Abstract

In this study, the variation of surface roughness of parts with varying machining parameters is investigated experimentally in Computer Numeric Control (CNC) machine tools. The experiments are conducted using Cincinnati Avenger 200 MT and Topper TNL 100 CNC lathes, Cincinnati Lancer 1500 CNC vertical milling machine and Defum DBN 100N CNC horizontal milling machine. The specimens used in the experiments are selected from the daily production schedule of the factory. In the experiments, machining parameters, namely cutting tool feedrate, spindle speed, table feed and depth of cut, are changed and the variation of the average surface roughness is observed. It is found that the surface roughnessdecreases with increasing spindle speed in CNC turning machines and .vertical, horizontal-milling machines and it increases with increasing feed rate of the cutting tool/worktable.

Özet

Bu çalışmada, bilgisayar sayısal denetimli (BSD) tezgahlarda değişik işleme koşulları ile işlenmiş parçaların yüzey pürüzlülüğünün gösterdiği değişim deneysel olarak incelenmiştir. Deneyler, Cincinnati Avenger 200 MT ve Topper TNL 100 BSD torna, Cincinnati Lancer 1500 BSD dik işleme merkezi ve Defum DBN 100N BSD borverg tezgahlarında gerçekleştirilmiştir. Deney numuneleri olarak, fabrikanın olağan üretim planında yer alan partilerden seçilen parçalar kullanılmıştır. Deneylerde, takım ilerleme hızı, iş parçası/takım dönme hızı, tabla ilerlemesi ve paso derinliği gibi işleme parametreleri değiştirilmiş ve ortalama yüzey pürüzlülüğünün gösterdiği değişim incelenmiştir. Fener mili/iş mili dönme hızı arttırıldığında yüzey pürüzlülüğünün iyileştiği, takım ilerlemesi/tabla ilerlemesi arttırıldığında yüzey pürüzlülüğünün kötüleştiği görülmüştür.
