EFFECT OF TECHNOLOGY PARAMETERS ON SURFACE ROUGHNESS DURING CNC MILLING OF A2024 ALUMINUM ALLOY

Abstract

This paper presents experimental results on the effect of technological parameters on surface roughness in CNC milling of A2024 aluminum alloy using a high-speed steel end mill. The investigated parameters include cutting speed and feed rate. The experimental design method was applied to develop a mathematical model describing the relationship between the technological parameters and surface roughness. The results provide a basis for selecting optimal cutting conditions to improve surface quality and machining efficiency in production.
