Abstract
Bu çalışmada, endüstriyel mutfak ürünlerinin plastik esaslı kompozit parçalarının montajında kullanılan, DIN 7981standartlarındaki sac vidası yerine plastik vidası kullanılmasının malzeme ömrü üzerine etkisinin araştırılması amaçlanmıştır.Bunun için, beyaz eşya sektöründe kullanılan plastik esaslı PC+ABS V0 hammaddeye sahip kompozit ürün numunelerialınmıştır. Bu numuneler ile gerçekleştirilecek deneyler için, iki farklı vida türü (plastik S1, saç P2), üç farklı sıkma torku(0,5, 0,7 ve 0,9 Nm) ve üç farklı vida çeşidi (V1:2,9x13 YSB,V2: 2,9x9,5 YSB, V3: 3,5x9,5 YSB) temin edilmiştir. Yapılançalışmada, farklı vida türü ile gerçekleştirilen deney sonuçları incelendiğinde, en iyi ömür sonucunu 0,5 sıkma torkunda V3kodlu plastik vida çeşidi, en kötü ömür sonucunu ise 0,7 ve 0,9 sıkma torkunda V1 kodlu saç vida çeşidinin verdiğibelirlenmiştir. Taguchi metodu ile gerçekleştirilen analiz sonrasında sinyal gürültü oranları incelendiğinde en ideal ömürdekullanılacak parametrenin vida türü için Seviye 2, sıkma torku için Seviye 1 ve vida çeşidi için Seviye 3 olarak belirlenmişt ir.Anova sonuçları incelendiğinde, vida ömründe en etkili parametrenin % 37,66 ile vida çeşidi, ikinci etkili parametrenin%28,11 ile vida türü ve en düşük etkinin ise %20,01 ile vida türü olarak oluştuğu tespit edilmiştir.
In this study, It is aimed to investigate the effect of plastic screw on material life instead of DIN 7981 standard sheet screw which is used in assembling plastic based composite parts of industrial kitchen products. For this purpose, samples of plasti c based PC + ABS V0 raw materials used in the white goods industry were taken. For experiments with these examples, two different types of screws (plastic S1, sheet P2), three different tightening torques (0.5, 0.7 and 0.9 Nm) and three different kinds of screws (V1:2.9x13 PH,V2: 2.9x9.5 PH, V3: 3.5x9.5 PH) are provided. In the study, when the results of the experiments performed with different types of screws were examined, it was determined that the best material life result was given by V3 coded plastic screw kind with 0,5 tightening torque and the worst material life result was given by V1 coded screw kind with 0,7 and 0,9 tightening torque. When the signal-to-noise ratios were analyzed with Taguchi method, the parameter to be used in the ideal material life was determined as Level 2 for screw type, Level 1 for tightening torque and Level 3 for screw kind. When Anova results were analyzed, it was found that the most effective parameter in screw life was screw kind with 37.66%, the second effective parameter was screw type with 28.11% and the lowest effect was screw type with 20.01%.
