AISI 316L Alaşımın Tel Erozyon Yöntemi ile İşlenmesinde Kesme Parametrelerinin Yüzey Kalitesine Etkisi

Öz

Endüstride kullanımı oldukça yaygınlaşan tel erozyonla işleme teknolojisi, özellikle geleneksel imalat yöntemleri ile üretilmesi zor parçaların imalatı ve düşük enerji tüketimi bakımından imalat sektöründe önemli bir yere sahiptir. Bu çalışmada, AISI 316L östenitik paslanmaz çelik alaşımın tel erozyon yöntemi ile işlenmesi sırasında farklı kesme parametrelerinin yüzey kalitesi üzerinde oluşturduğu etkilere odaklanılmıştır. Bununla birlikte üretim süresini uzatmadan yüzey kalitesinin arttırılması amaçlanmıştır. Bu kapsamda, farklı kesme parametreleri ile tam faktöriyel tasarımda deneysel çalışmalar yapılmış, devamında varyans ve regresyon analizleri ile kesme parametrelerinin yüzey kalitesi üzerindeki davranışları araştırılmıştır. Sonuç olarak, ilerleme hızı ve bombardıman süresinin artması ve bekleme süresinin azalması ile yüzey pürüzlülük değerlerinde artış eğilimi görülmüştür. En düşük yüzey pürüzlülük değeri, 2 mm/dak ilerleme hızı, 16 µs bombardıman süresi ve 480 µs bekleme süresi parametrelerinde elde edilmiştir. İstatistiksel veri analizleri sonucunda, yüzey kalitesi açısından en etkin kesme parametresinin %83,96 oranla bombardıman süresi olduğu tespit edilmiştir.

The Impact of the Cutting Parameters on the Surface Quality of AISI 316L with WEDM

Abstract

Wire electrical discharge machining (WEDM) which is widely used in the industry has an important place in the manufacturing process. WEDM is a preferred manufacturing method, especially in terms of the production of parts that are difficult to produce with traditional manufacturing methods and low energy consumption. This focused on the effects of different cutting parameters on the surface quality of AISI 316L austenitic stainless steel alloy during wire erosion processing. In addition, it is aimed to increase the surface quality without extending the production period. In this context, experimental studies were carried out in full factorial design with different cutting parameters, and then the behavior of the cutting parameters on the surface quality was investigated with variance and regression analyses. As a result, an increasing trend was observed in the surface roughness values with the increase in the feed rate and pulse on time and the decrease in the pulse off time. The lowest surface roughness value was obtained at 2 mm/min feed rate, 16 µs pulse on time, and 480 µs pulse off time parameters. As a result of statistical data analysis, it was determined that the most effective cutting parameter in terms of surface quality was the pulse time with a rate of 83.96%.
