Tekstürlü kesici takımların Ti6Al4V alaşımının ortogonal kesilmesindeki etkinliğinin araştırılması: nümerik bir yaklaşım
Öz
Bu araştırma, mikro
textürlü kesici takımların Ti6Al4V alaşımının kuru ortogonal kesilmesindeki
etkinliğini, 2D nümerik analiz yöntemi kullanarak incelemektedir. Bu maksatla,
farklı boyutlardaki mikro kanalları, kesici takımların talaş yüzeyi üzerinde
oluşturulmuştur. Bunun üzerine ortogonal kesme simülasyonları, farklı talaş
açısına sahip takımlar kullanılarak gerçekleştirilmiştir. Takım-talaş ara yüzündeki
temas mesafesi, kesme kuvvetleri ve kuvvet oranı sonuçları, mikro kanalların
performansına odaklanılarak değerlendirildi. Amaç, tekstürlü kesici takımların
geliştirilmesindeki bilgi birikimine katkı sağlayarak, proses veriminin
arttırılması ve negatif çevresel etkilerin minimize edilmesidir. Simülasyon
sonuçları, tekstürlü kesici takımların kullanımı ile daha düşük kesme
kuvvetleri, kuvvet oranı ve temas mesafesi elde etmenin mümkün olduğunu
göstermiştir. Ancak, tekstür parametrelerinin hatalı seçimi, artan sürtünme
gibi, ters etkilere de neden olabilmektedir. Buradan hareketle, mikro
kanalların etkinliğinin hem kanal boyutuna hem de talaş açısına bağlı olduğu
söylenebilir.

Efficiency investigations of textured cutting tools in orthogonal cutting of Ti6Al4V alloy: a numerical approach
Öz
This paper investigates efficiency of micro-textured cutting tools in
dry orthogonal turning of Ti6Al4V alloy using 2D numerical analysis. For this
purpose, micro-grooves at different sizes were generated on rake face of
cutting tools. Then, orthogonal cutting simulations were conducted using
different tool rake angle values. Contact length at tool-chip interface,
cutting force and force ratio results were evaluated focusing on performance of
micro grooves. The aim was to improve process efficiency and minimize negative
environmental impacts by contributing knowledge in development of textured
cutting tools. The simulation results revealed that decreased forces, force
ratio and contact length is possible with use of textured cutting tools.
However, improper selection of texture parameters may cause adverse effects
such as increased friction. Accordingly, efficiency of micro-grooves relies on
both, groove size and rake angle.
