Summary:The global industry development is also reflected in the development of special engineering materials. These materials usually have special properties at high temperatures, such are tensile high strength and hardness. Due to this special properties, this materials usually have low machinability. Consequently, it is necessary to develop technologies for machining of mentioned materials, such are hybrid cutting processes. In this paper, the alloy steel X210Cr12 was turned, whereby the workpiece was heated. Heating, as secondary process, was performed by gas combustion, directly in point next to the point of the cutting tool action. Cutting forces were measured in the two cases: without heating, and by heating of workpiece. Effects analysis and process modeling were performed using Taguchi's experiment design, by combining the cutting parameters of primary process. The analysis showed significant reduction in cutting forces, but also poorer quality of machined surface. Conclusions were made about the possibilities of using this hybrid machining process in material machining.
