Modern approaches to face milling of hard-to-machine materials using PCBN tools

The article discusses innovative methods and technologies for face milling of hard-to-machine materials using polycrystalline cubic boron nitride (PCBN) tools. Special attention is paid to the analysis of the efficiency and durability of cutting tools equipped with superhard inserts, as well as to issues related to the optimisation of the milling process to achieve high quality and precision of the machined surface. The influence of various technological parameters on the stability and productivity of the milling process, as well as the wear characteristics of the cutting elements of the tool, are considered. Special attention is given to the comparison of the properties and characteristics of tool materials, in particular PCBN, with traditional cutting tool materials, demonstrating the advantages of using PCBN for machining difficult-to-machine materials. The results of analytical studies highlight the advantages of using PCBN tools over other tool materials. Recommendations are given for the selection of optimum cutting modes in order to increase the productivity of machine part production and the economic efficiency of the manufacturing process.
