AISI D2 Çeliğinin Yüzey Frezelemesinde Nano/Tabakalı Sert Kaplamaların Kesme Performansının İncelenmesi

Kalıp döküm endüstrisinde, çeliklerin sertleştirilmiş durumda frezelenmesi yaygındır. Daha iyi bir yüzey kalitesi için bu işlem sırasında oluşan takım aşınması ve kesme kuvvetleri dikkate alınmalıdır. Bu çalışmada, nano katmanlı AlTiN/TiN kaplı karbür kesici takımların AISI D2 yüzey frezelemede kesme performansı incelenmiştir. Kesme performansı karşılaştırmak için tek katmanlı sert kaplamalı karbür kesici takımlar ve kaplamasız kesici takımlar kullanılmıştır. Tüm kesme hızlarında, nano katmanlı AlTiN/TiN kaplı karbür kesici takım, TiAlN ve TiN kaplı olanlardan ve kaplamasız takımdan daha uzun takım ömrü sergilemiştir. Tüm kesici takımlarda çentik aşınması ve yığma kenar oluşumu etkin aşınmaları olduğu görülmüştür. Tüm parametrelerde nano katmanlı AlTiN/TiN sert kaplamalar kullanılarak daha düşük kesme kuvveti değerleri ölçülmüştür.

Investigation of Cutting Performance of Nano/Layered Hard Coatings in Face Milling of AISI D2 Steel

In the die-molding industry, milling steels in a hardened condition is common. Tool wear and cutting-forces occurring during this process must be considered for better surface quality. The cutting performance of nano-layered AlTiN/TiN coated carbide cutting-tools in AISI D2 face-milling was evaluated in this work. Single-layer hard-coated carbide cutting-tools and uncoated cutting-tools were used to compare cutting performance testing. All cutting-speeds nano-layer AlTiN/TiN coated carbide cutting tool presented longer cutting-length than TiAlN and TiN coated ones and uncoated tool. Notch wear is an overriding wear mechanism, followed by build-up edge formation for all cutting-tools. Using a nano-layer AlTiN / TiN hard-coating, cutting-force values were lowered in all experiments.
