Ultrasonik ve Geleneksel Silindirik Tornalama İşlemlerinde Takım Tutucu Üzerindeki Yer Değiştirmenin Belirlenmesi

Bu çalışmada, ultrasonik ve geleneksel tornalama işlemlerinde takım tutucuda (kater) meydana gelen yer değiştirmeler deneysel olarak incelenmiştir. Deneysel çalışmada kesme hızı, ilerleme ve kesme derinliği gibi kesme parametreleri dikkate alınmıştır. Deneylerde AISI 310 paslanmaz çelik kullanılmıştır. Yer değiştirmeler torna tezgâhı tablası üzerine bağlanan KEYENCE lazer cihazı ile ölçülmüştür. Ultrasonik sistem ise üniversal bir torna tezgâhı üzerine bağlanmıştır. Ultrasonik sistemin çalışma frekansı 20 kHz ve genliği ise 15-20 µm civarındadır. Çalışma sonuçları göstermiştir ki, ultrasonik ile yapılan tornalama işlemindeki yer değiştirme değerleri geleneksel yönteme göre daha düşük elde edilmiştir. Ultrasonik ile yapılan tornalama işlemlerinde kater daha stabil bir davranış göstermiştir.

Determination of Displacements on Tool Holder in Ultrasonic and Conventional Cylindrical Turning Processes

In this study, displacements occurred on tool holder in ultrasonic and conventional turning processes have been determined as experimental. Cutting parameters such as depth of cut, feed rate and cutting speed has been considered in the experiments. AISI 310 stainless steel was used in the experiments. The displacements was measured by using KEYENCE laser apparatus attached on conventional turning machine. In addition, the ultrasonic system was attached on a conventional turning machine. Working frequency of the ultrasonic system is 20 kHz and also amplitude is almost 15-20 µm. The results shows that the displacement values occurred in ultrasonic turning process is very low in compared with conventional method. The tool holder is a more stable behavior in the turning processes by using ultrasonic.
