Abstract

Cilj ovog rada je napraviti analizu trošenja alata kod finog glodanja kamena. Upotreba tvrdih metala za izradu reznih dijelova alata za obradu kamena u velikom je usponu. U sklopu ovog rada napravljeno je eksperimentalno ispitivanje kojem je cilj usporediti trošenje komercijalnog alata za fino glodanje kamena s oštricom od tvrdog metala s trošenjem alata čija je rezna oštrica napravljena od nanostrukturiranog tvdog metala. U prvom dijelu rada napravljen je pregled tehnologije obrade odvajanjem čestica glodanjem te pregled kamena kao materijala. Opisan je tvrdi metal kao materijal rezne oštrice alata te njegova nanostrukturirana inačica. Predstavljeni su i oblici trošenja alata te kako se postojanost rezne oštrice alata izražava u smjeru posmičnog gibanja. U drugom dijelu rada nalazi se opis eksperimentalnog dijela rada. Napravljena je CAM simulacija samog ispitivanja trošenja nakon kojeg je provedeno snimanje reznih oštrica alata industrijskom kamerom. Na temelju snimaka trošenja alata nakon ispitivanja donesen je zaključak o trošenju alata.

Abstract (english)

Main objective of this paper is the tool wear analysis in fine stone milling. The usage of hard metal for making cutting parts of tools for fine milling of stone is in great rise. For this paper an experiment was made to compare wear of comercially avaliable tool for fine stone milling with hard metal cutting blade and cutting tool with cutting blade made of nanostructured hard metal. In the first part of the paper there is given a overview of fine milling technology and stone as a material. Hard metal and its nanostructured version are described as a material for cutting part of the tool. There is also given an overview of types of wear and formulas for durability of cutting edges. In the second part of the paper there is a CAM simulation of examination after which was provided inspection of cutting edge with industrial camera. At the end there is given a conclusion based on recordings of wear after inspection.
