Abstract (2. Language): 
Surface quality and dimensional precision significantly affect to strength and performance of working machine parts that are contacted one another. Additionally, cutting tool geometry and cutting parameters are the most important factor affecting to cutting force, surface roughness and productivity in machining. In this paper, optimization of cutting parameters and tool nose radius (variables) was performed for which Fc and Ra are occurred in machining of AISI 316L austenitic stainless steel. For this purpose, the machinability experiments were carried out using Taguchi’s L9 orthogonal array. An analysis of variance (ANOVA) was employed to determine the level of contribution and effects of variables on Fc and Ra values measured during the machining experiments. Optimal values of variables which were obtained using the S/N ratios were found at different levels for Fc and Ra. According to the ANOVA results, the most significant variable affecting to cutting force and surface roughness values was determined as feed rate.

Abstract (Original Language): 
Yüzey kalitesi ve ölçü tamlığı, temas halinde çalışan makine parçalarının dayanımını ve performansını önemli miktarda etkilemektedir. Bununla birlikte, talaşlı imalatta kullanılan kesici takım geometrisi ve kesme parametreleri; kesme kuvveti, yüzey pürüzlülüğü ve işleme verimliliğini etkileyen en önemli faktörlerdir. Bu çalışmada, AISI 316L östenitik paslanmaz çeliğinin işlenmesinde oluşan Fc ve Ra için kesici takım radyüsü ve kesme parametrelerinin (değişkenler) optimizasyonu yapılmıştır. Bu amaçla, Taguchi’nin L9 dikey dizini kullanılarak işlenebilirlik deneyleri gerçekleştirilmiştir. İşleme deneyleri sırasında ölçülen Fc ve Ra değerleri üzerinde değişkenlerin etkilerini ve önem seviyelerini belirlemek için varyans analizi (ANOVA) uygulanmıştır. S/N oranları kullanılarak tespit edilen değişkenlerin optimum değerleri, Fc ve Ra için farklı seviyelerde bulunmuştur. ANOVA sonuçlarına göre, kesme kuvveti ve yüzey pürüzlülüğünü etkileyen en önemli değişken ilerleme miktarı olarak belirlenmiştir.
