Özet:

 Aim of this study examines the impact of processing parameters and lattice structures on delamination during the drilling of cylinder PLA Polylactic acid parts. The parts were designed with four different lattice structures gyroid, I-WP, nevoius, and diamond and produced using a 3D printer. A 5 mm HSS drill was used to drill from the center point. After drilling, images of the entrance and exit holes were captured using a digital microscope. The delamination, burr, and circularity around the hole were analyzed. The results showed that the Gyroid and I-WP lattice structures had the lowest delamination at the entrance and exit holes. No burr was observed at the entrance of the specimens. The Nevoius lattice structure exhibited the lowest burr value at the hole exit and entrance, as well as the lowest exit circularity deviation. Among the samples, the highest delamination was observed at the hole entrance in I-WP 0.5601, while the lowest delamination was observed in Gyroid 0.5423. At the hole exit, the highest delamination was observed in Gyroid 0.6229, and the lowest delamination was observed in I-WP 0.5426.

 Bu çalışmanın amacı, kafes yapıların delinmesinde işleme parametrelerinin ve farklı kafes yapılarının delaminasyon üzerindeki etkilerinin araştırılmasıdır. Bu kapsamda dört farklı gyroid, I-WP, nevoius ve elmas kafes yapısında tasarlanan silindir PLA Polilaktik asit parçalar 3D yazıcıda üretilmiş ve 5 mm HSS matkap ile merkez noktadan delinmiştir. Delme işleminden sonra dijital mikroskop ile giriş ve çıkış delik görüntüleri alınmış ve delik çevresinde delaminasyon, çapak ve dairesellik analizleri yapılmıştır. Elde edilen sonuçlara göre deliğin girişinde en düşük delaminasyon Gyroid ve çıkışında I-WP kafes yapısında ölçülmüştür. Numunelerin delik girişinde çapak oluşmamıştır. Delik çıkışında çapak, giriş ve çıkış dairesellik sapması açısından en düşük değere sahip numunenin Nevoius kafes yapısı olduğu görülmektedir. Delik girişinde en yüksek delaminasyon I-WPde 0.5601, en düşük delaminasyon ise Gyroidde 0.5423 gözlemlenmiştir. Delik çıkışında en yüksek delaminasyon Gyroid 0.6229 numunesinde, en düşük delaminasyon ise I-WP 0.5426 numunesinde gözlemlenmiştir.
