Features of the face milling process using cubic boron nitride tools

This article discusses the theoretical aspects of machinability of hard-to-machine materials during face milling using tools made from cubic boron nitride (CBN). The main focus is on analyzing the physical and mechanical properties of CBN tools, which make this material effective for machining hard materials, as well as how different cutting parameters affect the roughness of the machined surface. CBN tools are characterized by high hardness and wear resistance, allowing them to withstand high temperatures and mechanical loads during the milling process. Thanks to these properties, they can significantly improve the machining efficiency and ensure the high quality of the machined surface of hard-to-machine materials. The theoretical analysis also includes considering optimal cutting parameters, such as cutting speed, depth of cut, and feed rate. It is determined that a rational choice of these parameters can significantly reduce tool wear and improve machining quality. Special attention is paid to cutting parameters such as cutting speed and feed rate, which can significantly influence the temperature regime in the cutting zone and, consequently, the tool wear resistance and the quality of the machined surface. Overall, the article emphasizes the importance of using CBN tools for face milling of hard-to-machine materials and the need for optimization of technological parameters to achieve maximum process efficiency.
