Analiza obremenitev pri vrtanju

Križaj, Anže (author), Pušavec, Franci (mentor)

Vrtanje je zelo uporabljen proces odrezavanja. Pri tem procesu je potrebno pravilno na- staviti parametre, za čim bolj učinkovito delovanje. Najpobembnejša sta pomik orodja ter število obratov na minuto. Ko med vrtanjem zmanjšamo pomik na obdelovalnem stroju, se zaradi drsenja orodja po obdelovancu pojavi dodatna obremenitev, kar pov- zroči dodatno segrevanje orodja. Največji preskok pri HSCO vijačnih svedrih se zgodi pri približno 70% začetnega pomika, pri parametrih, ki jih priporoča proizvajalec.

• Title: Drilling load analysis

Abstract

Drilling is a very used cutting process. In this process it is necessary to correctly set up the parameters, for the most efficient operation. The most important are tool feed and spindle speed. When reducing feed on the machine, during the drilling, an additional load occurs due to the tool sliding on the workpiece, which cause heating up tool even more. The maximum load jump, when drilling with HSCO drills, occurs at approximately 70% of initial feed, at the recommended parameters by manufacturer.
