Merjenje obrabe rezalnih ploščic na sodobnih CNC obdelovalnih strojih

Ozmec, Vid (author), Pušavec, Franci (mentor)

Zaključna naloga obravnava tematiko, povezano z merjenjem obrabe rezalnih orodij, ki jo povzročajo različni mehanizmi. V teoretičnem delu zaključne naloge so predstavljeni različni tipi obrabe in lomov rezalnih orodij. Opisano je, kako lahko poškodbe preprečimo že v začetnih fazah obdelovalnega procesa. Podrobneje so predstavljeni različni mehanizmi obrabe in njihova korelacija s hitrostjo odrezavanja, mehanskimi lastnostmi materialov in temperature, ki se razvije v rezalni coni. V glavnem delu zaključne naloge sta predstavljena zgradba in delovanje treh merilnih sistemov, s katerimi lahko obrabo natančno določimo.

Abstract

The following thesis examines measurment of the tool wear, which is caused by several wear mechanisms. Different types of tool wear and tool fracture are presented in theoretical part of the thesis. It is discussed, how tool damage can be prevented in the beginning phase of the milling process. Different wear mechanisms and their correlation with cutting speed, mechanical properties and temperature in the cutting zone are explained in detail. Structure and operation of the measurment system are described in the main part of the thesis.
