Bu çalışmada Ti6Al4V alaşımının mikro frezelenmesinde kesme hızı, ilerleme hızı ve soğutma
yönteminin kesme kuvvetine olan etkileri deneysel ve sayısal olarak belirlenmiştir. Ti6Al4V alaşımlarının
geleneksel soğutma yöntemleriyle işlenmesi işlenebilirliği kısıtlamaktadır. Bu çalışmanın amacı Ti6Al4V
alaşımını farklı soğutma yöntemleri (minimum miktarda yağlama(MMY) ve kuru) ve işleme
parametrelerinin uygulanmasıyla işlenebilirliğini artırmaktır. İşleme parametreleri, kesme hızı (25000,
30.000 ve 35.000 rpm), ilerleme hızı (0,12, 0,15 ve 0,175 mm/dev) ve kesme derinliği (0,02 mm) olarak
seçilmiştir. Bu çalışma sonucunda deneysel sonuçların sonlu elemanlar analizi sonuçlarına oldukça yakın
olduğu belirlenmiştir. MMY soğutma yöntemi kuru işlemeye göre hem deneysel hem de analiz
sonuçlarına göre kesme kuvvetini azaltmıştır. Kesme hızının artması kesme kuvvetini azaltırken ilerleme
hızının artması kesme kuvvetini artırmıştır.
