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...

AISI 4140 steel is still one of the most distinguished steels employed in tribological applications because its low cost, great mechanical properties, and appropriate wear resistance. In this contribution, performance annealed against engineering ceramic was analyzed to promote parameters for application steel, especially systems that are subjected contact pressures between 490–1240 MPa. Dry lu...
