Daire Testere Makinesinde Bıçak Taşma Yüksekliği ve Diş Sayısına Bağlı Olarak Gürültü Emisyonunun Analizi

Öz

Daire testere makineleri ahşap işleme ve inşaat sektörlerinde yaygın olarak kullanılmasına rağmen, önemli bir gürültü kaynağıdır ve operatörler için işitme sağlığı riskleri oluşturur. Bu çalışma, masa testerelerinde gürültü emisyonunu etkileyen bıçak taşma yüksekliği ve diş sayısının etkilerini sistematik olarak araştırmayı amaçlamaktadır. Deneyler sırasında, yonga levha, MDF, çam ve kayın dahil olmak üzere çeşitli ahşap esaslı malzemeleri kesmek için dört farklı taşma yüksekliğine (5, 10, 15 ve 20 mm) ve üç farklı diş sayısına (28, 48 ve 60) sahip daire testere bıçakları kullanılmıştır. Gürültü seviyeleri, operatör maruziyetini simüle edecek şekilde konumlandırılmış bir ses seviyesi ölçer kullanılarak A ağırlıklı desibel (dBA) cinsinden ölçülmüştür. Toplanan veriler varyans analizi (ANOVA) ve Duncan'ın çoklu aralık testi kullanılarak istatistiksel olarak analiz edilmiştir. Sonuçlar, malzeme tipi, bıçak çıkıntı yüksekliği ve diş sayısının gürültü seviyeleri üzerinde istatistiksel olarak anlamlı etkileri olduğunu ortaya koymuştur (p ≤ 0,05). En düşük gürültü seviyeleri genellikle 5 mm bıçak çıkıntı yüksekliği ve 60 dişli bıçakla çam keserken elde edilmiştir.

Analysis of Noise Emission in Table Sawing in Relation to Blade Projection Height and Number of Teeth

Öz

Although table saws are widely used in the woodworking and construction industries, they are a significant source of noise pollution and pose hearing health risks for operators. This study aims to systematically investigate the effects of two primary factors influencing noise emission in table saws: blade projection height and number of teeth. During the experiments, 300 mm diameter circular saw blades with three different tooth counts (28, 48, and 60) were used at four different projection heights (5, 10, 15, and 20 mm) to cut various wood-based materials, including particleboard, medium-density fiberboard, pine, and beech. Noise levels were measured in decibels A-weighted (dBA) using a sound level meter positioned to simulate operator exposure. The collected data were statistically analyzed using analysis of variance (ANOVA) and Duncan’s multiple range test. The results revealed that material type, blade projection height, and number of teeth had statistically significant effects on noise levels (p ≤ 0.05). The lowest noise levels (averaging 79.61 dBA with the 60-tooth blade) were obtained when cutting pine with a 5 mm blade projection height. Conversely, the highest noise levels (averaging 84.87 dBA) were generated when cutting particleboard.
