Vitchev, Pavlin The influence of some factors on the vibrations generated by woodworking spindle moulder machine when processing specimens from beech wood / Pavlin Vitchev, Zhivko Gochev, Georgi Vukov. -- Graf., obr., tab. -- Lit. - The general dynamic behavior of a woodworking spindle moulder machine, determined by the mean square value of the vibration speed (vrms,mm·s-1) measured on the shaft bearingsis investigated in the study. Among the measured factors, the cutting speed (Vc) has the greatest influence on the vibration intensity, followed by the feed rate (Vf) and the depth of milling (h). The results show that the vibration velocity varies in the range from 2 to 8 mm·s-1at the different values of the variable factors. On the basis of this results, with regard to the magnitude of the overall vibrations generated by the used milling machine in processing specimens of beech wood (Fagus sylvaticaL.), the following optimum values are recommended: cutting speed Vcε (34÷40) m·s-1; feed speed Vf up to 4 m·min-1; cutting depth hup to 8 mm. In cases when h>8 mm, the recommended feed speed is Vf< 3.5 m·min-1. Based on the presented graphical relationships, the optimum values of the studied factors can be determined in order to reduce the overall vibration of the machine, which is an important prerequisite for the good work of the cutting tool and for improving the quality of the machined surfaces during processing the specimens from beech wood.
