Abstract

V diplomskem delu je predstavljena obdelovalna dinamika. Osredotočili smo se na pomen vibracij in hrupa, ki se pojavljata v obdelovalnem sistemu. V obdelovalnem procesu se nezaželene vibracije in hrup poskušajo zatreti, saj imajo slab vpliv na končni izgled obdelovanca. Skozi diplomsko delo so predstavljene vrste vibracij. Ločimo proste, prisilne in samovzbujajoče vibracije. Spoznali smo, da so samovzbujajoče vibracije oziroma hrup najmanj zaželene in jih je tudi težko nadzorovati/zatreti. Te vibracije ne vplivajo samo na sam potek obdelovalnega sistema, ampak lahko pustijo tudi posledice na ljudeh. V obdelovalnem sistemu se pogosto pojavlja strukturalni hrup, ki se ga deli na mehanski, vibracijski in elektromagnetni hrup. S samim nadzorom vibracij lahko vplivamo na jakost in moč vibracij ter hrupa v obdelovalnem procesu. Že s samim spreminjanjem procesnih parametrov, zamenjavo orodja, izolacije ter z izboljšanjem togosti obdelovanca lahko pripomoremo k boljšemu nadzoru hrupa in vibracij v obdelovalnem sistemu.

Secondary title:	Vibrations in machining systems
Secondary abstract:	The intention of this diploma thesis work is to present different machining dynamics. We have focused on the importance of vibrations and noise, that can occur in the process of machining systems. Unwanted vibrations and noise are tried to be suppressed, as they have a bad effect on the final appearance of the workpiece. Different types of vibrations are presented through this diploma work. We separate between free, forced and self-exciting vibrations. We have established that self-excited vibrations or noise are the least desirable and also the most difficult to control and suppress. These vibrations not only affect the course of the processing system, but can also have consequences for humans as well. Structural noise often occurs in the machining sytems which is divided into mechanical, vibrational and electromagnetic noise. We can control vibrations by influencing the strength and power of these vibrations that occur in the machining process. We can contribute to better control of noise and vibrations caused in these systems by changing the process parameters, changing the tools or equipment that are being used, improving sound insulations and increasing the rigidity of the workpiece itself.
