This paper investigates the influence of technological parameters such as spindle speed n and feed rate F on the surface quality of cuts during milling. Experiments were conducted using a CNC milling machine FA4060 with 6 mm thick mahogany wood. Surface quality was evaluated through the surface roughness of the cut. The Taguchi experimental design method was used to assess the influence of each individual parameter on surface roughness. The minimum surface roughness achieved was 1.059 µm corresponding to a spindle speed of 12000 RPM and a feed rate of 200 mm/min. Analysis using the Taguchi method showed that surface roughness was mainly affected by the feed rate, while spindle speed had less influence.
