Yumuşak çelikte malzeme kaldırma süreçlerinin analizi: iş mili hızı, ilerleme hızı ve kesme derinliğinin işleme performansı üzerindeki etkisi

Öz

Bu çalışma, yumuşak çelik işleme sırasında iş mili hızı, ilerleme hızı ve talaş derinliğinin işleme performansı üzerindeki etkilerini incelemektedir. Deneyler, 105-225 rpm aralığında iş mili hızı, 0.10-0.34 mm/dev ilerleme hızı ve 1.0-3.4 mm talaş derinliği değerleriyle gerçekleştirilmiştir. Sonuçlar, bu parametrelerin artırılmasının malzeme kaldırma oranını (MRR) iyileştirdiğini göstermiştir; en yüksek MRR değeri 261.30 mm³/dak olarak kaydedilmiştir. Ancak, takım aşınma oranı da orantılı olarak artmış ve maksimum 7.65 mm³/dak değerine ulaşarak, yüksek verimlilik ile takım ömrü arasında bir denge olduğunu ortaya koymuştur. İşleme süresi ise artan iş mili hızıyla azalmış ve en kısa süre 1.35 dakika olarak ölçülmüştür. Eşleştirilmiş örneklem t-testi ve korelasyon katsayıları kullanılarak yapılan istatistiksel analizler, iş mili hızı ile MRR arasında güçlü pozitif (r=0.973), iş mili hızı ile takım aşınma oranı arasında güçlü pozitif (r=0.994) ve iş mili hızı ile işleme süresi arasında güçlü negatif (r=-0.935) korelasyonlar ortaya koymuştur. Bu bulgular, üretkenlik, takım aşınması ve verimlilik arasında denge sağlamak için kesme parametrelerinin optimize edilmesinin önemini vurgulamaktadır. Çalışma, endüstriyel yumuşak çelik işleme uygulamaları için değerli bilgiler sunmakta ve benzer koşullarda gelişmiş soğutma yöntemleri ile takım malzemelerinin etkisinin araştırılmasını önermektedir. Bu sonuçlar, hassas üretim süreçlerinin ve kaynak optimizasyonunun geliştirilmesine katkı sağlar.

Influence of spindle speed, feed rate, and depth of cut on machining performance: an analysis of material removal processes in mild steel

Abstract

This study examines the effects of spindle speed, feed rate, and depth of cut on machining performance during mild steel machining. Experiments were conducted with spindle speeds ranging from 105-225 rpm, feed rates of 0.10-0.34 mm/rev, and depths of cut between 1.0-3.4 mm. Results showed that increasing these parameters improved the material removal rate (MRR), with the highest MRR reaching 261.30 mm³/min. However, tool wear rate also rose proportionally, peaking at 7.65 mm³/min, highlighting a trade-off between productivity and tool durability. Machining time decreased with higher spindle speeds, with the shortest time recorded at 1.35 minutes. Statistical analysis using paired sample t-tests and correlation coefficients revealed strong positive correlations between spindle speed and MRR (r=0.973), spindle speed and tool wear rate (r=0.994), and a strong negative correlation between spindle speed and machining time (r=-0.935). These findings highlight the importance of optimizing cutting parameters to balance productivity, tool wear, and efficiency. The study provides practical insights for industrial machining of mild steel and recommends future exploration into advanced cooling methods and tool materials to enhance machining performance under similar conditions, contributing to improved precision and resource efficiency.
