters for fi nish and semi-fi nish machining are developed.
