The paper presents the measurement results of the kinetic friction coefficient on wooden specimens. The measurements were carried out according to the „disc-block” friction pair method. Blocks and discs are made of five different types of wood-beech, ash, oak, pine, and fir. Experimental investigations were performed for different values of disc speed (rpm) and with different normal loads on the block. The obtained results indicate that the contact pairs of wood with higher surface hardness have higher values of the kinetic friction coefficient and vice versa. The values of the kinetic friction coefficient had approximately constant values for different experimental conditions with the tendency of a slight decrease while increasing normal load and the speed (number of rpm). © 2019, Faculty of Engineering, University of Kragujevac.
