Obdelava keramike - Macor

Fink, Domen (author), Pušavec, Franci (mentor)

Zaključna naloga obravnava glavne lastnosti keramike Macor, ki so pomembne pri njeni uporabi in postopkih doseganja željene oblike. Njena najpomembnejša značilnost je sposobnost obdelave s postopki odrezovanja. Gre za obdelavo nevsakdanjega materiala s specifičnimi lastnostmi, zato so bile v nalogi podane smernice za obdelavo na konvencionalnih frezalnih strojih z orodji za obdelavo kovin. Izdelalana sta bila 2 reprezentativna izdelka na frezalnem stroju. Za vsak posamezen izdelek je bil uporabljen drug material orodja, enkrat iz hitroreznega jekla in enkrat iz karbidne trdnine. Analiza izdelkov je bila opravljena z digitalnim mikroskopom in je pokazala, da je površina izdelka obdelana z orodjem iz karbidne trdine boljša, krušenje robov na vhodu in izhodu orodja v material pa manjše. Na vhodni strani prihaja do krušenja robu na površini, ki je obdelana istosmerno, na izhodu pa na robu površine obdelane protismerno.

• Title: Machining of Macor ceramic

Abstract

The thesis contains the main properties of Macor ceramic, which are important for its use and during processing for achieving the desired shape. Its most important feature is the ability to be machined. The processing is unusual, as the material with specific properties is used, that is why in this thesis there are provided guidelines for machining this ceramic on conventional milling machines with metalworking tools. Two representative products were made on a milling machine. For each sample a different tool material was used, one from high-speed steel and one from tungsten carbide. The analysis of the products was made with a digital microscope, and it showed that the surface of the product treated with carbide tool is better. The chipping of the edges at the tool entrance and exit into the material is smaller. The chipping is noticed at the entrance of the tool where it is downmilled, and at the exit where it is upmilled.
