Atanasov, Valentin Study of the influence of basic process parameters on the roughness of surfaces during milling of scots pine wood / Valentin Atanasov, Georgi Kovatchev, Tihomir Todorov. -- Graf., obr., tab. -- Experimental results in the processing of Scots pine (Pinus sylvestris L.). are presented in the paper. They were conducted under the manufacturing conditions. Three machines are used – two jointers with different knife spindle designs and with flat knives and replaceable rigid alloy plates – a helical cutter head, as well as a planer with flat knives. The measured parameter is Rz, and an electronic profilometer was used to measure its reading. The studies were conducted using the method of planned two-factor regression analysis. The selected factors are fundamental to the milling process – feed speed vf and radial depth of cut ae. Their levels of variation are determined on the basis of preliminary experiments, as well as the practical possibility of their realization. The results obtained with all three machines do not exceed 45 μm, and the ones for the planer make the strongest impression.
