Bu çalışmada, Alüminyum 6061 malzeme kuru ve MQL (minimum miktarda yağlama) şartları altında frezelenmiştir. MQL yönteminde hem katkısız hem de nano MoS2 (Molibden disülfür) katkılı bitkisel kesme sıvısı kullanılmış ve kesme kuvveti bileşenleri ve yüzey pürüzlülüğü incelenmiştir. Frezeleme işlemleri, CNC dik işleme merkezinde sabit kesme derinliği (1.5 mm), ilerleme (0.1 mm/dev) ve kesme hızı (250 m/dak) değerlerinde gerçekleştirilmiştir. MQL yönteminde, kesme sıvısı tek nozülden 26 ml/saat ve 52 ml/saat olmak üzere iki farklı debide kesme bölgesine gönderilmiştir. Yapılan deneysel çalışmalar sonucunda, MQL yönteminde yüksek debide kesme bölgesine gönderilen nano akışkanın kesme kuvvetlerini ve yüzey pürüzlülüğünü azalttığı belirlenmiştir.
