P20 Çeliğinin CBN ile Yüksek Hızlarda Frezelenmesi Sırasında Kesme Derinliği ve Genişliği Değerinin Aşınma ve Yüzey Pürüzlülüğüne Olan Etkisinin İncelenmesi
Abstract
Bu çalışmada 55 HRC’ye sertleştirilmiş P20 kalıp
çeliği; iki farklı tip CBN kesici takımla, yüksek hızlarda işlenmiştir.
Deneylerde kullanılan CBN kesici takımların birincisi düşük CBN katkılı
(CBN-DS) ve seramik bağlayıcılıdır. Diğeri ise yüksek CBN katkılı
(CBN-YM) ve metal bağlayıcılıdır. Elde edilen takım aşınması ve yüzey
pürüzlülüğü değerleri CBN kesici takımlar için karşılaştırılıp, kesme
derinliği, kesme genişliği, CBN oranı ve bağlayıcının takım aşınması ve
yüzey pürüzlülüğü üzerine etkisi araştırılmıştır.

Abstract
In this study P20 mold steel hardened to 55 HRC was machined by using two different types of cubic boron nitride cutting tools at high cutting speeds. One of the CBN tools used in the experiments is a low CBN content tool with a ceramic binder. The other one is a high CBN content tool with a metal binder. Tool wear and surface roughness results obtained with each type of tools were compared, and the effects of cutting depth, cutting width, CBN content and binder on tool wear and surface roughness were investigated.
