Korchagin, Stanislav Production of wooden hollow spiral balusters on turn-milling CNC machines / Stanislav Korchagin, Mikhail Chernykh, Vladimír Štollmann. -- Obr., tab. -- Lit. - The esthetic perception of a hollow baluster with spiral grooves, the influence of the spiral line elevation angle value and number of passes on perception are presented in the paper. The variants of balusters implementation depending on the direction of the mill and workpiece feed during machining are demonstrated. The formulas characterizing the crosssection geometry with odd and even amounts of grooves are given. It is shown that the elevation angle of, approximately, 45˚ provides the most favorable esthetic perception. The production of balusters from wood and medium density fiberboard on a turn-milling CNC machine is examined. The recommendations on the groove milling sequence are proposed, the values of cutting depth and mill feed for certain typical sizes of balusters from birch and beech are recommended.
