Abstract

Stainless steel materials have been used in many areas such as automotive, food, medical, chemical etc. by performing machining operations although having low thermal conductivity and work hardening tendency during machining. Cutting fluids have been applied in the machining of these materials. However, the cutting fluids have disadvantages such as harmful to the environment and health and the cost increment due to plenty of usage. Therefore, in this study, MWCNT (Multi-Walled Carbon Nanotube) reinforced commercial vegetable cutting fluid and WC (Tungsten Carbide) cutting tool were used in the milling of ferritic stainless steel by MQL (Minimum Quantity Lubrication) method. MWCNT particles were added to the cutting fluid at ratios of 0.1%wt., 0.15%wt. and 0.2%wt. to improve its cooling and lubricating properties. The effects of MWCNT particles, mixture ratios, and MQL flow rate on the cutting temperature occurred during milling operation were determined. The addition of MWCNT to the cutting fluid caused a decrement on the cutting temperature. However, an increment was observed when mixture ratio was further increased. Additionally, increasing of MQL flow rate reduced the cutting temperature

Özet

Paslanmaz çelik malzemeler, talaşlı şekillendirme sırasında gösterdikleri pekleşme eğilimleri ve düşük ısıl iletkenliklerine rağmen otomotiv, gıda, medikal, kimya vb. birçok alanda talaşlı şekillendirme uygulanarak kullanılmaktadırlar. Bu malzemelerin talaşlı şekillendirilmesinde çeşitli kesme sıvıları kullanılmaktadır. Ancak kesme sıvılarının çevre ve sağlık açısından zararlı olması ve bol miktarda kullanılmalarından doğan maliyet artışı gibi dezavantajları bulunmaktadır. Bu sebeple, bu çalışmada, AISI 430 ferritik paslanmaz çeliğin MQL (Minimum Miktarda Yağlama) yöntemi kullanılarak frezelenmesinde WC (Tungsten Karbür) kesici takım ve MWCNT (çok duvarlı karbon nanotüp) katkılı ticari bitkisel kesme sıvısı kullanılmıştır. Kesme sıvısının soğutma ve yağlama özelliklerini arttırabilmek amacıyla ağırlıkça %0,1, %0,15 ve %0,2 oranlarında MWCNT katılmıştır. MWCNT parçacıkların, karışım oranlarının ve MQL debisinin, frezeleme işlemi sırasında oluşan kesme sıcaklığına etkileri belirlenmiştir. Bitkisel kesme sıvısına MWCNT katkısı, kesme sıcaklığının azalmasına neden olmuştur. Ancak katkı oranı fazla arttırıldığında, kesme sıcaklıklarında bir miktar artış gözlemlenmiştir. Ayrıca, MQL debisinin arttırılması da kesme sıcaklıklarının azalmasını sağlamıştır
