EFFECT OF TECHNOLOGICAL PARAMETERS ON TOOL WEAR IN MACHINING A2024 ALUMINUM ALLOY ON CNC MILLING MACHINE

Abstract

This study analyzes the influence of technological parameters on tool wear during the machining of A2024 aluminum alloy on an X.mill M640 milling machine. The experiments were conducted using a high-speed steel end mill, focusing on two main parameters: cutting speed V and feed rate s. Experimental data were used to develop a mathematical model describing the relationship between tool wear and cutting parameters. The results show that both V and s significantly affect tool wear; in particular, an increase in feed rate leads to a rapid rise in wear, while the effect of cutting speed depends on the cutting conditions and the dominant wear mechanisms.
