Abstract

In this study, studies on unstable temperature distribution, one of the biggest problems of joint manufacturing, have been evaluated. Heterogeneous temperature distributions, residual stresses and dimensional changes were investigated, which are the most important factors in manufacturing faults. The problems that arise during manufacturing in different types of metal materials have been evaluated in terms of direct metal laser sintering (DMLS) and manufacturing method. The faulty effect of manufacturing parameters has been investigated. Different approaches on pre-manufacturing temperature and error estimation were also discussed with finite element analysis. As a result, what needs to be done to rectify the mistakes is revealed in the light of the available information.

Özet

Bu Çalışma, eklemeli imalatın en önemli problemlerinden bir tanesi olan dengesiz sıcaklık dağılımı üzerine yapılan çalışmaların araştırılmasını konu almaktadır. İmalat esnasında meydana gelen hatalara etki eden önemli parametrelerden olan heterojen sıcaklık dağılımı, kalıntı gerilemeler ve boyutsal değişimler araştırılmıştır. Farklı tip metal malzemelerin doğrudan metal lazer sinterleme (DMLS) yöntemi ile imalatı esnasında parça üzerinde meydana gelen sorunlar incelenmiştir. İmalat parametrelerinin meydana gelen hatalara olan etkisi incelenmiştir. Sonlu elemanlar analizleri ile imalat öncesi sıcaklık ve hata tahmini konusunda gerçekleştirilmiş farklı yaklaşımlar da ele alınmıştır. Sonuç olarak hataların giderilmesi konusunda yapılması gerekenler, mevcut bilgiler ışığında ortaya konulmuştur.
