Abstract:

 In this study, it was aimed to investigate the effect of feed 0.1-0.15-0.2 mmrev and printing temperature 190-210-230C on the formation of burrs and circularity in the drilling of samples produced using polylactic acid PLA material with the fused deposition modelling FDM technique, which is an additive manufacturing AM method. In the results obtained, it was observed that the burr height increased with the increase of the feed in the drilling of the samples, and the burr height decreased with the increase of the printing temperature. The maximum burr height at the hole entrance was 0.32 mm 0.2 mmrev, 190C, while the maximum burr height at the hole exit was 0.37 mm 0.2 mmrev, 190C. The maximum circularity deviation at the hole entrance was 0.15 mm 0.2 mmrev, 230C and the maximum circularity deviation at the hole exit was 0.1 mm 0.2 mmrev, 190C. In addition, prediction modelling for burr height and deviation from circularity was performed with an average success rate of R2 94.

 Bu çalışmada, eklemeli imalat EK yöntemlerinden biri olan eritilmiş biriktirme modelleme FDM tekniği ile polilaktik asit PLA malzeme kullanılarak üretilen numunelerin delinmesinde, besleme ve baskı sıcaklığının çapak oluşumuna etkisinin incelenmesi amaçlanmıştır. Bu kapsamda üç farklı baskı sıcaklığında 190-210-230 C delme işlemine tabi tutulacak numuneler üretilmiştir. Delme işlemi 1500 devdak. mil ve üç farklı besleme 0,1-0,15-0,2 mmdevir ayarında gerçekleştirilmiştir. Elde edilen sonuçlarda, numunelerin delinmesinde beslemenin artmasıyla çapak yüksekliğinin arttığı, baskı sıcaklığının artmasıyla çapak yüksekliğinin azaldığı görülmüştür. Ayrıca, çapak yüksekliği ve dairesellikten sapma için makine öğrenmesi yöntemi ile tahmin modellemesi yapılmıştır. Ortalama 94lük bir başarı oranı ile baskı sıcaklığının ve beslemenin delik delme işleminde çapak yüksekliği ve dairesellikten sapmaya etkisi tahmin edilmiştir.
