$a Evaluation of the surface quality of the processed wood material depending on the construction of the wood milling tool $f Pavlin Vitchev 215 $c Obr., tab. 320 $a Lit. 330 $a The aim of the current study is to investigate the changes in the surface quality of specimens from Scots pine (Pinus Sylvestris L.) wood during longitudinal milling. Further, the influence of the cutter head construction of three different cutting tools (CH-1, CH-2, CH-3) on the surface quality wasevaluated at different rotational frequencies n (from4000 min-1to 8000 min-1) and feed speedvf(from3.5 m·min-1to10.5 m·min-1).The surface roughness was measured with a digital profilometer, model„Surf testSJ-210“ (Mitutoyo, Japan). Based on the experimental results, three regression equations are derived and thechanges in the roughness parameter Rz in relation to the evaluated factors are graphically presented. Our results show that the values of the roughness parameter range from 25.7 μm to 39.6 μm.The highest surface quality is achieved when the surface is processed with the cutting tool CH-3, which cutting teeth edges are located at a certain angle (30°) to the axis of cutting rotation. The optimal values of the evaluated variables, at which the height qualityof the processed surfaces is achieved, are as follows: rotational frequency n= 6500 min-1,at which the reached cutting speed is vc= 42 m·s-1, and feed speed is vf= 7 m·min-1. 463 -1
