Effect of chip thickness, wood cross-sections, and cutting speed on surface roughness and cutting power during up-milling of beech wood

The aim of the conducted experiments was to determine effect selected machining parameters on power consumption and surface quality obtained during milling beech wood using a computerized numerical control woodworking machine. Surface roughness tested contact measurement method, while Ra Rz were recorded cutting energy determined. Tests for two variants speed (7.5 15 m·s-1) as well three chip thickness (0.10, 0.06, 0.02 mm); additionally, tests examined different cross-sections wood. It found that greater feed caused an increase in power. In turn, had no roughness, whereas its resulted increased at radial tangential comparable, it transverse cross-section. also lowest cross-section, greatest
