Özet:

In this study, the processability of the Nimax and Toolox 44 materials between the patterns of steel was experimentally studied. Cutting trials were performed with three different cutting speeds (50-70-90 m/min), progress (0,04-0,08-0,12 mm/tand) and a fixed cutting depth (1,5 mm) using CVD-AlCrN-covered carbury finger freeze. The results of the experiments found that in the processing of Toolox 44 under the same conditions there was more cutting strength and surface smoothness than Nimax. The optimum cutting parameters in the processing of the Nimax material are high cutting speed and low progress (V:90 m/min, f:0,04 mm/tand), while in Toolox 44 low cutting speed and progress (V:50 m/min, f:0,04 mm/tand). With the increase in the cutting speed from 50 m/min to 90 m/min, the cutting force in Toolox 44 was observed by 0.04-0.08 and 0.12 mm/dental advancement values, respectively, by 140,139 percent; by 11,286 percent and by 15,179 percent, while in Nimax by 3,221 percent; by 2,974 percent and by 5,062 percent. Similarly, with the increase in cutting speed, the surface smoothness in Toolox 44 was found to be reduced by 0.04-0.08 and 0.12 mm/dental progress values by 78.162 per cent, 34.721 per cent and 8.878 per cent, while in Nimax it was reduced by 3.515 per cent, 30.027 per cent and 9806 per cent. According to the processed surface six images, the processed surface in Nimax has grown a hole with an increase in progress, while in Toolox 44, the deformed and heat-affected layer has grown. Furthermore, the same progress parameters found that more progress traces were found on the processed surfaces of Toolox 44 than Nimax and that this also increased the surface smoothness.
