Abstract


The impact of heat-treatment and plane milling parameters were evaluated relative to the surface quality of native and thermally modified oak wood (Quercus robur L.). Experimental wood samples were treated via ThermoWood technology at Volga State University of Technology in Yoshkar-Ola, Russia. The investigation focused on the impact of the tool (rake angle = 15°, 20°, and 30°), material (native wood, wood heat-treated at 160 °C, 180 °C, 200 °C, and 220 °C), cutting speed (20 m/s, 40 m/s, and 60 m/s), and feed rate (20 m/min, 40 m/min, and 60 m/min) on the machined surface quality (mean arithmetic deviation of the surface). The roughness measurement was performed via a contactless method with a laser profilometer. An analysis of variance and post-hoc Duncan test revealed the influence of the examined parameters on the surface roughness in the following order from highest to lowest: rake angle, cutting speed, heat treatment temperature, and feed rate. This research is part of a study of the properties of woodworking thermally modified wood that is focused on measuring the quality and energy of the machining process.
