Abstract

In this study, the cutting experiments of AISI 310 stainless sheet material on the laser bench were done and the effects of the processing parameters on the surface roughness and kerf width were investigated. Laser cutting experiments were carried out at two different gas pressures (0.8 bar and 1 bar), four different cutting speeds (20 mm.min-1, 24 mm.min-1, 28 mm.min-1 and 32 mm.min-1) and four different frequencies (3500 Hz, 4000 Hz, 4500 Hz and 5000 Hz). As a result of the experiments, the surface roughness and kerf width of the samples were measured. In addition, variance analysis were carried out to determine the effects of laser cutting parameters on surface roughness and kerf width. In laser cutting experiments, the optimum laser cutting parameter for the lowest (2.78 μm) surface roughness was 1 bar pressure, 5000 Hz frequency and 32 mm.min-1 cutting speed. For the lowest (0.79 mm) kerf width, the optimum laser cutting parameter was determined as 0.8 bar pressure, 3500 Hz frequency and 20 mm.min-1 cutting speed. In laser cutting experiments, it was observed that surface roughness values decreased with increasing cutting speed and frequency. While increasing the cutting speed caused the kerf width to decrease, the increase in the frequency value caused the kerf width to increase. As a result of variance analysis, it was determined that the most effective parameter cutting speed on surface roughness with 38.67% and kerf width with 49.50%.

AISI 310 Kalite Östenitik Paslanmaz Sac Malzemenin Lazerle Kesilmesinde Kesme Parametrelerinin Kesim Kalitesine Etkisinin İncelenmesi

Abstract

Yapılan çalışmada, AISI 310 paslanmaz sac malzemesinin lazer tezgâhında kesilmesiyle kesme parametrelerinin yüzey pürüzlülüğü ve kerf genişliğine etkileri araştırılmıştır. Lazer kesme deneyleri iki farklı gaz basıncı (0.8 bar ve 1 bar), dört farklı kesme hızı (20 mm.dak-1, 24 mm.dak-1, 28 mm.dak-1ve 32 mm.dak-1) ve dört farklı frekansta (3500 Hz, 4000 Hz, 4500 Hz ve 5000 Hz) yapılmıştır. Deneyler sonucunda numunelerin yüzey pürüzlülüğü ve kerf genişliği ölçülmüştür. Ayrıca lazer kesme parametrelerinin yüzey pürüzlülüğü ve kerf genişliği üzerine etkilerini belirlemek amacıyla varyans analizleri yapılmıştır. Lazer kesme deneylerinde en düşük (2.78 μm) yüzey pürüzlülüğü için optimum lazer kesme parametresi olarak 1 bar basınç, 5000 Hz frekans ve 32 mm.dak-1 kesme hızı olmuştur. En düşük (0.79 mm) kerf genişliği için optimum lazer kesme parametresi 0.8 bar basınç, 3500 Hz frekans ve 20 mm.dak-1 kesme hızı olarak tespit edilmiştir. Lazer kesme deneylerinde kesme hızının ve frekansın artması ile yüzey pürüzlülük değerlerinin azaldığı görülmüştür. Kesme hızının artırılması kerf genişliğinin azalmasına neden olurken, frekans değerinin artması kerf genişliğinin artmasına neden olmuştur. Varyans analizlerinin sonucunda da % 38.67 ile yüzey pürüzlülüğü ve % 49.50 ile kerf genişliği üzerine en etkin parametre kesme hızının olduğu tespit edilmiştir.
