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.

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.
