Abstract

This paper aims to quantify the surface roughness after the CNC milling of selected wood species. Optimization of the essential milling parameters, rotational speed, and feed speed is desirable for reducing surface roughness. Both technological parameters significantly contribute to the amount of feed per tooth, affecting surface roughness. In the experiment, three economically important wood species were compared – beech, oak, and spruce wood. In addition, the zones of sapwood, mature wood, and false heartwood were evaluated in beech wood. The surface roughness after milling was assessed using the Keyence VHX-7000 digital microscope. The main result of the experiment is represented by the determination of the combination of the parameters mentioned above that produces the lowest roughness. In addition, roughness measurements were supplemented by microscopic analysis to explain roughness changes occurring on the surface.
