Comparison of Hole Quality of Polyamide Materials Produced by Traditional and Additive Manufacturing

Abstract

Polyamide, commonly used in engineering plastics, has wear resistance and high strength. Hybrid manufacturing, using a combination of more than one production technique to benefit from the superiority of the manufacturing. In this study, polyamide, which is produced with casting and three-dimensional printer, has been drilled and reamed in numerical controlled machine. Thus, the effect of production technique, machining allowance and tool feed rate on hole surface and size quality was investigated. In general, the surface quality of the holes in the polyamide material produced by the two production techniques was directly affected by the machining allowance and the increased feed rate. In addition, the size of the holes created with the three-dimensional printer has reached the desired level after reaming process.

Geleneksel ve Eklemeli İmalat ile Üretilen Poliamid Malzemelerin Delik Kalitesinin Karşılaştırılması

Abstract

Yaygın olarak kullanılan mühendislik plastiklerinden polyamid, yüksek aşınma direnci ve yüksek mukavemete sahiptir. Hibrit imalat ise birden fazla üretim tekniğinin bir arada kullanılarak her bir üretim tekniğinin üstünlüklerinden faydalanmayı sağlar. Bu çalışmada, döküm ve üç boyutlu yazıcı ile üretilen polyamide malzemeye, nümerik kontrollü tezgahta delik delme ve raybalama işlemi yapılmıştır. Böylelikle, üretim tekniğinin, işleme payının ve takım ilerleme hızının delik yüzeyi ve boyut kalitesine etkisi incelenmiştir. Genel olarak her iki üretim tekniğiyle üretilen polyamid malzemedeki deliklerin yüzey kalitesi, işleme payından ve artan ilerleme hızından doğrudan etkilenmektedir. Ayrıca üç boyutlu yazıcı ile oluşturulan deliklerin boyut kalitesi raybalama işlemi sonrası istenilen seviyeye ulaşmıştır.
