Obstojnost frezal konkurenčnih ponudnikov orodij pri obdelavi orodnega jekla v mehkem stanju

Kocjan, Rok (author), Kramar, Davorin (mentor)

V diplomskem delu je analizirana in primerjana obstojnost krogelnih frezal konkurenčnih ponudnikov pri obdelavi orodnega jekla v mehkem stanju. Na začetku diplomskega dela je predstavljen teoretični popis obdelovanja in frezanja skupaj z orodji, podrobneje pa so opisana krogelna frezala, ki so bila uporabljena pri eksperimentalnem delu. V nadaljevanju sledi teorija obdelovalnosti materialov in določevanje le te. Zatem sledi popis eksperimentalnega dela. Namen dela je, da štirim konkurenčnim ponudnikom frezal enake geometrije in materiala ter pri istih pogojih obdelave določimo sposobnost frezanja orodnega jekla v mehkem stanju. Iz dobljenih podatkov je narejena primerjava in določen je najboljši ponudnik. Za določitev sposobnosti frezanja frezala smo potrebovali naslednje meritve in podatke: hrapavost obdelane površine, obrabo frezala iz karbidne trdine ter obliko odrezkov. Rezultati so predstavljeni tabelno, slikovno ter grafično s potrebnimi dopisi.

• Title: Milling cutter tool life of competitive providers in machining of tool steel in the soft state

Abstract

In this thesis a method of resistance determination of spherical milling cutter of competitive providers at milling of tool steel at its soft state is analyzed and compared. At the beginning the theoretical background of milling processes together with the tools, and in more detail spherical milling cutters are described, which were used in experimental work. Later on theory material machinability follows and its determination. In the next part a report of the experimental work follows. The aim is to determine the ability of milling tool steel in soft state of four milling cutters of competitive providers of the same geometry and material at same conditions. From the collected data, the comparison is made and based on the results the best provider it is selected. For determination of the ability of milling tools the next measurements and data we needed: surface roughness, the tool wear of milling cutter from carbide milling tools and the chip form. The results and findings obtained with experiments and theoretical knowledge about milling are presented in figures and tables with following explanations.
