Östemperlenmiş Sfero Dökme Demir (GGG70) Malzemenin Frezelenmesinde Proses Parametrelerinin Arı Algoritması ile Optimizasyonu.

The machinability of a material depends not only on its mechanical properties and microstructure, but also on the selection and control of process variables. By changing the cutting fluid, speed and depth in GGG-70 material, channels have been opened on the material surface by milling process with a width of 10 mm and a length of 50 mm. The machining process was carried out using a minimum amount of lubricant (MQL). As a result of experiments with different processing parameters, the surface roughness and surface hardness of the material were measured. Compared to the uncut surface hardness, an average hardness reduction of 2%-10% occurred as a result of milling. The level of cutting parameters did not cause a statistically significant change in the surface hardness value. The mathematical model between different cutting parameters and surface roughness was obtained decisively by regression analysis. The optimum parameters of the cutting fluid, its speed and depth were found by the Bees Algorithm, which is a meta-heuristic methods optimization method. According to the Bees Algorithm, the optimum milling conditions are vegetable oil, 180 m/min cutting speed and 0.5 mm cutting depth. Especially, the optimum performance of vegetable oil compared to boron oil is important from the point of view of sustainable environment. [ABSTRACT FROM AUTHOR]
