Özet:

 Use of NiTi shape memory alloys are increasing due to functional and mechanical properties of these alloys. However, machinability of them quite poor because of thermal and mechanical properties of the alloy. In this context, the main problem is tool wear. The previous work have been planned with coated and uncoated carbide cutting tools and conventional cutting speed values. In this work, high-speed milling of shape memory alloys using carbide, CBN and whisker ceramic cutting tools and investigation of tool wear behaviors are aimed. The cutting speed values used in the experiments are as follows: 100, 200, 300 and 400 mmin. The tool wear analysis showed that tool life and tool wear behavior change upon the cutting speed value. At the cutting speed values of 100 and 200 mmin, carbide cutting tools performed a long tool life. When the cutting speed was increased to 300 and 400 mmin, it was seen that the tool life of ceramic and CBN cutting tools relatively increased and that of carbide and coated carbide tools dramatically decreased. The observed wear mechanisms are abrasive, adhesive, oxidative and chemical wear.

 NiTi şekil hafızalı alaşımların kullanımı, fonksiyonel ve mekanik özellikleri nedeniyle, gün geçtikçe artmaya başlamıştır. Öte yandan, alaşımın termal ve mekanik özellikleri nedeniyle talaşlı imalat ile işlenebilirliği oldukça güçtür. Bu kapsamda karşılaşılan problemlerin başında takım aşınması gelmektedir. Önceki araştırmalara bakıldığında, gerçekleştirilmiş çalışmaların karbür ve kaplamalı karbür kesici takımlar ile geleneksel kesme hızlarında planlandığı görülmektedir. Bu çalışmada şekil hafızalı alaşımların, karbür, CBN ve whisker seramik kesici takımlar ile yüksek kesme hızlarında frezelenmesi ve takım aşınması davranışlarının incelenmesi hedeflenmiştir. Deneylerde kullanılan kesme hızları şunlardır: 100, 200, 300 ve 400 mdk. Takım aşınması analizleri göstermiştir ki takım ömrü ve aşınma davranışı, kesme hızı değişimine göre değişiklik göstermektedir. 100 ve 200 mdk kesme hızlarında karbür ve kaplamalı karbür kesici takımlar yüksek kesme ömrü sergilemiştir. Kesme hızı 300 ve 400 mdk değerlerine arttırıldığında, seramik ve CBN kesici takımların kesme ömrünün nispeten arttığı, karbür ve kaplamalı karbür kesici takım ömürlerinin ciddi düzeyde azaldığı görülmüştür. Gözlemlenen aşınma mekanizmaları; abraziv, adeziv, oksidasyon ve kimyasal aşınma olarak sıralanabilir.
