AISI 4140 steel is in the class of medium carbon low-alloy steels and widely used industry due to its high hardenability being a relatively economical steel. also among that can be nitrided. With nitriding process, thanks hard nitride layer obtained on surface, not only wear-resistant surface provided, but an increase fatigue strength. In this study, microstructural properties steel, which has ...

Abstract One of the essential requirements for intelligent manufacturing is low cost and reliable predictions tool life during machining. It crucial to monitor condition cutting achieve cost-effective high-quality Tool conditioning monitoring (TCM) determining remaining useful assure uninterrupted machining manufacturing. The same can be done by direct indirect wear measurement prediction techn...

Bu çalışmada, AISI 4140 çeliğinin tornalanması işleminde kesme hızı, ilerleme oranı ve MQL debisinin esas kuvvetleri (Fc) ortalama yüzey pürüzlülüğüne (Ra) etkisi hem deneysel de istatiksel olarak incelenmiştir. doğrultuda deney sonuçlarının değerlendirilmesinde sinyal/gürültü (S/N) oranları yapay sinir ağları (YSA) kullanılmıştır. İşleme deneylerinde, parametreleri üç farklı hızı (75, 100, 125...

In the manufacturing field, a growing interest is being held to environment, sustainability and more precisely saving energy time. Combining thermomechanical with pure mechanical processes an eco-friendly profitable technique. this paper, it proposed combine grinding ball-burnishing processes. Further from reducing time, cost of operations, original combination imagined take benefit history occ...
