Bu çalışma, AISI P20 çeliğinin işlenmesinde kesme kuvveti (Fc) ve yüzey pürüzlülüğü (Ra) üzerinde etkili olan kesme parametrelerinin optimize edilmesine odaklanmaktadır. Tornalama deneyleri Taguchi L9 ortogonal dizisine göre üç farklı kesme hızında (Vc) (120, 180 ve 240 m/dak), üç farklı ilerleme hızında (f) (0.12 0.21 ve 0.3 mm/dev) ve üç farklı talaş derinliğinde a) (0,4, 0,8 ve 1,2 mm) CNC torna tezgahında gerçekleştirilmiştir. Kesme parametrelerinin Fc ve Ra üzerindeki etki düzeyleri varyans analizi (Anova) ile belirlenmiştir. Analiz sonuçları, talaş derinliğinin kesme kuvvetini etkileyen en önemli parametre olduğunu, ilerleme hızının ise yüzey pürüzlülüğünü etkileyen en önemli parametre olduğunu göstermektedir. Dahası, analiz sonuçlar, 240 m/dk kesme hızı, 0.12 mm/dev ilerleme hızı ve 0.4 mm talaş derinliği çıktı parametreleri (Fc ve Ra) için optimum kesme parametreleri olduğunu göstermektedir. Optimum kesme parametrelerinde yapılan tornalama deneylerinde en düşük Fc ve Ra değerleri sırasıyla 178N ve 0.412 µm olarak ölçülmüştür.

This study focuses on optimizing cutting parameters effective on cutting force (Fc) and surface roughness (Ra) in the machining of AISI P20 steel. The turning experiments have been performed in CNC lathe at three different cutting speeds (Vc) (120, 180, and 240 m/min), three different feed rates (f) (0.12 0.21 and 0.3 mm/rev), and three different depths of cut (a) (0.4, 0.8, and 1.2 mm) according to Taguchi L9 orthogonal array. The effect levels of the cutting parameters on Fc and Ra have been determined with analysis of variance (Anova). The analysis results indicate that the depth of cut is the most significant parameter affecting Fc while the feed rate is the most significant parameter affecting Ra. Moreover, the result analysis shows that cutting speed of 240 m/min, feed rate of 0.12 mm/rev, and depth of cut of 0.4 mm) factor levels were the optimum cutting parameters for the output parameters (Fc and Ra). In turning experiments performed at optimum cutting parameters, the lowest Fc and Ra values were measured as 178N and 0.412 µm, respectively.
