Bu çalışmada, farklı yapısal özelliklere sahip mermerlerin frezelemesinde vakumlu lehimleme yöntemiyle kaplanmış freze takımlar (T301, T405, T602) kullanılarak elmas tane boyutunun kesme kuvvetleri ve spesifik enerji parametrelerine olan etkileri araştırılmıştır. Mermerler, doğal yapı malzemesi olarak farklı fiziksel ve mekanik özelliklerinden dolayı tipik olarak işlenmesi zor malzemelerdir. Deneylerde granoblastik dokuya sahip ince mineral taneli Bursa Beyaz mermer, kristalin dokuya sahip iri mineral taneli Muğla Beyaz mermer kullanılmıştır. Yeni geliştirilmiş olan vakumlu lehimleme teknolojisi ile üretilen elmas kaplamalı freze takımlar kullanılmıştır. Frezeleme işlemlerinde 6000-10000-12000 rpm kesme devri, 1500-2250-3000 mm/min ilerleme hızı parametreleri uygulandı. Frezeleme süresince Dik yönde etki eden FZ (N) değeri, kesme kuvveti Fc (N) değeri ve spesifik enerji değerleri araştırılarak elmas tane boyutlarının etkileri incelenmiştir. Sonuç olarak T602 elmas takımların diğer takımlara göre daha iyi kesme performansı göstermiştir. Mermerlerin yapısal özelliklerinin kesme performansı üzerinde etkili olduğu tespit edilmiştir.

Effect of Diamond Grain Sizes on Cutting Forces and Specific Energy in Marble Milling Processes

Öz

In this study, the effects of diamond grain size on cutting forces and specific energy parameters were investigated using vacuum brazed coated milling tools (T301, T405, T602) for milling marbles with different structural properties. Marbles, as natural building materials, are typically difficult to machine due to their different physical and mechanical properties. Bursa White marble with fine mineral grains with granoblastic texture and Muğla White marble with coarse mineral grains with crystalline texture were used in the experiments. Diamond coated milling tools produced by the newly developed vacuum brazing technology were used. In milling operations, 6000-10000-12000 rpm cutting speed, 1500-2250-3000 mm/min feed rate parameters were applied. The effects of diamond grain sizes were analyzed by investigating the FZ (N) value, cutting force Fc (N) value and specific energy values acting in the perpendicular direction during milling. As a result, T602 diamond tools showed better cutting performance than other tools. It was determined that the structural properties of marbles have an effect on cutting performance.
