The presented study concerned the effect of technological parameters such as feeding speed and sharpness angle on the surface roughness of three native wood species: beech, pine and black locust. The sharpness angle was investigated in range of 40-55° during milling with various values of feeding speeds. Milling process was carried out with the use of bottom spindle milling machine and roughness measurements were completed using stylus profilometer. In order to analyze the results simple linear regression analysis was done. It has been stated that in milling process linear upward trend of the surface roughness occurs with an increase in the feeding speed. However, the characteristic of this feature depends on the sharpness angle and wood species. In case of the sharpness angle, the best results were obtained for an angle in range of 40-45°. Designated linear regression lines were characterized by high coefficient of determination.
