Invar 36 Alaşımının Seramik Takımlar ile İşlenmesinde Kesme Kuvveti Bileşenleri ve Yüzey Pürüzlülüğü Bakımından İşlenebilirliğinin Değerlendirilmesi.

Invar 36 is an alloy used in engineering applications where high dimensional stability is required in the field of space and aviation due to its low thermal expansion coefficient. In this study, the machinability of Invar 36 alloy has been evaluated in regard to the cutting force components (Fc, Ff and Fp) and surface roughness (Ra). The turning experiments were performed on dry conditions without using cooling liquid on a CNC lathe. The impact levels of the cutting parameters on the cutting force components and Ra are also determined with analysis of variance (Anova). The analysis results show that the feed rate has the highest significance on Fc, Ff, and Ra while the cutting depth has the highest significance on Fp. The minimum values for the cutting force components in the tests performed at a (Vc) of 240 m/min, at a (f) of 0.12 mm/rev and a (a) of 0.6 mm, have been measured as 95N, 80N, and 20N, respectively. The lowest Ra value was obtained as 0.452 µm as a result of the experiments performed at 180 m/min (Vc), 0.12 mm/rev (f) and 0.6 mm (a). [ABSTRACT FROM AUTHOR]
