Abstract
Section titled āAbstractāIn 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 MuÄla 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.
