Açıklama: <p><span style="color: rgb(34, 34, 34); font-family: Merriweather, serif; font-size: 18px;">In this study, the machinability of test pieces obtained from two different white cast irons, NiHARD-4 and HCWCI, were investigated by boring method, a machining process. The impacts of cutting parameters on cutting forces were identified. Analysis of variance was used to determine the effect ratios of the cutting parameters. Moreover, Taguchi analyses were used in the experiments to examine the impacts of cutting parameters on cutting forces. Considering the results in terms of dry and wet test conditions, it has been revealed that the cutting forces such as Fc, Fr and Ff of HCWCI material are lower than NiHARD-4 material in all test conditions. In dry cutting, high cutting speed and low feed have decreased the cutting forces. In wet cutting when the cutting speed has increased, Fr and Ff have increased. In terms of the cutting parameters, it was found that the most impact parameter on Fc is feed rate, the most impact parameter on Fr is material and the most impact parameter on Ff is cutting speed in dry cutting. In wet cutting, the most effective factor on Fc is feed rate, whereas the most effective factor on Fr and Ff is the material. Consequently, it can be said that to lower the cutting forces is required to reduce the feed rate and raise the cutting speed when NiHARD-4 and HCWCI materials are machined by boring operations with CBN inserts.</span></p>
