Abstract: This article examines the determination of the basic cutting parameters with a view to minimizing the machining time of aluminum alloys in CNC machining centers while ensuring the required workpiece quality. The optimal selection of these parameters is of great importance for the productivity improvement and energy-efficient processing of aluminum alloys in such machine tools. The research is conducted for a type of serially produced workpieces. Taking into account the features of the machining center used, a 3D geometric model of the machining workpiece has been developed using the SolidWorks software. Based on the functional requirements for the workpiece, a type of aluminum alloy is chosen as the appropriate material. The properties of this material, the geometry of the tools used and the machining conditions are discussed in detail. After the analysis conducted, the main practical approaches to improving productivity have been formulated, which are reduced to: using the capabilities of the CNC system, developing a special device for clamping the workpiece, optimizing the control and positioning system of the tool magazine, selecting appropriate cutting parameters, designing specialized tools, implementing control algorithms and applying effective auxiliary functions. The research carried out and the results obtained can be used in the adjustment of the considered type of machining centers for the production of aluminum alloy workpieces. The proposed analytical–experimental approach can be integrated into CNC machine tools monitoring systems to support real-time diagnostics and condition-based maintenance.
